What OS are you using for your diskless client?
I've been trying to set up a pundit diskless frontend using Fedora, but have
had 0 luck. I've managed to get it to pull a boot image from my dhcp/tftp
server, but I keep on getting init errors when it starts loading...
Anyone know of any proper diskless client instructions?

Sounds like a good video card.
To answer your question. I am using the diskless system as a frontend
and backend slave (one pvr350 card). It does fine as this, but I try
and avoid any heavy work like commercial flagging on this box as it
gets loud when all the fans start spinning up. All the heavy work is
done on the nfs master backend box.
Guess that leaves the chip, memory (I have 512Mb), or nfs optimization?
