When I got it second-hand from my uncle, it was noisy, collected a lot of dust, and didn't exactly run cool. Over the past few weeks I replaced the CPU and GPU heatsinks and all the fans except in the power supply. The filter is a furnace filter I got for $7 from Home Depot. Now it runs quiet as a whisper, the CPU/mobo run 15C/5C cooler under full load, and only time will tell if it accumulates any dust whatsoever. My guess is no :V
(Decoration in this last pic was not mine btw)
To show some of the inner construction, here it is without the filter on:
May dust never enter your computer as long as ye both shall live.
). This is to prevent dust entering my computer through cracks and holes in the case, as air will always be flowing out, not in. To accomplish this, I have 3 intake fans (2 120mm, and 1 80mm; two of the fans are hidden in the pictures; there is one on the front and one on the bottom of the case) and I have 1 exhaust fan (the one in my power supply) and 2 open vents. I tested all vents and holes on my case for sufficient outward airflow using a small square of paper attached to a thread. Higher air pressure inside the case may have some small cooling bonus as well since higher density theoretically means higher thermal transfer. Just an idea, but it's doubtful that it's of much significance in this case.
