PC mods Has their bay bus on sale for $19.99. 6watts per switch, which should handle one to two fans per switch unless you have screamers that use more then 6watts. Three positions, on, off, and veriable that you set. And you just have to drill your 5" drive bay cover plate. To me its a resonable price, and no I don't have one, but have been meaning to get one for awhile now, just other projects that I want to do come up.
