Would I be able to buy current computer hardware and mod the hell out of it? I.e. overclocking through the BIOS, but if that ain't enough would I be able to tweak the hardware to make it run even faster? Without going insane (no liquid nitrogen!) What other kinds of tinkering can I do with the hardware as a hobbyist? Would I be able to design my own modchip for an Xbox 360? How about replacing my xbox 360's GPU with a more powerful one? (I read the PS3's GPU power is equivalent to a Geforce 7800GTX, not sure about the 360) That would be awesome if I could do that.
