multiple PC boxes, setup, cooling, logistics

[RSM72]

There are some logistical problems that come with having 5 PCs.

- Noise
- Heat
- Lots of cables

If those are your main concerns with the solution then seriously you should consider going with a single box and probably a second (passive) incase you need the performance for 10 clients.

Since you seem to have reasons for running a single client per machine could you please give us those reasons?

b) Is there a combination of ultra-quiet and ultra-cool hardware that I should know about?

The usual solution to that problem is watercooling with using an oversized radiator and multiple large (slow running) fans.
