Well, I went ahead and cut a hole in the permanent case side panel for the cpu tunnel ram tube (I had been using a card board temporary panel). I decided that mod was so effective in cooling the cpu that I'd keep it. Yesterday, I cout two holes in the top of the case for 80mm fans. They are placed in an empty space between the PS and the floppy. Knocked about 3 degrees Celcius from the case temp. My next cooling mod will be to replace the 80mm fan in the front of the case with a 120mm fan. Right now I have three 80mm fans (2 on top, 1 in back) exhausting and only one 80mm fan pushining so I'm guessing if I give more push in the front I will get a stronger through put.
