Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	360mm case limit	342mm GPU	PASS · 18mm	Manufacturer verified
Height + power cable	190mm case envelope	188mm (152+36)	PASS · 2mm	FitMyPC estimate
GPU thickness	85mm case envelope	70mm GPU	PASS · 15mm	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.
