Hi,
The mobo companies seem to be slow to get integrated LAN/SCSI/etc onto SocketA boards. I've currently got an Asus P2B-LS, and am waiting for a similar mobo to you.
Closest I've found is an msi (http://www.msi.com.tw) with integrated video, firewire and Ultra160 SCSI (AMD760 chipset) - no LAN tho :O(
As for servers in racks - i think the only workaround would be to use USB or Firewire and connect LAN etc that way - less than ideal though. There seems to be plenty of choice with Intel mobos with integrated stuff...let's hope SocketA catches up soon.
