Having a powerful PC is a great experience. This is true for gamers and professionals alike. Gamers want a big PC that can hold all the highest quality components and run new games well. Professionals need something that can run all their programs flawlessly to maximize workflow. One issue that both experience is a lack of desk space to hold their computers as they increase in size. To fix this, a unique option is the under-desk computer case mount.

What is an under desk computer case mount?

An under-desk computer case mount is a mount that holds your entire computer case under your desk. They have a design that holds it vertically and out of the way.

How do they attach?

These devices are attached to the bottom of your desk via screws, typically. Most have a bracket you attach to the desk with four screws, and then a strong bolt secures the bracket to the mount surrounding your computer.

Will an under desk case mount hold a heavy computer?

Yes, it really will. These mounts are designed to hold up even the most modern and bulky computers out there. That said, it’s always important to check the weight capacity of any bracket before actually buying one. Compare that with your computer weight and make absolutely sure that it will work.

Will it cause cooling issues?

They could, but they probably won’t. These brackets are designed to hold the computer upright, just as if it were standing on top of your desk. The only way it could have any issues is if you have a ton of air intake through the top of your case. Even still, very little of it will ever be completely covered, so you probably won’t have any noticeable issues.

Are there any features to look out for?

Yes, there are some features you should pay attention to. The first is the actual design and aesthetics. A good mount needs to either blend in or complement your PC build. Otherwise, it will stick out like a sore thumb. Next is PC compatibility and strength. Knowing how big your PC is (dimensions and weight) is crucial to make sure that it will actually work to hold up your computer. Next, check out how hard it will be to set it up and attach it to your desk. Finally, see if there are any specific differentiating bonuses that you can find that may make you want one over another when making a buying decision.
