Yeah I don't think there is anywhere to put the radiator. Unless I also watercooled the CPU and shared the rad. The case isn't that tiny (NZXT h100). You might be able to get a rad in at the front even with the CPU air-cooler in place, I dunno.

I checked if there was a 2-slot water-cooled 5080 and there isn't - dunno if other cards offer anything, I'm just using that as a litmus test. I'm guessing most people in the market have a big tower, and maybe that's what I'll end up doing. The reason I got a small case originally was to take it on the train to LANs and now I have a car so it's not a problem. BUT I do put it on my desk instead of under it, and a full-size tower wouldn't fit.

Doesn't watercooling only add more parts, unless you're putting the radiator outside the case?
