Very nice work man! That is my kind of setup, super clean, and simple... keep it that way.
If you want a new computer, build one your self and 'overclock' it, you can get a ~$150 cpu @ 2.13ghz Core 2 Duo and get +3.6ghz from it, these chips are blazing fast.

I am going to be taking my brother's sony Viao because he is going off to college, but I am just using that as the base. I still want to upgrade it for my needs. Where could I get that $150 CPU? I am planning on having 1.5TB(3-500GB hard drives) in the set up when I am done.

Overclocking is pretty simple. You just go into the BIOS. You will have to do something for the heatsinks though. It will likely get a little hot if you don't get a bigger heatsink and/or fans at the least. As far as RAM, ZPB is right. You will likely need to upgrade it because alot of computers still have 184 pin RAM and alot of the new motherboards are using 240 pin. I discovered this a few months ago when I built mine. Personally, I like AMD's. I have a AMD Athlong X2 4200+, probably gonna be the 6000+ soon. I'm pretty happy with it. I would go with 2 gigs of RAM or so. I have 1 gig right now, and my Alienware Dock says I'm using half that or so, and I don't have a bunch of programs or anything on my computer that I use.
