Well, another reason to build your own. Check what motherboard comes w/ it, and post it on here. You want a MoBo w/ good OC options in BIOS. And btw, to overclock .5Ghz, you're gonna need some damn good cooling.
if ur neighboor bought the pc from compaq you won't be able to overclock at all, its an oem motherboard (original equipment manufacturer), they lock everything in the bios becuase the computer is usually under waranty and if they didnt lock it you would be able to overclock and risk frying ur cpu, then the company (in this case compaq) would have to supply you with a new cpu.

Honestly, I have never heard of Cyber Power Systems. I doubt they have many OC options, if at all. Better off building one. If you do decide to get one, you can overclock by 200mhz or so. Just watch temps and voltage.
