For server boards, Tyan and Supermicro - be aware though that some
Supermicro boards are designed to only fit in SM chassis. There are
many options for SM, the simplest may be to buy an SM barebones system
and then add CPU/RAM/controller/disks.

Supermicro P8SCi perhaps, with the new 3ware 9550SX controller, I've
also been reading good things about the Areca controllers.

3ware 7/8/9xxx supported on 4.x/5.x/6.x and work well.
Areca controllers are supposed to be very good performance in RAID5 but
I don't think the drivers are in the CVS/release branches (yet?), so
some manual integration is required.
Also make sure you use the right disks, I've only recently realised that
most PATA/SATA disks are manufactured to spec for a "8-5" desktop usage
pattern, and you should really use the 24x7 certified models in servers.
Although there is a bit of a conflict here as I'm not sure any of the
24x7 rated drives are SATA300 capable at present.

Generally speaking, they make desktop boards (I say generally because
some do have separate ranges of higher priced server boards) - the
difference between desktop and server boards can be important when
you actually look more closely:
* Poor chipsets - don't really want Realtek ethernet?
* Limited RAM slots / maximum RAM
* No ECC RAM support
* No 64-bit PCI - want to drive your RAID card properly?
* Not enough dedicated bus bandwidth - ethernet, PCI, video, etc
