I currently have a netbooted frontend but the boot image is on SSD so that is very fast and I suspect a second (or more) netbooted system would be little extra load.

FWIW my _master_ backend/frontend combo is an Atom and it works fine. 
Uptime says:

20:34:00 up 31 days,  7:00,  8 users,  load average: 0.12, 0.08, 0.03

I have another Atom server which also works fine.  IMO Atoms make better 
servers than workstations, but of course you need the right expectations!
