It will be a pain, but I would mount the board, then connect the cables, then shift the PSU into place.If I'm looking at this properly, it'll be very difficult to work on a motherboard in this case. The PSU is literally smack-dab in front of the motherboard, how are you supposed to connect stuff with the PSU in the way?
Yeah I was thinking the same thing, but with a seasonic fanless power supply. I wonder if that would have issues though, I don't own one but reading up on them, it looks like the fanless PSU needs to be facing up toward the top of the case to not release heat all over the rest of the components. If it all worked, it would make for a pretty sweet silent build.I wonder if you could get away with PSU and GPU that are able to shut off fans for low power, and a large passive cooler. That way, you'd have completely silent operation until you stressed it - like for gaming at which point you'd throw on your headset.
