I'll teach you how to build your own. I've been building my own PCs/PCs for my moms cilents for 4 or so years now. Its really just like a big lego set....a lego set that you can fry with a little static electricity. But for about a grand you can build a decent gaming class pc. Something that would cost around 2K from dell/alienware/ect.
