Is this case wide enough to support a cooler master hyper 212 evo?

I know what the official CM specs are, but I think it will fit. This guy installed a taller cooler with its cover and it fit. https://www.vortez.net/articles_pages/cooler_master_masterbox_q300l_review,8.html

I've seen photos of the handle (from a Q300P) being attached to the center of the top panel of this case. Is this possible?

You can remove the plastic bit that has the cooler master logo on it and install handles on the case like the Q300P

what are the size and placements of the fans?

There are 3 fans (120mm) in total. 1 exhaust fan in the rear, and 2 intake fans at the front. -CM Myke

Does the case come pre-assembled?

Hello Kevin, The case does come assembled, but you will need to plug in the connectors, and open it up to install your components. CM-PNguyen
