I haven't read all the posts in this thread so please excuse me if
this has been offered before...
A fairly simple and upgradable high density server can be built using
the following components....
Coolermaster Stacker Case (I'm not sure of the later versions but the
801 original version had 12 5.25" bays if you removed the front USB
2 x 600w PSU's for load spreading
1 x Asus P5WDG2 Mobo - Supports PCI-X but is a workstation class board
so doesn't need ECC ram.
Up to 4 x Supermicro CSE-M35T Sata Chassis (each one takes up to 5 3.5" Drives)
Areca SATA Controller (Various options to suit)
Whatever Processor and Memory you feel is required.
The Mobo's are pretty rock solid and just run without fuss, the sata
chassis have fans and temp management so again pretty much just run.
