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.

CPU load should be very light indeed. I run my master backend off a
Sempron LE1250 and the load on the CPU is low. The issue that I
sometimes run into with multiple recordings (=>4 concurrent) is that
the disk IO is insufficient. I record to a single drive and until last
weekend only had 1GB RAM. Now I have 4GB RAM installed so hopefully
bigger disk caches help out somewhat. So CPU I would not worry about,
but 5-6 recordings would put a strain on disk IO and perhaps on
network IO also.
