A Small Computer With a Surprisingly Big Ambition
There is something deeply satisfying about building a computer that does not look like a conventional computer at all. Instead of another thin laptop or tablet, Raspberry Pi’s latest DIY project turns a rugged waterproof briefcase into a portable workstation, combining a Raspberry Pi 5, display, keyboard, storage, and power system into one compact enclosure.
The project, highlighted by Raspberry Pi and reported by TechRadar, is a modern example of the cyberdeck concept: a custom-built computer designed around a specific purpose rather than mass-market aesthetics.
And perhaps the most impressive part is the price.
The complete build can reportedly be assembled for roughly $250.09, depending on component prices and what materials you already have available. That puts the project within reach of hobbyists who want something more interesting than simply assembling another desktop PC.
What Exactly Is a Cyberdeck?
A Computer Designed Around the User
The term cyberdeck does not describe one particular computer model. Instead, it refers to a custom computing device built around a particular need, environment, or creative vision.
Cyberdecks can take almost any form. Makers have built them inside briefcases, wooden boxes, old laptops, handheld enclosures, metal cases, retro computer shells, and even objects that look like science-fiction props.
The philosophy is simple: instead of asking what a computer manufacturer wants you to use, you decide what your computer should be.
Why the Briefcase Matters
The Case Becomes Part of the Computer
Maker Brian Corteil, who created the Raspberry Pi guide, puts considerable emphasis on the enclosure itself.
The rugged briefcase is not simply a container for the electronics. It effectively becomes the foundation of the entire cyberdeck.
A waterproof, hard-shell case provides physical protection while also creating a practical structure for mounting the electronics, screen, battery or power components, keyboard, and accessories.
That changes the project from a Raspberry Pi sitting inside a box into something that feels like a purpose-built field computer.
Raspberry Pi 5 Provides the Computing Power
Small Hardware With Serious Potential
At the heart of the cyberdeck is the Raspberry Pi 5, which provides considerably more performance than earlier generations of Raspberry Pi boards.
The Pi 5 is powerful enough for everyday Linux applications, programming, networking tools, lightweight development environments, media playback, electronics projects, and a wide range of command-line utilities.
For a cyberdeck, that makes it particularly attractive.
You do not need a huge desktop tower when the objective is portability. You need a computer that can perform useful tasks while consuming relatively little space and power.
The Keyboard Makes It Feel Like a Real Computer
Bluetooth Keeps the Design Flexible
The project uses a Bluetooth keyboard rather than relying on a permanently attached traditional laptop keyboard.
That approach provides more flexibility when arranging components inside the case.
It also allows the keyboard to be moved or replaced without completely redesigning the enclosure.
For people building their own cyberdeck, this is an important lesson: modular components can make future upgrades dramatically easier.
The Display Completes the System
A Computer Needs Somewhere to Show Its Work
A Raspberry Pi board alone is not particularly useful as a portable workstation.
The cyberdeck therefore incorporates a display into the case, giving the user a complete computing environment without requiring an external monitor.
This is one of the defining differences between a simple Raspberry Pi project and a genuine portable computer.
The screen, keyboard, storage, power system, and computer all become part of one integrated machine.
Built-In Power Makes It More Interesting
Freedom From the Wall Socket
One of the most compelling aspects of the build is its integrated power system.
Instead of requiring the cyberdeck to remain connected to a conventional outlet, the system is designed to operate as a portable machine.
That opens the door to a completely different set of applications.
A portable Raspberry Pi can be used for field experiments, programming, network diagnostics, electronics work, educational projects, remote monitoring, documentation, and countless other tasks.
It does not have to replace a conventional laptop.
Its advantage is that it can be designed for situations where a conventional laptop may not be ideal.
The $250 Price Makes the Project Surprisingly Accessible
Affordable, But Not Free
According to the original article, adding up the recommended components produces a total of approximately $250.09, or around £184 / AU$348 based on the figures provided in the source.
That is an attractive price for a complete custom computer.
However, the $250 figure should be viewed as a project estimate rather than a guaranteed final price.
Component prices change, shipping costs vary, and some builders may already have useful parts sitting around.
The total can also rise if you decide to use a higher-quality screen, larger battery, premium storage, custom machining, or more sophisticated cooling.
The Hidden Cost Is Your Time
DIY Projects Have More Than One Price
The most important thing to understand about a cyberdeck is that the bill of materials is only part of the investment.
You also need time.
Mounting components inside a rugged case requires planning. The internal supports may need to be 3D-printed, laser-cut, or fabricated manually.
Then comes wiring.
Then power management.
Then cooling.
Then software configuration.
Then testing.
A $250 cyberdeck can easily become a much more expensive project if you repeatedly redesign parts of it.
