Reygie,

Tore is ABSOLUTELY right.
If your client does not want to buy many UPS's, I recommend you to show him how this problem can be solved.

Here, in a first moment, I bought some few UPS's, and connected 4 CPU's on each. Just the CPU. I left monitors, printers, audio outputs connected to the normal energy, outside the UPS.

Believe me, after that, all my problems had gone.
Today, each machine has it's own UPS. We think that more important than having a good performance machine is to have a UPS !

HTH
