I can build my own but you can't beat the prices on many pre-built machines.
actually it is VERY easy to beat the price on a pre-built, and to top it off you'll know quality parts are going into it not just whatever they could get the cheapest of.
4GB is the base these days, and ONLY go 64 bit OS. 32 bit is dead.
