Hmm.. I can upload the picture, but am not quite "there" yet. I can only figure out how to include it in a post, if I am creating a new post. I can't quite figure out how to include it in a response.
Anyway, here is my hillybilly cooling system. I have a System Saver fan running, but was still not happy with how warm the interior of the case was getting once I installed the accelerator card. Perhaps the 25+ year old system saver isn't running as fast as it once did.
The system saver fan is quiet, but it is still noisier than the little USB fan I have pointing into the rear of the cabinet (which I can't hear at all).
Note how I have the front of the cover pointed to the rear for better access to the fan. The rear sits quite securely where the front used to be.
