Question about Cooler Master Cosmos C700P

So in terms of length, the top is 360mm and the front 420mm. Coolermaster specifies a maximum thickness of 80mm at the top including the fan, which I find very tight with the CPU power plugs, but you never actually have to take them out... The icebreaker is already very thick, could be tight with the fans, but you don't need shrouds for that. I'm also installing two 360 45mm radiators. You would have more space at the front, where you can certainly fit 60 or even an 80mm thick radiator, depending on where you mount the AGB etc. I am very enthusiastic about this case and can only recommend it.

You won't be able to get it in at the top, or the fans would hang directly on the mainboard (the icebreaker is about 5.6 cm thick).
It will work in the front if you remove the mounting frame for the optical drive. I have a Nexxxos 280 on top (4.5 cm thick) and a Nexxxos 360 in front (also 4.5 cm thick).
