Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	369mm case limit	304mm GPU	PASS · 65mm	Manufacturer verified
Height + power cable	190mm case envelope	173mm (137+36)	PASS · 17mm	FitMyPC estimate
GPU thickness	85mm case envelope	61mm GPU	PASS · 24mm	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.
