Well if you like I can give you some real world measurements when I'm hope later, although I really think it must fit, this case is made to fit everything and anything.
I'm not sure, unless your motherboard tray sits really clear off the back of the case or something? Unless the measurements are just plain wrong..
Thanks for the offer but I would not put yourself out, from what I have found it will fit. The only thing I can think is my case is an older version of the current antec p183 so maybe they made it wider in the new model.
I think I have my head around the size now, case wise I am between the Elysium, Aerocool X-Predator and the Phantom (assuming it measures with enough space).
Just to add thanks to everyone who helped out, it really has helped a lot.
