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.
