As of sitting in front of this computer screen, i notice that my trusty (and mostly dusty G4) is some what loud compared to my G5. I know this is so because there are more fans on the G5 and it obtains better cooling that way,but i want to change that. My recent mod, the power lego mac, wasn't based on anything but combining legos and computers. This time I want to do something neat and need ideas to help, but the thing is I don't want to build something in a PC case (don't want it to look like I'm going to the dark side), I want to build it from the bottom up. Any ideas please.
