I'm going to be modding my case hopefully today, to add a fan in the side window (Possibly to pull air out, though I'll test what gives the best results).
Its only thin plastic I believe, so might be able to do it with house hold tools (I have no specialist equipment).
This is what it looks like so far without any adjustment:
(I have updated the CPU heatsink/fan since the image to a Arctic Cooling Freezer 64 pro, pointing to drag air in from the back two fans now in place)
I'm also wondering where about to fit the hole for the new fan. Above the new heatsink? To the right of it? Or towards the bottom of the case where the video card, etc is?
Any help would be appreciated
