I'll soon lose a place to keep my Dell 7400 Workstation, probably by the end of June. I've got about $300 into it, including memory and CPU upgrades. This has been a great cruncher; it's solid on CPU projects and has two PCIx 2.0 x16 slots for GPUs. In just under a year it's earned over 115 Million in credits with various gpus. Caveats: it's a big box, is a bit on the loud side and is HEAVY.
I wish I could give this away, but unfortunately I need to recover some of the costs. On ebay these are going for $250-400 and higher. I'd like $200 plus shipping (likely to be $50+). If there are no team takers after a few weeks, I'll put it on craigslist/ebay.
Here are the specs:
Dell T7400 Precision Workstation
Dual Xeon Quad Core E5450 3.0Ghz 12MB L2 1333Mhz FSB
16Gb PC2-5300 667MHz RAM (recently purchased new)
74Gb 10k RPM SATA Western Digital HD or 250Gb SATA HD
Windows Vista Business x64
1000W PSU
I can ship with no GPU or one of the following:
AMD HD 6570 $25
AMD HD 6950 $65
Nvidia GTX 580 $100
AMD HD 7950 $125
