be quiet! Dark Base Pro 900 Rev 2 Full-Tower Chassis Review

A Closer Look – Interior

The interior of the 900 Pro Rev.2 is absolutely vast. There is room for up to an E-ATX, or XL-ATX motherboard here, meaning pretty much any enthusiast motherboard should fit with ease. This includes the larger X299 and TR4 motherboards, as well as Xeon based dual-socket motherboards. When you first open the chassis, there are a few accessory boxes, and we’ll take a look at those shortly.

With the boxes removed, you can see there’s plenty of cable routing room here. There’s a large cut-out behind the motherboard, as well as rubber grommets, and pop out plastic cable shrouds towards the front. It that wasn’t enough, there’s also a full-length PSU shroud too!

PSU Shroud

The shroud comes with modular covers too. These covers can be taken off completely or in sections, freeing up space for cables and other hardware to pass-through as you see fit.

Up front, there’s plenty of room for your cooling hardware. If you’re planning to go custom loop, you’ll not be left short of options. You can fit up to a 420mm radiator in the front. However, if that’s not enough, you’ll get another 420mm in the top, 140 in the rear, and can even mount cooling onto the PSU shroud.

The chassis is very wide and very long. Of course, that means that even the biggest GPUs on the market should fit with ease, with room to spare for water cooling pipes and pumps, and then still quite a bit of room left over still! All of the expansion slots come fitted with reusable covers and thumb screws.

Up front, you’ll find two 5.25″ drive bays. It is removable if you want the space for cooling hardware though. However, for workstation builds, optical drives can be very handy.

There’s a multitude of installation options in the top too. Don’t worry if you’re not using them, as it’s still very well soundproofed here too.

Noise Dampening

Removing the right side panel, you’ll find another dense layer of sound dampening material. The panel is pretty heavy too, not that a chassis of this size was ever going to be lightweight, of course.

Even the back of the chassis looks very neat and tidy. There are a few cables running around at the moment, but these are just from the pre-installed fans, and everything required to power the front I/O.

The chassis comes with their built-in fan controller, which comes with two fan rails, each with a control switch for performance and silent operation.

There are push out cable routing holes too. You can leave them in like this, or squeeze them together, push them through, and create an additional routing channel.

There are two 3.5″ drive mounts in the base of the chassis. Ths whole bay is removable too, although at this point, let’s just point out that pretty much everything can be removed if you want to.

The PSU mounting space is vast, and since the chassis is long, that’s hardly a shocker. Mounting a huge PSU won’t be an issue, and you can easily accommodate a lot of excess cables down here.
