The Case.

The Case is where all the components are stored like the motherboard; optical drives PSU and hard drive. It’s important that the case looks nice so you feel better using the PC. The most common case is micro ATX or mATX. The largest case it ATX. ATX has more expansion bays than mATX. The USB and Audio connections go onto motherboard by 6” long cables. The lights and buttons connect to the motherboard too (see motherboard manual). The hard drive goes under the floppy drive slot. ATX cases have lots more spaces for hard drives, while mATX has 2-3 ATX has up to 9. So if your are going to use it as a PVR or server then a ATX case is better for you. An ATX case can also fit in any motherboard. But if you are short on space then a Micro ATX case will be better for you.
