Hello All,
Here is a pic of the final build of my open air PC build. I built the case about 5 years ago and have been running a 10900k.
I have stepped up to a 9950X3d and the Asus Crosshair ROG 2006 X870E motherboard.
I have 3 x 360mm radiators and a pair of D5 pumps in series.
Let me know if you have any questions! J
Not OP, but own a similarly open-air PC (Thermaltake Core P3).
I bought a Wolfbox MF200 duster on sale off their AliExpress store for ~$50USD; just need to just give it a quick blast every once in a while and it all remains dust free.
Honestly dust management in open frames is significantly less hassle than in closed cases - regardless of positive/negative internal pressure.
