Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	440mm case limit	242mm GPU	PASS · 198mm	Manufacturer verified
Height + power cable	200mm case envelope	148mm (112+36)	PASS · 52mm	FitMyPC estimate
GPU thickness	90mm case envelope	50mm GPU	PASS · 40mm	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.
