Take a hardware raid controller with battery backup write cache (512 - 1024
MB).

RAID1 is ok (mirroring)
RAID10 is (maybe) better

Normally I would use SAS Disks (instead of SATA2). How about RAI10 with SAS
?

It is ok. Is your OS linux ? RAM should be easily expandable to 8 or 12 GB.
Do you use an 64 Bit OS ?

Both are ok. The AMD is maybe cheaper, but hard disks, RAID controller, RAM
and a good database design/import scripts are more important.

Do you have an server for testing ?
