Medium tower but massive
Ordering this tower on delivery was the worst idea ever. 12kg to carry for 30 minutes definitely hurts your arms!
On the other hand, I'm still very happy with the quality of the Be Quiet! cases, even though I already had their large tower model. Easy to open, easy to assemble, maybe just a little problem with the fan mounting grid at the top of the case, which can get in the way of the RAM bars depending on the size of the fans.
But there's nothing insurmountable about it, and it's still as quiet as ever. On the other hand, on the two towers I've had, I've no idea how the speed selection pin on the case fans is connected... It's connected to the controller pin on the motherboard, but it's not essential.
