I'm kind of partial to my LL cases. They're solidly built and using Yate Loons especially the 120mm for additional cooling has kept my temps down.
I like the intake fans cooling my hdds and having fans in back and top for exhaust really helps, I think. Adding a separate side intake works for me too.
The LL PC-7B +2 version is great because of the 120mm intake and exhaust. Replacing the top with a 120mm, plus adding 1 to the side makes a fantastic cool machine.
The results and overall costs are really surprising. I have all kinds of info if you're interested. My recent builds are really benefitting from the addons.
Hope your case is as cool as mine.
