Try any one or more of the following:

1. Move the RAM card to the bottom slot.
2. Mount a second fan over the slot openings at the rear of the case.
3. Mount at least one of those drives *externally* rather than internally.
4. Get one of those fancy efficient power supplies with two fans to replace
    the one that is there now.

5. Go to Radio Shack and get a heatsink for the FPU.  Attach it with silicone
grease to improve the heat transfer efficiency.
