How to make a custom PC case


Making a custom PC case comes with a lot of failures. Yes, I said failure. From the review I got from other people who have been able to design their custom PC cases, they spoke about the number of times where they failed and had to start all over again. So, don’t come here thinking ‘oh after reading this blog post I will just magically build my custom PC case’. It won’t work like that. This blog post will only help to guide you through the process of making it. The amount of hard work and determination in getting it done is up to you.

However, don’t be discouraged. You can still make it too. All you’ve got to do is pay close attention while reading all the informative things packed in this article. I haven’t made one myself, but I’ve got a list of dos and don’ts that will help you in making your custom PC faster with minimal errors that will help prevent failure. The goal of this article is to minimize the chance of you failing and having to start all over again. I want you to get it right at your first trial. With all these being said, let’s get right into it!.

1. The first step in making a custom PC case is: Having a design.

Do you have a design in mind?. What would you like your PC case to look like?. This is the first step in making a custom PC case. You have to know what you want your PC case to look like. So if you haven’t done this, hurry up and go get it done. Because without having a design in mind, you won’t be able to properly carry out what you’ve got in mind, thereby putting your ability to work on it till it becomes realistic, on hold.

Creating a design can be very tasking because you have to get it right. The design of your PC case greatly determines how your PC case will come out looking. So you have to take your time in calculating and measuring everything to perfection.

Tip- If you are through with your design, you can send it out to manufacturing companies for review. If you are skeptical about taking that bold step, just forward it to a friend or family member who has an idea about manufacturing design. Calculate your bends, holes, and sheet thickness well before sending the copy of your design out. Make sure it’s error-free.

2. Building a Preliminary Prototype Of Your Design

If you get feedback from the family, friends, and company you sent your designs to, incorporate that feedback into your work by having a preliminary prototype of your design. Test your designs by using your metal sheets.

3. Start building your design

The next step is starting to build your design since you are now armed with physical intuition from building the pre-prototype. Begin doing round and round of design improvements.

Since it’s a custom PC case, you will have to try as much as possible to limit your expenses. Unless you have enough money laid down to get it done. But if you don’t, keep in mind that as much as you want the case to hold as many combinations of components, focus on making the case as quick and cheap to construct as possible.

This might include making certain decisions like:

  • Having a limited bend as possible.
  • Make the case be built from bent metal sheets without any necessity for wielding.
  • Reduce the quantity of punched holes, rather than enhancing the hole size to retain the same hole size to maintain the same total hole area.
  • Limit the number of openings that can not be made by punching holes (must be laser cut).
  • Make use of only one hole size, so the hole-punching tool does not have to be swapped out during the whole process.

4. At this stage the design case should be almost conceived

After many iterations, the design should be able to hold at least 2-4 different configurations, including a water cooler, a full-size GPU, and a large 3.5 hard drive. If it does, then your flat case design is coming up well.

5. Manufacture your designed prototype.

It’s time to manufacture your design. Start building the design you want to bring to life. However, if you can’t DIY (do it yourself), Send a manufacturer your design and tell him all he needs to know and how you want your prototype to be made.

6. Test run your prototype

Now, it is time to test-run your finished prototype. The tests to run and things to check are thermal tests, structural tests, and component fitment.

If you are not satisfied with what you have, you can tweak some details and create a second prototype.


Keep tweaking and going over every detail of your prototype till you create that perfect custom PC case. Like I said earlier, the creative process isn’t easy. You’ve got to put in the effort, plan appropriately and make multiple calculations till you get it right. There’s truly no need to be upset if you don’t get it right. If you don’t get it right immediately, you will get it right eventually. Moreover, we all learn from our mistakes. And DIY (do it yourself) projects sometimes aren’t simple to do. If you don’t get it right the first time, you can try again till you do. At the end of it all, it will be worth it. I hope this article will be of help to you, but if it doesn’t, maybe you should go for more practical tutorials. Maybe go on YouTube and check out the videos there. Maybe, just maybe, it will help you. Or better still, you can incorporate the two (this article and the videos), after all, there’s nothing like excessive knowledge. Keep up with your journey and don’t give up!.