But that is also the appeal.
The process itself is part of the experience.
3D Printing Opens the Door to Custom Designs
The Case Does Not Have to Stay Stock
The requirement for internal supports means makers can customize the machine extensively.
A 3D printer can be used to create brackets for the display, mounting plates for electronics, cable guides, keyboard supports, battery holders, and other structural components.
That turns the project into more than computer assembly.
It becomes a combination of computing, electronics, mechanical design, fabrication, and software engineering.
Why Raspberry Pi Is Perfect for Cyberdecks
Linux Makes the Hardware Flexible
The Raspberry Pi ecosystem has always benefited from the flexibility of Linux.
Instead of being locked into one operating environment, users can install software packages, configure services, write scripts, connect sensors, experiment with networks, and customize virtually every part of the system.
That matters enormously for cyberdecks.
The hardware becomes a blank canvas.
A Portable Linux Workstation
More Than a Raspberry Pi Toy
It would be easy to dismiss a project like this as a novelty.
That would be a mistake.
A Raspberry Pi 5 inside a rugged enclosure can function as a legitimate lightweight Linux workstation.
It can run terminals, editors, programming environments, local documentation, networking utilities, web applications, automation scripts, and various development tools.
For some users, that is all the computer they need.
The Cyberdeck Philosophy Is Bigger Than Raspberry Pi
Build What Commercial Computers Cannot Offer
The real story here is not simply that Raspberry Pi has published instructions for a $250 computer.
It is that cyberdecks challenge the conventional idea of what a computer should look like.
Commercial manufacturers optimize devices for the largest possible audience.
Cyberdeck builders optimize devices for themselves.
That distinction is powerful.
From Briefcases to Science-Fiction Machines
Makers Have Already Taken the Concept Much Further
The Raspberry Pi project is only one point on a much larger spectrum.
Cyberdeck communities have produced tiny portable systems, clamshell designs, multi-screen machines, handheld computers, retro-inspired terminals, and elaborate creations that appear to have been pulled directly from a science-fiction movie.
Some designs are practical.
Others are deliberately excessive.
Both approaches are valid.
The whole point is experimentation.
The Official Raspberry Pi Magazine Connection
A Larger Cyberdeck Movement
The project was also featured in Raspberry Pi Official Magazine issue 168, which focused specifically on cyberdecks.
That is significant because it demonstrates that the concept has moved beyond isolated hobbyist experiments.
There is now an established maker culture surrounding custom portable computing.
For anyone who becomes fascinated with this project, the briefcase computer can be treated as a starting point rather than a final destination.
Building the Cyberdeck Step by Step
Step 1: Choose the Enclosure
The case determines almost everything else.
Measure the available internal dimensions before purchasing the remaining hardware.
The display, keyboard, Raspberry Pi, battery, storage, cables, and mounting hardware all need to fit without creating dangerous pressure points.
Step 2: Plan the Internal Layout
Do not immediately start drilling or cutting.
Create a physical or digital layout first.
Think about where each component will go and how cables will travel between them.
A good cyberdeck should not only work. It should also be serviceable.
Step 3: Mount the Raspberry Pi
The Raspberry Pi 5 should be mounted securely while leaving enough room for cooling and access to its ports.
Avoid placing it directly against surfaces that could interfere with airflow.
Step 4: Install the Display
The screen should be positioned so that it can be viewed comfortably when the case is open.
The mounting system should also protect the display when the cyberdeck is closed.
Step 5: Add the Keyboard
The Bluetooth keyboard keeps the system relatively simple.
Depending on the design, the keyboard can be stored inside the case or positioned in a way that allows the entire cyberdeck to function like a portable workstation.
Step 6: Add Storage
A reliable storage solution is essential.
The operating system, applications, documents, scripts, and other files all need somewhere to live.
For a portable system, reliability is more important than chasing maximum theoretical storage performance.
Step 7: Build the Power System
The power system deserves special attention.
A portable computer is only as useful as its battery life and power reliability.
The system should be designed so that power delivery remains stable under load.
Step 8: Test Before Closing the Case
This is one of the most important steps.
Test every component before permanently installing it.
Confirm the display works.
Confirm the keyboard works.
Confirm storage works.
Confirm the Raspberry Pi boots correctly.
Confirm the power system behaves properly.
Finding a problem before everything is mounted can save hours of frustrating disassembly.
Deep Analysis: Turning a Raspberry Pi Into a Real Field Computer
Linux Gives You the Command Line
Once the hardware is working, the cyberdeck becomes much more interesting through software.
A Raspberry Pi running Linux can be transformed into a highly customized field workstation.
For example, you can inspect the system with:
uname -a
Checking Hardware Resources
You can examine CPU and memory information with:
lscpu free -h
These commands help determine how much processing power and RAM are available for your applications.
