Desktop PC case parts guide: which parts to use for your desktop PC case

Desktop PC cases give you a clean, modern aesthetic that allows you to showcase your PC’s internal engineering. Why not turn your PC into a desk to free up space on your desk without leaving your PC on the floor?

Rather than buying an expensive desktop computer case, you might be considering making your own. Here are some parts you would need to get started.


Before you start building a desk that can hold the components of a PC, you will need to decide on the specifications of your design. Whether you are working with wood or metal, the size and shape of your desk and the tools and space you have access to are good things to consider when you start designing.

This article aims to find everything you will need before you embark on your journey to beautiful and functional computing equipment. Of course, the supplies you need will be determined by your design specifications, but this guide can help you find the items you need to make your designs a reality.

Use of pre-existing office rooms

If you are looking to avoid the high costs of a prefabricated desktop PC case, you can try to save money by converting a cheaper desktop to a desktop PC case. Buy a desk in a style you like and only keep the parts you don’t want to have to build from scratch.

You can find legs or stands at Ikea or a complete desk kit at Amazon, another big box store, or even buy a used desk that’s easy to take apart. Then you will have an easier time building a PC case to fit the brackets you have available.

If you shop around enough, you may be able to Frankenstein the parts of old desks into an office to build your PC. You can look for an ornate wooden base and attach it to a glass and steel frame to combine styles. You can also find all the aluminum, steel and glass you need to create a sleek and modern office.

DIY PC Desktop

Building a PC desktop from scratch can be expensive and time consuming, but it will ensure that you get exactly the desk case you imagine. This can allow you to bypass the size constraints of your gaming space or help you fully achieve your ideal gaming aesthetic.

Decide if the enclosure will be all wood, metal, or a mixture of the two. Most computer cases and many computer desks are made of galvanized steel or aluminum. Steel and aluminum can be cut to specific sizes.

Contact a local custom metalworker or carpenter if you can’t find a PC case online and don’t have the tools to realize your vision. They may be able to make the pieces to assemble or help you build your dream desktop case.

Essential supplies for any desktop computer case

Motherboard spacers

Motherboard standoffs are metal standoffs that separate your motherboard and your PC case. The motherboard is one of the most critical components in any PC. Having quality motherboard spacers ensures that your motherboard can regulate power to your PC.

Cable routing channels

Cable routing channels help keep the interior of your PC case clean and organized. Channels serve to protect your PC cables from heat and stress by keeping them away from components that heat up.

Anti-sag stiffener

Sometimes a solid rod of dense metal is attached under a PC case to evenly support the weight of the PC. Aluminum and wood are malleable and can be heat sensitive. The PC desktop cases that are built with them can be supported by an anti-sag steel bracket to keep your PC desktop strong. Some desktop frames are constructed entirely from steel, so a large sheet of steel can be used to form the bottom of your desktop computer case.

Heat-tempered glass

A common and perhaps the nicest part of a PC desk is a glass surface that allows you to see the fans whirring while you bask in the glow of RGB RAM cards. It’s easy to order tempered glass sheets or purchase one in a custom size from a local glassmaker.

Tempered glass is strong – it can withstand a lot of weight and withstand a considerable amount of heat. This combination makes it perfect for use as a desktop computer. If you don’t have access to a glassmaker, you can find a desk that already has a glass top and build a PC case for the size of the glass desk. You can also use it for the front and sides of your desktop case to show off its internal engineering.

Fans and fan control

Fans are an important part of the proper functioning of any PC case. The additional measurement of the fan control software, or a manual fan control monitor, can give you an accurate reading of the ambient temperature of your desktop computer, let you quickly read the power consumption of CPU and GPU, and let you control the speed of each fan.

3D printer

3D printers will allow you to create some of the parts you might need to finalize your custom PC case design. If you have access to a 3D printer, think about how you could use it to make the parts you need for your custom desktop PC case design.

Print external edits with designs that will help you achieve the aesthetic of your PC case or organize the internal structure of the office. You can print parts like fan brackets or even a cable routing solution.


The type of tools you will need to build your desktop computer case will be determined by the materials you plan to use to build the case and its design specifications. If you already have the tool, skills, and space to work with wood or metal, take this into account when creating your design.

Get good safety gear, a pair of eye protection, and non-conductive gloves to protect yourself while you build.

A drill and a set of ratchets or screwdrivers will be needed, especially if you are working with wood. Wood glue, pliers and a saw will allow you to cut planks to the exact specifications of your design.

A portable CNC allows you to shave and shape wood or metal and would be a useful tool for complex custom designs. It also allows you to punch holes in your PC case for ventilation.

If you are working with steel or aluminum, a rivet gun will allow you to make strong connections between the metal brackets of your desktop PC case. A soldering gun for creating conductive attachments in the PC is another necessary tool.
