Standard 80mm Akasa Amber fans mount in there with no problems.
It looks like there isn't enough room for standard thickness fans 'thats what I thought originally' but they go in with loads of room at the back.
Just hit a major snag as well, spray can fell off shelf onto the plastic front panel and cracked it at the top.

Managed to glue it together and sand it flat again, another spray of primer before the black, so thats set me back a fair bit as I can't now start the black until a lot later.
