NeXT cubes were designed with the fan exhausting air, so the crapola sucked in through the optical drive slot wiped out the optical drive before long. NeXT eventually approved the procedure to mechanically turn the fan around (do *NOT* simply reverse the connector). Problem is the designers actually did do _some_ thinking. On its way out the fan in the original configuration, the air went over the logic board(s) first, then the power supply and drives last. Reverse the fan, it's now hot air hitting the logic board. On my system, this caused the SCSI controller to fail occasionally. Solution in my case was to put the fan back to its original configuration, then tape over the floppy and optical cut-outs on the front of the case. (N.B. my system may be unique in that the floppy is mounted with a custom mount to an optical-sized cutout, with no attempt to seal well. It may be that either taping or reversing the fan would have solved the problem.) -- - Mark 210-522-6025, temporary cell 240-375-2995
