ok, i just wrote this nice reply, and it turns out that my file was too big, so i'll try again. there's a pic attached that's kinda what i'd make the hs like. the raised square fo the pelt would be the same height as the fins. the baseplate would be pretty thin, the only thick part where the peltier would sit. the drawing is a "top view".
yeah, the intent isn't to freeze the hdd, just keep it around ambient or so
how much would you want for that pelt?
thanks for the info all
i'll start working with the hs a little, see what i can come up with. i kinda hate carving out a copper block, but i'll ponder it some more and see what i can come up with. i'm usually pretty good at that
