YOUR SO LUCKY!!!! I wanted to build my own pc too (i'm 13 also), but my dad said "it's too risky" "what if something goes wrong" "we'll lose all that money if you break it". I got an e-machines with a radeon express mobo, and an amd athlon 3200+ (winchester). I put in a 6600GT, zalman vf700-CU, sound blaster audigy 2 zs, a floppy drive (which took considerable case modding), and a hard drive fan (more case modding). And it turns out the 300W power supply which came with the computer isn't really strong enough do drive all that. So I told my dad that if I got a new power supply, I would need a new case to fit it in (the case is mATX). But then, that might not fix the problem because the CPU fan is really cheap, and that could be what is crashing it. After two months of this, my dad said I could build my next computer, in 2 years. Oh well, That will be around vista time so I suppose it won't be all that bad. Nice rig man, and congrats.