Monitoring Storage
Storage usage can be checked with:
df -h
For a portable computer, monitoring storage is particularly useful because large log files, captured data, downloaded packages, or media can eventually consume available space.
Checking Network Interfaces
A cyberdeck can also become a useful networking workstation.
Use:
ip addr
This shows the available network interfaces and their assigned addresses.
Testing Connectivity
Basic connectivity can be tested with:
ping -c 4 1.1.1.1
This is useful when troubleshooting whether a network connection is functioning.
Inspecting Running Processes
You can see active processes with:
ps aux
For a more interactive view:
top
These tools are useful when determining why a portable system is consuming CPU or memory.
Checking USB Hardware
When connecting external peripherals, you can inspect USB devices with:
lsusb
This becomes especially valuable on a cyberdeck because USB devices may include storage, networking adapters, serial interfaces, microcontrollers, and other hardware.
Checking Temperature
The Raspberry Pi 5 can generate meaningful heat under sustained workloads.
A simple temperature check can be performed with:
vcgencmd measure_temp
Keeping an eye on temperature is important when the computer is enclosed inside a rugged case.
Updating the System
A basic Debian-based Raspberry Pi installation can be updated with:
sudo apt update sudo apt full-upgrade
Keeping the operating system patched is particularly important if the cyberdeck will connect to public networks.
Installing Useful Development Tools
A portable development machine can be equipped with common tools such as:
sudo apt install git curl wget vim
This gives the system a basic toolkit for software development and command-line work.
Building a Portable Programming Station
With Git and a code editor installed, the cyberdeck can become a surprisingly capable development environment.
A maker could write Python applications, control electronics, interact with sensors, maintain scripts, or build small web applications directly from the case.
Network Administration Potential
The hardware can also be configured for legitimate network administration and diagnostic work.
Tools such as SSH clients, network monitoring utilities, DNS tools, and packet-analysis software can turn the cyberdeck into a portable troubleshooting station.
The key word is authorized.
A portable computer should be used to diagnose networks and systems you own or have explicit permission to test.
What Undercode Say:
The $250 Number Is Not the Most Important Part
The headline price is attractive, but the deeper story is the freedom this project provides.
Raspberry Pi Has Become a Maker Platform
Raspberry Pi is no longer simply a tiny educational computer.
It has evolved into a foundation for serious experimentation.
Cyberdecks Encourage Ownership
A commercial laptop gives you a finished product.
A cyberdeck gives you control over the product.
The Enclosure Changes the Experience
Putting the electronics inside a rugged case immediately changes how the computer feels.
It becomes equipment rather than another consumer gadget.
Portability Becomes a Design Goal
Traditional computers are designed to be portable within certain limits.
A cyberdeck is designed around portability from the beginning.
Ruggedness Has Real Value
A hard waterproof enclosure can protect expensive electronics from environmental conditions that ordinary laptops are not designed to tolerate.
Customization Is the Biggest Advantage
Users can choose their display, storage, keyboard, battery, networking hardware, cooling system, and software environment.
The Raspberry Pi 5 Is Powerful Enough
The Pi 5 offers enough performance for a surprisingly broad range of lightweight computing tasks.
Linux Makes the Difference
The operating system gives users access to a huge ecosystem of tools and customization options.
This Is Not Designed to Beat a MacBook
That is not the objective.
The cyberdeck exists because a MacBook cannot provide the same level of physical customization.
DIY Computing Is Having a Moment
As increasingly closed consumer devices dominate the market, projects like this remind people that computers can still be understandable and modifiable machines.
The Hardware Is Only Half the Project
The real creativity happens when the hardware and software are designed together.
The Case Creates Constraints
Those constraints are actually useful.
Limited space forces the builder to think carefully.
Every Cable Matters
Good cable management can be the difference between a professional-looking build and a frustrating mess.
Cooling Deserves Attention
The Pi
Battery Design Matters Too
Portable computing requires careful thinking about capacity, voltage, charging, and safe power delivery.
Field Computing Could Be a Major Use Case
A rugged Raspberry Pi workstation could be useful for technicians, engineers, educators, researchers, and makers.
Education Is Another Natural Application
Students can learn Linux, electronics, programming, networking, and mechanical design through one project.
Cyberdecks Encourage Experimentation
The project does not tell you what the final computer must become.
It gives you a starting point.
A $250 Build Can Become a Learning Platform
The hardware cost is relatively modest compared with the number of skills that can be developed through the project.
The Project Can Grow Over Time
You can start with the basic configuration and add sensors, storage, networking hardware, or other peripherals later.
Repairability Is Valuable
A custom computer can often be opened and repaired rather than discarded.
