Ow, GPU constraints from the main site, DAN Cases :
Dual-Slot up to 300 mm length
Length
Complete card incl. bracket: 306 mm
Without bracket: 295 mm
So the INNO3D40805080 300mm should about fit with no modifications required. However the 5090 founders is 304mm.
Believe generally card dimensions 'length' from vendors is without the bracket.
edit: yeah, i meant 5080
I was eyeing the 5080FE as a viable upgrade but haven't found user verified dimensions online for it. It's shown as 304mm too
Don't want to let go of the A4 but the 1080ti needs an upgrade and INNO3D is hard to get States side
