Just ordered some new pieces parts, decided to build a rad box. It "should" be fairly quiet using a "few" of the fans Zogthetroll came up with an a couple of real odd single pass heater cores I found. All going to fit in a Chenbro 19 in 4U rackmount case, with empasis on keeping external air velocities low. Will post pics when it gets put together, which may be a month or so
