There's a good ~20mm between the GPU and the window, so much like the original design, it shouldn't have problems with intake restriction. Granted, with the 140mm fan over the CPU being the only intake, the GPU does get somewhat warmer air than it would with vents directly next to it. That's the trade off, though. Naturally, the 140mm intake is intended to be filtered.The design looks nice, although I'm not a windowed case person. I'd rather prefer a perforated panel for the GPU to breathe, personally.
That's what I'd aim for. As of right now it looks like with the Zotac GTX 1080 Ti mini's tall PCB (125mm), only 80x15mm fans would fit at the top with the current height. Short cards closer to reference height would allow for full thickness exhaust fans there (though this depends on the PCIe power connector location on the card, too).Would the top 80mm fans be able to be mounted without the screws being visible on the outside ?
Ideally, that's what I'd like to do. @CircleTect's idea of using a single machined piece for the back is quite good I think, and I might try something like that. Cost could be an issue doing it that way though, so not something I can say for certain is a possibility.The rear I/O and GPU seems to be indented, is that going to stay if the project proceeds ?
40mm excluding the 25mm thick intake fan. So 65mm total is what's available. The Kozuti might be a good choice for this case, with push-pull being possible using its own 80mm fan plus the 140mm intake.Is the CPU heatsink size limited to 40mm with a 140mm x 25mm fan attached ? So something like the Scythe Kozuti with exactly 40mm height (without extra fan) or a Noctua NH-L12 (with bottom fan) would be ideal.
One concern I do have is the size mismatch between a large intake fan and small heatsink. As we've seen, this setup often doesn't perform as well as a smaller fan that better matches the intake area of the heatsink.
It really depends how it's executed. I'm fussy about where the bends show, and hiding screws and dust filters and such, so it may end up being more complex than it looks.It also looks like a relatively easy to fabricate design, did you focus on this aspect specifically or is that a coincidence ?
