Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	415mm case limit	327mm GPU	PASS · 88mm	Manufacturer verified
Height + power cable	165mm case envelope	156mm (128+28)	PASS · 9mm	FitMyPC estimate
GPU thickness	70mm case envelope	49mm GPU	PASS · 21mm	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.
