Which Raspberry Pi Models Work Best as a PC?

While it’s entirely possible to use the Raspberry Pi as a cheap, entry-level desktop PC, it’s important to remember that the Raspberry Pi was not designed for that purpose – it wasn’t built to replace the traditional computer.

Therefore, if you want to use a Raspberry Pi as a PC alternative, you need a Raspberry Pi model that fits that purpose.

Many Raspberry Pi models available today come with different features and resources. Let’s get a good understanding of some of the models that would give the best performance when used as a PC:

• Raspberry Pi 5: This is the latest release of the Raspberry Pi models – released on November 2023. It boasts significant upgrades from its predecessor, the Raspberry Pi 4, especially in CPU and GPU. So far, it is the best model to use as a PC.

Setting Up Your Raspberry Pi

I assume that by now, you’ve decided on the Raspberry Pi model. The next step is installing the OS and getting started with your Raspberry Pi PC.

Which Operating Systems Can You Install on Raspberry Pi?

If you have a Windows or MacOS background and haven’t used a Raspberry Pi before, you may need to change your habits, as neither system is suited to it.

In short, Raspberry Pi is designed to run Linux distributions, specifically Raspberry Pi OS, the official distribution based on Debian and developed by the manufacturer. While you can install another OS such as Windows 11, the performance will be disappointing, no matter which Raspberry Pi model you use.

That doesn’t mean you don’t have a choice. There are many Linux distributions available, all with different flavors to suit your preferences. You might even get lost wondering which one to choose, so let me guide you.

For a PC set up, I recommend the official Raspberry Pi OS. Raspberry Pi OS is the Linux distribution created by the Raspberry Pi manufacturer. It’s built to be compatible with all Raspberry Pi models and includes the essential applications to get started with this tiny computer.

If you’re starting out, we have plenty of posts on this website covering Raspberry Pi OS, from what it is to detailed installation guides. Here are a few you might find useful:

• Install Raspberry Pi OS Bookworm on Raspberry Pi (Illustrated Guide)
• What Is Raspberry Pi OS? (Goal, Installation & Benefits)

And if you’re already familiar with Linux systems or feel like exploring beyond Raspberry Pi OS, there are several other distributions you can try, such as Ubuntu, Manjaro, and Fedora. For a deeper dive into these options, check out the Best Operating Systems for Raspberry Pi.

Note: I have a video available for community members where I introduce the best distros for desktop usage (so you don’t have to test them yourself). Join here to watch, and get access to 30+ other lessons for Raspberry Pi!

Installing an Operating System on Raspberry Pi

Installing an operating system on the Raspberry Pi is different than on your normal PC.

In most cases, traditional computers have Windows preinstalled, so you don’t need to worry about the installation. And if you do, you usually create a bootable USB drive and use it to install the operating system to the internal storage.

With a Raspberry Pi, the internal storage is a microSD card. To install the OS, you simply make the microSD card bootable using tools like Raspberry Pi Imager. These tools allow you to flash the operating system image onto the card, making it ready for the Raspberry Pi to boot directly into the new OS.

You can follow our comprehensive guide on how to install or re-install the Raspberry Pi OS on the Pi for a step-by-step guide.

The minimum hardware requirements you will need to set up your Raspberry Pi PC include:

• A Raspberry Pi board. For this project, I recommend using the models that I listed above. Typically, a Raspberry Pi 5 would be perfect.
  
• A microSD card (at least 16GB) for the operating system. Please don’t just pick up any SD Card. Some are not of good quality and the Raspberry Pi might not boot. You can check our post on the best Micro SD Card for the Raspberry Pi for an in-depth guide.
  
  If you want more storage, you can also boot the Raspberry Pi from an SSD instead of using an SD Card.
  
• The official power supply from Raspberry Pi. Our article on how to power a Raspberry Pi will give you tips on the advantages of using the right power supply. In case of any issues with the power supply, we also have a troubleshooting post like how to avoid “Under-voltage Detected” errors on Raspberry Pi.
  
• A keyboard, mouse, and monitor for input and display. Here are my favorite keyboards for the Raspberry Pi, but any USB model you already have can be used.

Customizing Your Raspberry Pi System

After installation, you might want to personalize the system to your liking.

The first thing you can start with is changing the default desktop appearance. That’s not because the default appearance isn’t appealing, but as you might understand, the Raspberry Pi OS is built for beginners. With that in mind, developers try to keep things clean and simple which might be less exciting to many.

Then you can start by installing additional applications on the Raspberry Pi. Like any other operating system, Raspberry Pi OS comes with many default applications. However, you can install more using Snap or the APT package manager.

It’s also possible to adjust the system settings and configurations to tailor your Raspberry Pi to your needs. If you have a desktop environment installed, you’ll probably use the GUI, or you can also use the Raspi-Config command-line utility. It is a powerful utility that provides a text menu, so you can modify both hardware and software settings for your Pi all in one place.

What Can You Do with the Raspberry Pi PC?

Now that the hardware and software parts are taken care of, you can do a lot with the Raspberry Pi PC that you would still be able to do on your regular PC. Here are some examples:

• Programming.
  
