If going ATX then strongly recommend the Fractal R6. Comes normal with no glass side. (same, i dont get the purpose of glass panels as i REALLY dont get the idea of putting your PC on the desk. What a waste of real estate. Put it under desk).I'm likely getting a Meshify C for the case replacement (full size version).
The case is one of the quietest ones on market and probably one of the most configurable with everything - radiators or air.
Also Fractal has superb build quality and great support - like noctua. No threaded screws or having to push in backplane to fit cards. Also theyll answer your emails in 24 hrs or less.

Lo & behold it was the featured build of the week with not a single LED / RGB nonsense. (I dont even plug the power LED in). Its been upgraded soemewhat since 2018 - 2080ti, replaced the 3tb black HDD with a 12tb Ultrastar and upped the 1tb 970 with a 2tb model. (I had bought a 4tb qvo to replace the 3tb HDD but sold it before installing.)
Note that evey hole / filter is taped up (even pci cover grilles with clear tape). Air in via front filter, air out via PSU, GPU vent and rear fan. Front to back.
A ton of static pressure and totally silent.
If i could change one thing it would be a screwed in rear fan grille instead of having to use the dremel. But that option is very rare (only seen it on an old Lian Li case i had). Also its being very picky.
And front 4x usb3 instead of 2x usb 2 & 2x usb3. Its a simple mod though. (They now also come with usb C)
