Desktop PC Cases come in various shapes and sizes. Two of the most important factors to consider when searching for a Desktop PC case should be the size of the components that you'll install within the case, as well as whether you should leave room for future upgrades. Since you'll need to know the size of the case, you'll need to know which hardware pieces you're going to use before you buy the case. That way, you won't be faced with the possibility of having to return the case when everything won't fit inside.
Next, consider how many bays you'd like to have in the case. Desktop PC Cases come in varying sizes and number of bays. If you don't know what you'll need before you select a case, this can result in a major headache. I doubt many readers still use a floppy drive, but if you're the old-school type then be sure your PC case includes a 3.5" floppy drive. If you want more than one hard drive, you should get a case with many 3.5" bays, as that's the size used by hard drives. CD and DVD drives require 5" bays.
Just like Desktop PC cases, motherboards are also produced in different sizes, so you'll need to ensure that it is compatible with your case. Luckily, it's easy to match up your case and your motherboard. Both components are labelled with a "form factor," or sizing standard. You're likely to see "ATX" for the identifier. This is the most common size. Do yourself a favor and open up all options available to you by beginning with selecting a motherboard with ATX form factor. You'll thank yourself when you start shopping for PC cases and discover that the majority have ATX form factor.
Select a Power Supply
The power supply is a crucial component for your computer, especially if you plan to build a gaming rig. If you're going to be using your computer for gaming, you should select a power supply that outputs at least 500 watts. Many gaming computers may not even be satisfied with 500 watts. If your components are high-performance, they probably demand a lot of electricity as well.
While many cases are shipped with a standard, stock power supply, I recommend that you buy a different one. Remember that you get what you pay for. So a free power supply is not going to satisfy you. Power supplies that come with PC cases generally mean that they are cheap. Gaming PCs need power to boost that framerate, so give your computer what it needs and it will perform for you when you are in the heat of battle!
Keep it Cool
Another important factor to consider is how you'll keep your expensive components cool. High-performance components can only maintain high-performance output if they are kept at optimum temperatures. And generally, the cooler the better. Aside from just drops in performance, overheating can cause damage to your monster machine. It's important to keep good air circulation going in your PC. So don't select a PC case unless it's got at least 2 fans. Heat sinks and liquid cooling mechanisms are becoming more and more popular.
Personalize Your Case
For many folks, it's important to make their PC look cool. Acrylic cases are becoming wildly popular because they are clear, so you can see right into the computer. It just might give you that extra push to take your gaming to the next level! If you've managed to save some of your budget by finding deals elsewhere, then consider spending the rest on making your case look good! But if you don't care so much about how it looks, then you might prefer spending any leftover cash on upgrading your other components.