  The Raspberry Pi is a fantastic tool for learning and practicing programming. It supports multiple languages, including Python, Java, and C++, and comes preloaded with tools like Thonny IDE. You can also install other popular IDEs like Visual Studio Code.
  
  If you want to become a pro Python developer with the Raspberry Pi you can get our Master Python on Raspberry Pi e-book. This book is for any Raspberry Pi user who wants to spend the least time possible on theory and go straight to the real-life usage of Python.
  
• Web browsing and social media.
  
  The official Raspberry Pi OS has a lightweight web browser known as Chromium, which you can use for basic web browsing and staying connected on social media. However, that doesn’t mean you cannot install any other browsers.
  
  Our article on the Best Web Browsers to Use on Raspberry Pi lists the 5 best browsers we tested, providing detailed insights on their performance, features, and usability.
  
  While most of these browsers can handle multiple tabs, it’s best to avoid loading too many resource-heavy websites at once for a smoother experience.
  
  If you installed an operating system like Ubuntu, you can check our post on the top 5 browsers you can install on your Ubuntu system. These browsers have been tested for speed, features and more.
  
  Here are some other articles that might come in handy for installing different browsers on your Raspberry Pi:
  • How to install Brave Browser on your Raspberry Pi.
  • How to install Tor Browser on the Raspberry Pi.
  • How to Install Firefox on Raspberry Pi? (Latest Version)
    
• Watching videos and listening to music.
  
  The Raspberry Pi can stream videos on YouTube, Netflix, or other platforms and handle music playback seamlessly. It supports up to 4K resolution (on compatible models like the Pi 4), making it a budget-friendly option for casual media consumption.
  
  
• Basic productivity.
  
  You can use office software like LibreOffice to create and edit documents, spreadsheets, and presentations. It’s sufficient for light productivity tasks but may struggle with large or complex files.

Warning: While the Raspberry Pi can do many things, it has its limitations. Due to its limited processing power and GPU, it isn’t ideal for heavy video editing, 3D rendering, or playing resource-intensive games due.

Many applications are also not available on Linux systems. For these tasks, a traditional PC or dedicated hardware would be more appropriate.

Common Challenges and How to Solve Them

Deciding to use the Raspberry Pi as your PC comes with a few challenges, unlike when you are using it for other tasks like testing out some IoT projects. Let’s look at some of the most common.

Portecting the Raspberry Pi from Damage

The first thing you’ll need is a Raspberry Pi case—you can’t just leave the bare board lying on your desk, exposed to dust or the risk of accidental contact with liquids. A good case not only protects your Raspberry Pi but also helps with cooling and stability.

That’s why we created a detailed guide on finding the best case for your Raspberry Pi. This article covers important factors to consider when choosing a case, helping you pick the right one to keep your board safe and functional.

Managing Heat to Prevent Performance Issues

When using the Raspberry Pi as a PC, you’ll likely run more tasks than usual, which will cause the board to generate more heat. If this heat isn’t managed properly, it can lead to thermal throttling, where the system slows down to prevent overheating.

Fortunately, there are several cooling solutions you can implement to maintain optimal performance:

• Installing Heat Sinks: Heat sinks are small metal plates that attach to key components like the CPU and GPU. They help dissipate heat more effectively by increasing the surface area, allowing for better cooling. This is a simple and affordable way to reduce heat buildup.
  
• Using a Heat Sink Case: Another option is to use a case designed to act as a large heat sink. These cases are typically made of aluminum or other heat-conductive materials and provide passive cooling by transferring heat from the board to the case’s exterior.
  
• Adding a Cooling Fan: For even better heat management, use a case with a built-in cooling fan or add one separately.

Lastly, ensure you have a good backup process in place if you spend time setting everything up. You don’t want to lose your data or have to start over a few weeks later because of a wrong move.

Going Beyond: Expanding Your Raspberry Pi Experience

Once your Raspberry Pi PC is up and running, there’s plenty more you can do to enhance its functionality and performance. Here are a few ways to take your Raspberry Pi experience to the next level:

Adding Optional Accessories

While the Raspberry Pi can function well with basic hardware, adding optional accessories can greatly improve your experience.

• External SSD: Upgrading from a microSD card to an external SSD significantly improves read/write speeds, resulting in faster boot times and better overall performance.
• Peripherals: Accessories like wireless keyboards, mice, and game controllers can add convenience, especially if you’re using the Raspberry Pi for multimedia or retro gaming.

You can find my current gear recommendations on this page for a complete overview.

Overclocking for Better Performance

If you want to push your Raspberry Pi to its limits, overclocking is an option. Overclocking increases the CPU and GPU clock speeds, resulting in faster performance for tasks like web browsing, media playback, and emulation gaming performance.

You can overclock by editing the config.txt file on your Raspberry Pi and increasing the clock speed values. If you have never overclocked your Raspberry Pi before, you can check out our post on tips & tricks to increase your Raspberry Pi’s speed.

Tip: Overclocking generates more heat and may reduce the lifespan of your device, so it’s essential to have proper cooling in place, like heat sinks and a fan, to prevent overheating.
