I'm kicking around the idea of upgrading mine, but then I think just selling it out right and buying the case, drives, etc. instead.
It has a Q6600 with 4 GB ram. It had 2 8800GTs in SLI but one of the cards crapped out. It would not come with a hard drive, but would come with all of the disks. Has XP Pro and Vista Ultimate 64 bit disks.
I'll let you know what I'm doing ASAP.
