ComplexGames is moving back downtown and has some 1U dell's they'd really like to not move.
They have PE850's ($75) and PE860's ($100) and they should even have the rails with them (at least that's what I remembered when I last saw them). They probably won't come with the gray Dell cover bezel (I don't remember seeing them last I was there).
The PE850s (and the 860 with the Xeon 3060) are most likely SATA disks and the 860's most likely SAS disks (though SATA 'should be compatible' if the drive has the same part positioning on the drive carrier).
If you would like one, two or all then give noah@complexgames.com a shout.

These are a great price for a 1U machine (I'm grabbing an 860 for myself, not included in the list below).
Feel free to forward to anyone you think may be interested (posting to these groups first due to density of interested parties).
