So what did I like about this case? Well, pretty much everything. The fit and finish confirm what I have seen with other be quiet! products, which is that no corners are cut to save money. The chassis is robust and the workmanship of the assembly is top-notch. As far as functionality goes, there is a ton of room in the case and by room, I mean the ability to handle multiple fans, liquid cooling, multiple hard drives, and large motherboards. Just about any configuration of fans and radiators you can think of are covered in the Dark Base Pro 900. You can get not one, but two 420mm radiators in there - one at the top and one in front.
