SetsulThe problem is if you can just pick any case of about the same size that limitation doesn't exist. You don't have to do insane things like cramming an NH-D14 in a 13l case but you're not limited to aios.
I love the Rajintek Metis, a friend has a build in one. He did have to drill all the GPU ventilation holes and because he migrated from a Node 202 (with longer GPU clearance) he had to take out the front USB/audio to get a 266mm 1070Ti in. Having to reverse the PSU fan to get it fresh air is also annoying.
Personally, I think the NCase M1 is a great example of a compact case supporting good air coolers and overclocking.
SetsulI mean you saw that the ML08 would fit neither a large air cooler nor an aio so you went with one that only fit aios, but not large air coolers.
That's an unnecessary negative way to look at my motivation, I simply went with the SG13 because that's the one I've built three PCs in (and two in its SG05 predecessor), because it's a great case for travelling with, supports decently long GPUs, because you can overclock it if you pick the right parts and you can run it as a low noise build.
Since I have experience with most of the parts and type of build the poster mentioned wanting, I thought I'd share those, but I'll get off your lawn now.
