So i've currently been running the following system:

1.6ghz Intel Atom
Micro Itx Mobo which has the cpu integrated on
2gb DDR2 533mhz
320GB Seagate S3 7200RPM HDD
All in a M-100 Micro Itx Case w/ 250w PSU

Biggest waste of money, slow as F. So I bought a pci x1300 for it, which was then bottlenecked as bad as the onboard from the psu. This was in WoW, simple stuff like internet, and music, and non HD movies works fine.

Anyways so last week I ordered an x2 5000+, and a Asus M2A-VM mobo. I plan on getting a normal case and psu and sticking everything in it.

If anyone wants to buy the current case,mobo,cpu,pci x1300 pm me

Is that one of those Eee boxes?

Nope, basically a fancier once, not as small.

UPDATE: Ordered a Antec 300 & a 500W CoolerMaster StealthStream!

Problem I had with the antec 900 even is cramming stuff into it. Youll end up cutting or moving fans etc when it comes to a 9800 and such.

Other than that you should be good!
