You're right a hard drive solution would be quicker. I'd personally rather not have a disk in the machines to cut down on heat and noise (updates too). For most people I would agree that a disk based setup is the optimal way to go or even booting with a BartPE CD / DVD is reasonable way to go.

I can run swapless on 2G of RAM (with no noticeable performance problems and plenty of free RAM on a non-PXE boot) so I was planning on using 3G to 4G of ram on my PXE clients to help give them more breathing room.
