Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	410mm case limit	304mm GPU	PASS · 106mm	Manufacturer verified
Height + power cable	190mm case envelope	173mm (137+36)	PASS · 17mm	FitMyPC.net estimate
Installation envelope	85mm case envelope	61mm NVIDIA case-clearance envelope	PASS · 24mm	FitMyPC.net 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.
