Why bother hearing what they might be? He's made it clear has no idea what he's talking about. That's why Jeff and I are talking about manufacturer-specified air cooler clearance heights. Your 5000X is specified to support air coolers up to 170mm. This is better than knowing the width of the case because Corsair is telling you the distance between the face of the motherboard once installed and the side of the case.
There's a reason PCPP has a filter for CPU cooler clearance and not GPU clearance. Because outside of SFF builds the GPU height is less commonly an issue. If one buys a liquid CPU cooler, then the GPU will still be the tallest component on the motherboard. But if you buy a robust air cooler, the air cooler is the hog. That's why PCPP knows builders will broadly be more concerned with knowing air cooler clearance than GPU clearance.
The GPU you've selected has these dimensions:
(L) 359mm x
(H) 149mm x (W) 70mm
The air cooler has these dimensions:

(L) 110 mm x
(H) 154 mm x (W) 125mm
And, so you understand, the GPU height factors in the bracket. The air cooler can't get lower than the seat of the motherboard on top of the CPU.

You don't need a case the size of a freaking office file cabinet for a computer. It's absurd.
