Built this especially for my new case. (copy pasted from my regular forums) This is a dust filter box that the case will sit on top of and draw (hopefully) dust-free air in. PICS TIME! What it will look like. Some stuff cut. Screwed some things together. And some more things. Then these little things also. He went up here like this. Then another. They hold up a sliding piece which kind of closes the gap once the case it all closed up to stop airflow coming through the top of the enclosure. Some edging to help seal the gaps. More edging. Woops. Bent a bit. More images to come once I can make another post. No more pics of the building process. PC pics and finished product next. All gaps were filled in with hot glue BTW. Ready to build. Bye boxy. Got a bit dusty there around the end. Everything in except the power cables. Just something to make things easier in the future. A look underneath. Cover is off the box. There is an identical sheet of wood on top with 2 holes to secure the filters. Cover on and the air is sucking through. I used Aldi equivilent of Chux wipes. It's ok, it's all sealed - There are 2 of them so that bit hanging down reaches over and seals the hole on the right. PC. Zoomed out. Current setup. Will probably add some LEDs at a later date. Thanks for watching. Look after yourselves.
