Ok, so I have my parts, but I don't know how to build, and I don't want to risk it by building it by myself (I'm not really good at building stuff). Is there a company that could just put my parts together?
If I summarized what you need to build one it really isn't very complicated
1.Install motherboard
2.Install power supply
3.Install hard drive
4.Install RAM sticks into the slots
5.Insert the CMOS battery in your motherboard if it doesn't have one
6.Install the CD drive
Cd drive, power supply, and the hard drive have connectors that run to the device and to a slot in the motherboard
