This won't help if one has an earlier cube. Can we open the rear panel and simply reverse the fan, if our cube is the older one? Has anybody done this? I think somebody asked this once before, but I havn't seen the answer. To make sure, if the air comes out from the rear panel, your cube is an older one, and your optical may get a lot of dirt.

Has anybody done this? After my second optical drive died, I had several conversations about this with NeXT people both here and in California. They are aware of air flow and several other problems with the robustness of the optical drives. They told me not to reverse my fan now, as that would probably precipitate some other problems, but that shortly they would have a uniform retrofit to all existing cubes which would correct all known OD problems. Like the replacement of the early optical drives, this will be free. At present, they said to be sure to keep the cube off the floor, and to keep the surroundings clean. From my own experience, I would recommend vacuuming the air slots on the back and bottom from time to time, rather than blowing off the dust, which can be amazingly deep.
