P.S. if you do build a computer, look to build with a Corsair cases. I've used 2 and they are really nice
I'll +1 this.
When building a PC, don't cheap out on
- case / PSU
- motherboard
- ram
crap motherboard = driver/bios/support problems, and a crappy chipset will cause stability issues.
crap case = you'll cut yourself, have issues routing cables and if it flexes it can cause the board to have problems.
dodgy ram is THE number one cause of PC crashes nowadays.
the case is easy to forget - "it's just a box!"
but working on a machine in a crappy case is just really annoying.
