OK, this is what I used for a bunch of systems: Two of these CPUs: http://www.amdcompare.com/us-en/opteron/details.aspx?opn=OSK248FAA5BL 2.2GHz low power Opterons This motherboard: http://www.tyan.com/products/html/thunderk8w.html I may go with a different one for the dual core units because the users want PCI-Express video cards now This RAM: http://www.ec.kingston.com/ecom/configurator_new/partsinfo.asp?ktcpartno=KVR 333D4R25/2G Usually a full 16GB. This case: http://www.chenbro.com.tw/usa/product/product_preview.php?pid=134 with the SCSI hot swap backplane. Remove the rear fan because it sounds like a jet engine. This RAID controller: http://www.lsilogic.com/products/megaraid/scsi_320_1.html These CPU coolers: http://www.zalmanusa.com/ -- search for CNPS7000B-Cu This 460 watt power supply: http://www.quietpcusa.com/acb/showdetl.cfm?&DID=8&Product_ID=30&CATID=2 -- wonderful and close to dead silent This case fan: http://www.quietpcusa.com/acb/showdetl.cfm?&DID=8&Product_ID=261&CATID=7 -- the 120mm one, in the Chenbro bracket that came from Chenbro with a fan that would be right at home in a small helicopter. At the lowest setting, you really have a hard time hearing it.
Disks varied, as did video cards. For the next bunch, I may use a slightly different Tyan board, but I am not sure yet. With the dual core AMD CPUs ( http://www.amdcompare.com/us-en/opteron/details.aspx?opn=OSK275FAA6CB ) and the Zalman CPU sink CPNS9500, ideally without those silly LEDs. Something nice that I have found makes the users happy is this: http://www.mitsumi.com/products/fa402amain.html Instead of a regular floppy, they have a media reader for stuff. Happy to answer any questions.

I'd like to use some nice CPU coolers (like the Zalman ones) and one concern with going ATX (like the Master) in addition to the RAM issue pointed out previously is that with the smaller form factor you often don't have the real estate for efficient coolers. Thanks again, Peter Quoting Paul Brook: > I've got a largeish EATX thermaltake xaser3 case (next size up from > standard midi towers), Tagan PSU, Zalman CPU coolers and a Tyan S2885 > motherboard (though the S2895 is probably a better bet for new > systems). > > The CPU fans are temperature controlled by the motherboard (and rarely > get above 50% speed) and the case fans are on a fixed 40% speed > controller. > > It's not totally silent, but it is quiet even under heavy load.
