FYI, 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. http://www.tyan.com/products/html/gx28b2881.html If you are in the US, you can get it for about $900.00 from a reputable vendor. http://www.newegg.com/Product/Product.asp?Item=N82E16856152009 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): http://www.supermicro.com/products/chassis/3U/932/SC932T-R760.cfm I also have two of these servers running drbd with 15 SATA150 250GB drives. DRBD works perfectly as well. Diego 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 Eugen Leitl wrote: > On Tue, May 23, 2006 at 06:32:00PM +0200, Helmut Wollmersdorfer wrote: > >>Eugen Leitl wrote: >> >> >>>P.S.
