You're doing almost exactly what I'm doing right now. In fact I just
finished the main build tonight.
My config is:
Supermicro PDSMA mainboard
Q6700 quad core intel
2x seagate 500Gb drives in Raid 1 for OS and basic backed up storage/NAS
Supermicro PCI-X SATA card
4x WD green drives 1TB ea in JBOD.
the mb has 2 Gb nics.
I think your choice of hardware is fine. I also plan small diskless
frontends booted off images on the server.
suggest you get a separate drive for your OS and mysql database. Use
the rest in raid for your storage.
