So ive bought a computer ( HP 500-326na if you must know) I'm hoping to change stuff around, mod it a bit and stuff along the lines of that over the next few months, i was originally planning to build a desktop... but i had no idea where to start. Until i found here and already have my desktop, so anyways.. if i were to change the CPU? GPU? Mod it out a bit, would liquid cooling be something i could do in this case? or would a new case be required? Thanks alot guys!
