The Tyan 1U barebones servers are quite nice. I have put together several of these and like them a 
lot. You can fit 4 SATA hard drives (hot swappable). The temperature on the drives is usually around 
31 Celsius in a properly cooled server room.


If you are in the US, you can get it for about $900.00 from a reputable vendor.
As usual, try froogle.google.com or pricewatch.com or your favorite price engine first to get the 
best price.

I have some of those chassis with ARECA ARC-1110 (including battery) cards doing DRBD. Pretty cool 
systems which I put together for ~$2850 each with Dual core Opterons 270s, 4 GB RAM and 4 SATA II 
250GB drives.

If you need more space then use the 3U supermicro cases (the ones in black are pretty):


I also have two of these servers running drbd with 15 SATA150 250GB drives. DRBD works perfectly as 


PS. Recipee for a 10.5 TB file server for under $11,000 (Get 2 and DRBD!)
Drives           $7,500 (15 Seagate 750GB SATA drives)
Chassis          $1,000 (Supermicro SC933T-R760)
Raid Card        $1,200 (Areca ARC-1160 Including battery)
Mobo             $  400 (Tyan S2881)
CPUs             $  360 (2 Opteron 246, Add faster processors only if really needed)
RAM              $  450 (4 GB Corsair DDR400 ECC Registered Ram)
Total           $10,910
