Advice on Cluster Hardware.

Ooh, didn't realize this was out yet! This is a preferable board
compared to the Asus A7M266-D because it trades a useless C-Media
sound chip for an integrated 3COM 10/100.

The main quirk I noticed when playing w/the Asus board: NO USB (not
even 1.x) support. If, for some reason, you need it you are forced to
use a USB2.0 PCI card. The Tyan boards have good old-fashioned USB1.x
support on-board. This means you basically can't use USB console
switches with the Asus.
