This has been discussed here many times. Hot-fix IS possible with
software raid, please read the archive of this list where I posted the
list of commands. And please, don't go again in a war between software
and hardware raid, it's ridiculous. Use what you feel is right, and let
the other use what they like...

Wrong, SATA2 do accept hotswap, we did it many times.

Where exactly did you see that SCSI and SATA have different internal
mechanic? I really don't think this is the case. I would rather advise
somebody to use the seagate -NG series that have longer MTBF.

At GPLHost, we are VERY happy with the Supermicro PDSME or PDSMU (nearly
same board, one have 3 more PCI slots that we anyway don't use). They
support core 2 quad core, and up to 8 GB, with a very good SATA2
controler (that has "hardware" raid option in the BIOS that I never
use). I'm very happy with them, especially when using the AOC-SIM1U+
IPMI board (integrated KVM + virtual media over LAN).