Commercial Devices Rarely Offer This Freedom
Modern laptops increasingly prioritize thinness and integration.
That makes them convenient, but often harder to modify.
Cyberdecks Go in the Opposite Direction
Instead of hiding the technology, they celebrate it.
The Visual Style Is Part of the Appeal
Cyberdecks often look unusual because they are not constrained by mainstream product design.
Science Fiction Influences the Culture
The name and aesthetic clearly connect with decades of fictional portable computing concepts.
But the Technology Is Real
Unlike fictional cyberpunk machines, this project can actually be built on a workbench.
The Community Matters
Once a maker starts experimenting, other
One Design Can Lead to Another
A briefcase build today could inspire a handheld device tomorrow.
The $250 Figure Is Only a Baseline
Better screens, larger batteries, custom fabrication, and additional electronics can increase the final cost.
Existing Parts Can Reduce the Price
Builders who already own a keyboard, storage drive, display, or 3D printer may spend considerably less.
The Real Investment Is Creativity
The most valuable component is not the Raspberry Pi.
It is the person building around it.
This Is What Makes the Project Exciting
It takes inexpensive computing hardware and turns it into something personal.
The Future Could Be More Modular
As makers continue experimenting, cyberdecks may become increasingly modular and easier to upgrade.
Raspberry Pi Fits That Future
The
The Cyberdeck Is More Than a Gadget
It represents a different philosophy of computing.
Build Instead of Buy
That may ultimately be the most important message behind the project.
✅ Raspberry Pi 5 Is the Core Platform
The article correctly identifies the Raspberry Pi 5 as the central computing component of the featured cyberdeck. The board is well suited to portable Linux projects because of its performance, connectivity, and compact size.
✅ The Build Uses a Rugged Briefcase-Style Enclosure
The project is based around a hard protective case, which is central to its cyberdeck design. The enclosure provides portability while protecting the electronics.
✅ The Reported Cost Is Around $250
The original article calculates the suggested component list at approximately $250.09. Actual costs can vary depending on retailer pricing, shipping, availability, and optional upgrades.
❌ $250 Does Not Mean Every Cyberdeck Costs $250
The figure should not be interpreted as a universal cyberdeck price. Different displays, batteries, storage devices, fabrication requirements, and accessories can substantially change the final cost.
✅ Custom Fabrication Is Part of the Build
The project requires internal supports and mounting components that may need to be 3D-printed, laser-cut, or otherwise fabricated. That means the project involves considerably more than simply buying a Raspberry Pi.
Prediction
(+1) Cyberdecks Will Become More Popular Among Makers
As compact computers become more powerful, the number of people experimenting with custom portable workstations is likely to grow.
(+1) Raspberry Pi Will Remain a Strong Platform for DIY Computing
Its combination of Linux support, community resources, accessories, and compact hardware makes Raspberry Pi particularly attractive for experimental computer designs.

(-1) Component Costs Could Push Some Builds Above $250
Hardware prices are not fixed, and premium displays, batteries, storage, cooling, and custom fabrication can quickly increase the final bill.
(+1) The Biggest Value Will Remain the Learning Experience
Even if the final computer is eventually replaced by a conventional laptop, the skills gained from designing, wiring, programming, troubleshooting, and modifying the cyberdeck can last much longer than the hardware itself.
The Bigger Lesson Behind Raspberry Pi’s Cyberdeck
A Computer Does Not Have to Look Like a Laptop
The most exciting thing about this project is not the waterproof case or even the $250 price tag.
It is the reminder that computing can still be personal.
A Raspberry Pi 5, a screen, a keyboard, storage, power system, and a rugged enclosure are enough to create something that feels completely different from the computers filling electronics stores today.
The Future of DIY Computing Is Personal
The commercial technology industry is moving toward thinner devices, sealed hardware, integrated components, and increasingly sophisticated software ecosystems.
Cyberdecks move in the opposite direction.
They expose the hardware.
They encourage modification.
They invite experimentation.
And they let the builder decide what the computer should become.
A $250 Cyberdeck Is Only the Beginning
The real achievement is not building the exact machine shown in the Raspberry Pi guide.
It is taking the concept and making it your own.
Add another display.
Change the keyboard.
Increase the storage.
Build a better battery system.
Add sensors.
Connect external electronics.
Create a custom interface.
Turn it into a programming workstation.
Turn it into a field research computer.
Or simply build something that looks like it escaped from a futuristic movie.
That is the beauty of the cyberdeck philosophy: there is no single correct version.
And with the Raspberry Pi 5 at its center, a rugged case around it, and roughly $250 worth of hardware to get started, this particular project makes a compelling argument that the most interesting computer in your future might be the one you build yourself.
