I think with v2 this might be possible if it's wider. With my water block and GPU, I measure 49ish mm from side panel to gpu, so slim rad plus fans (45 mm) have very little breathing room. I think most with dual rad builds put the slim rad in the bottom right now (myself included). Plus the side mount rad would hide the sexy waterblock@KSliger I got to thinking about all the empty space in the GPU side on my build (sm580), and how well the gpu fan intake + top&bottom exhaust works for thermals. For v2 what about throwing in 4 rivnuts top and bottom/ front back and have an optional support bracket for a 240mm slim rad vertically like the nCase M1 has. Correct me if I am wrong, but there is about 80+ mm from back of gpu card to outside panel. That, I think is enough room for a slim 240mm rad + fans + waterblock + gpu card + 10-20mm air routing clearance. It would be tight, but a slim 240mm + 280mm rad up top + 6 fans would be alot of cooling tdp. I've got a rivnut tool on order, so I plan tinker myself. I'm also thinking of adding a similar bracket to mount a slim fan directly over vrms to better support the 3950x when it comes out.
