Japanese casemod is very nice, indeed. But i saw yellow color wires, and asked myself: why some yellow there? And why is radiator block in silver color? If you look at color style, it's mainly red/black but not so many silver/gray. I think the radiator should be in black color, to make it better looking. Now the silver radiator is big color there and it looks bit strange. I cannot see the meaning in silver radiator.
So I think the Japanese has small flaw in color style.
I will vote to Netherlands, because the design has less flaws and it looks very great, its great show-off with lights. Nice for game nerds.
Only i am surprised the Germany with pirate casemod is less liked, because it has many great handwork. Might because Tt parts are less visible? (Same for Star Trek version, is too much customized so the original case parts are already gone.)
