They are behind the mobo tray haha. My psu is longer than most so it covers up the hole there in the mobo tray some. The only way I could get the cables behind the mobo tray was to bend them like that. Dremel could fix it though.
I assume you are talking about a tray that can be removed? My case does not have that. Any tips on how to make it better? I have thought about getting a different case.
