Which is the best from cooling aspects?
I will probably go with water cooling my cpu.
Please don't come here with other cases it's just about these three.
The case won't be moved so I don't really care about the Storm Stryker's handle on top of it.
I Have HAF 932 advanced very happy with it apart from having to cutout the motherboard tray opening for my CPU cooler back plate. Something I would have not had to do with the HAF X that gets my vote.
I would say HAF X, or the black version of Storm Stryker which is Storm Trooper.
I don't like the trooper because 1. you need to buy a window for it separately
2. it looks better in white
But basically they are the same except the color, so the functions are the same.
