How much real cooling can you get with the cheap peltiers you find for
sale on Ebay. My shop gets pretty hot in the summer, but its just not
practical to keep my controller computers in the office. I was
thinking about making mini duct/shrouds to draw air over the cold side
of a peltier into the PC cases.

I've used them quite a bit, cooling optics, built a small
environmental chamber etc. Without qualifying it with numbers I'd say
you would be wasting your time trying to use peltiers to cool air for
your pcs. Would using a very small thru wall compressor aircon unit be
possible? They are quite inexpensive.

My shop is 3000 square feet. About the only thing I can think of might
be to use an equipment cabinet and a small AC unit on it. Seems pretty
inefficient.

Inefficient how? If you can arrange all the confusers in there, it may
be just what you need. At least until the AC dies and you don't notice...

To beat the 'airflow' drum again -- how about an equipment cabinet and
just pipe in outside air?
