[CentOS] RAM for cluster net boot?

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.
