not exactly. what are you planning on doing with these machines? Once they boot (which is maybe a 5 meg or so file) then the file system is pulled from an NFS share. You can do the entire OS and file system in RAM, but why? A server with 512meg of RAM will be MORE then enough to serve as a PXE server (to boot off the network) and an NFS server (for the filesystems). Smack in a 100 gig harddrive and you're golden.

I'm looking at building a small cluster of disk-less 1 or 2U servers and will probably use CentOS 5.
Since these machines will not have any hard drives, what would be the minimum amount of RAM I'd need? Also, if using Rocks or something similar, will that help cluster the RAM together so 4 servers x 4 GB RAM each = 16 GB available?
Some applications might be CPU intensive, others might be RAM intensive, so I need to play that balance, too.
Thanks.
