Room where PCs are is very warm...

[Jeff7]

Any electrical device is going to generate heat when it's powered, so it's dumping energy into its environment - your living space.

So you've really only got a few options:
- Reduce the power usage of the devices, and therefore the amount of thermal energy being dumped into your house. (Undervolt/underclock, get more efficient components.)
- Ventilation to move the heated air throughout the building and keep the temperature equalized.
- Remove the excess thermal energy from the room, and dump it outside the building. (Air conditioning.)

I work from home...

I have my laptop on one desk, my tower and monitor (see signature) on another in an "L" set up.

Do you need a second rig? Just leaving it off can help tremendously.

Alternately, if you want to get serious about reducing heat, then have a separate work system as your secondary. Use the lowest end Sandy Bridge CPU you can stomach and don't overclock. Use integrated graphics. Use an LED backlit normal monitor. Done.

Overhead ceiling fans only help humans evaporate sweat, thus making us feel cooler. It won't make the room cooler, although it will help

Actually if you use a ceiling fan and box fan in a "push pull" config the actual room temps drop. It's just like positive pressure in a computer case. Cool air in, warm out out = temp drops.
