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.
NGL, I am tempted by some of those - but as a CachyOS user - would that just make me a poser?
Like, the equivalent of stolen valour? 😅
