FWIW, I've built one of those SuperMicro machines, with eight drives, around the beginning of the year. Allowing for redundancy (RAID 5 on six disks for data, and mirrored the boot drives), we ended up with 6.5TB of storage at about $3500 (that includes i7 proc and 12Gb RAM, and a fancy controller). My labor added some more on top of the $3500. Mostly, we've been happy. It is more sensitive to heat issues than our HP G5s, and of course, generates more of that heat. If I were to go with any kind of density, I'd need a much more robust cooling solution.

Yep, that spec would be over the top for a storage node, though. A large chunk likely went into the controller and the i7 whereas in a storage-node most cheapo controllers (i.e. 2x8 is cheaper than 1x16) and whatever old xeon/core2 will do. Wrt cooling, for actual servers (i.e. not storage nodes) we've had good success with Sun XFires, the 4100+ range. They are very well built and the markup over the SuperMicro junk is minimal (around 15% last time I checked). Among the niceties is a nice array of hot-swap fans - something that SuperMicro still doesn't seem to deliver in their popular chassis. I'd also consider the xfires for storage nodes if they'd take 3,5" drives, but afaik all their low-end models only have max eight 2,5" slots. That's just no worthwhile density when compared to the larger SuperMicro tins (which go up to 30x3,5" now I think).

  Most of the money went to the hard drives themselves. They've come down a lot since (1.5TB had just been announced), but it was around 70% of the cost. Everything else was relatively cheap. The 2.5 drives are good, and seem to becoming typical, because they run much cooler. We've got some G5s in the same closet, with just as many drives, and they don't run nearly as warm.

  I second the 4100s. I had one on a loaner program, and they are sweet machines.
