Holy crap I need to get rid of this. It's an old Dell Dimension E520 with a couple changes.
Intel Core 2 Duo E6300. 1.86 GHz of hot hot processing action.
4GB DDR2 RAM, 667mhz.
ASUS Geforce 9600 GSO, 512MB. Can play most Source games on medium.
250GB 7200RPM. Think of it like a SSD, but not.
Rosewill B/G/N Wi-fi card.
I've run Ubuntu and Win7 on it with no major issues.
Looking for about $125 or OBO. Come pick it up around the 181/190th Street A station.
