Not sure if this is something anyone has looked into, but I'm curious to learn what's the absolute minimum width of a case with each of the following:
125mm CPU cooler height restriction (Noctua U9S, Cryorig M9)
140mm fans at the front
bottom ATX PSU compatibility (is 150mm + thickness of side...
No CPU intake or PSU exhaust?
I might be an outlier but I'd rather see a simple unobstructed front-to-back airflow, PSU at the bottom (or top if inverted mobo), 4/5-slot but ATX-mobo-compatible layout, even if that adds a bit in height (and hence volume).
I think I get what you mean. The flanges are still there, just not shown in the drawing since it only depicts the cross-section. The side panel isn't just the top and bottom, it still has the sides.
I guess the challenge would be how to make the window/grooves detachable.
Another problem I have with typical windows on cases: dust. It looks awful when lit.
As for mounting, maybe there are inspirations we can take from real world architectures, something like minimal metal framing, some sort of gasket, no rounded corners.
I'm usually against windows, but in this case I'm OK with it as long as it looks as least as good as tempered glass, instead of a cheap piece of injection molded plastic, like most non-TG windows in commercially-available cases.
I have to wonder though, how much a piece of PC/laminated...
Where does the PSU go? I see 350mm height and ATX mobo support, so that rules out the traditional bottom rear placement. Top rear is possible at the expense of a couple expansion slots but that might conflict with top 240 radiator placement.
