u can put the side panel back on/off while the hdds are connected.. well i can
nothing has snapped off mine, though the top panel usb ports arnt that smooth when u put ur usb in but it still works fine.
i have a cpu 212+ in it (although it fits closeish to the ram, but still good, but you wont get another 120mm fan on the top part of the window panel, but u will fit one on the bottom window bit. and a gtx560 ti OC in in. one cd drive, lcd fan controller, usb3 hub and i even fit another fan under the cd drive.)
the only issue is that i brought a nzxt lcd fan controller 2 and the led switch doesnt work when the fans are plugged straight into the controller.
but otherwise its pretty cool.
feel free to ask me anything about it or if u need pics
