Just wondering how you made out with this board. I've *just* picked
one up myself, and am wondering whether the onboard P4M800 worked for
you with this config ? Have the setup stuffed in an Antec Aria case.
Not the slimmest in the world, but the built-in cardreader might even
allow for a completely HD-less setup if I can store my setup config
for Knoppmyth on a CF/SD card.
Any gotchas one should look out for ?
Thanks in advance,
