For me the designs 1 and 2 can be better if the psu is in the front ( on the right of the motherboard) with a extension cable to the back. it intakes air from the front and exoust to the top or side like the node 304 or dan, etc. what do we win with this? - the hight of the cpu cooler can be much taller and we dont have th to use watercooling to cool properly the cpu. the famous sg13 has this problem and some people mod it so they can have a better air solution (like the noctua L12) because they dont want water and pumps doing noise in their systems. watercooling can still be an option. if you make the prototype 1 with the psu on the front and make it with the depth of the sg13 or a little smaller it can be a winner. or maybe i'm wrong EDIT- I took the time to read some posts and this was already suggested...
