Thermaltake’s Versa H17 MicroATX PC mini tower case is an excellent minimalist case with a relatively small footprint. I chose this case, because it doesn’t have a side window or excessive RGB lighting. I wish that I could disable the power light, which is a bright, room illuminating blue, but I simply cover it with a microfiber cloth.
It’s designed to have air instake from the edges of the front face, which are covered with a fine grill, a 120mm opening at the rear bottom of the case with a magnetic dust filter for the PSU, and a larger approximately 3/4″ x 4″ opening at the bottom of the front plastic face assembly. The latter is a problem, because it’s basically a rectangular hole through which dust enters the entire case but especially in the shrouded PSU/disk zone in the bottom of the case.
While working recently on my desktop computer–swapping out video cards and installing a new SSD–I figured that I should do something about that air inlet. I used what I had on hand to create a DIY solution.
First, I took this airline supplied sleep mask. I could feel that it had foam underneath its outer fabric layer, which would work great for capturing dust before it enters the case. I used scissors to cut into the face of the mask within the sewn border.
After cutting into the mask, I found two different kinds of material. On the left is a soft 1/16″ thick white foam and on the right is a thin cotton-like material that might also be used for face masks and personal protection equipment (PPE). For my project, I opted to use the thicker foam on the left. While it might not filter as much dust as the fabric on the right, I think it will give a better balance between airflow and filtration.
I pulled off the face of the Thermaltake Versa H17 case and taped the foam over the air inlet with a piece of packing tape.
After reattaching the face, the foam covers the air inlet. It might take a few tries to make sure the foam covers it completely. The use of additional tape on either end of the foam might help.
