Thank you for feedback!
Disorganized grew on me too, was one of the earliest patterns I drew and I kept going back to it over any variation of hex, rounds, obrounds etc. Rectangular just matched the overall shape of case best. Standard repeat pattern was too generic or too close to other designs I see on this forum.
I also drew up irregular on both ends? I like this best.
Cutouts will not affect rigidity, those cutouts are more to hide the fact that panels will not be perfectly inline. (see issues with Cerberus panel gaps.)
This case will be unbelievably strong based on the frame design - I could probably stand on it.
Dust yes, get an air compressor. =P
No plans to change the front for vents now as there's too much ugly cable/rivet/PCB/etc. back there. Plus the standoffs I use to have no screws on front is exactly 25.4mm long, and that's the longest one they make. With the material being 2mm thick I only have ~23mm of space, and there's no slim RGB fans that would look cool in that limited space.
I was going to add more ports to the side front slots, USB type C, audio, etc. Maybe change power button.
Think I'll run the prototype per above because I'm 95% happy with it and get some more feedback.
Needs a name, thinking something to do with the side panel shaped like a K. And I do need some volunteers to test prototypes though! (I don't have any graphics cards to fit check the 2.5 slot width, not worth buying a $1200 GPU to go "yep, fits")
