Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	360mm case limit	287mm GPU	PASS · 73mm	Manufacturer verified
Height + power cable	190mm case envelope	151mm (123+28)	PASS · 39mm	FitMyPC estimate
GPU thickness	85mm case envelope	63mm GPU	PASS · 22mm	FitMyPC estimate

Some case clearance fields used by this result are estimates, so treat a pass as a likely fit rather than a manufacturer guarantee. A front radiator can reduce available GPU length and change this answer.
