be quiet Light Base 900 FX Case Review – The Ultimate Display Case!

A Closer Look – Interior

The benefit of such a massive PC case is pretty obvious, you quite simply get a lot of space! When it comes to the best gaming hardware on the market, it’s often pretty huge. The flagship RTX 4090 graphics cards are absolutely ridiculous in terms of size, but without a doubt, they’ll fit in here with a hell of a lot of room to spare.

The case supports literally any motherboard, from mini-ITX, which would look hilarious, right up to the largest XL-ATX and E-ATX motherboards and dual socket workstation motherboards. Then again, that’s hardly surprising given the size of the damn thing.

What’s really trick is that it supports both traditional cable routing options, with a plethora of cable routing cut-outs around the motherboard with massive cable grommets to keep everything looking smart. However, there are also additional cut-outs for motherboards with rear-mounted connectors, and with the growing popularity of Behind the Motherboard (BTM) designs, it’s great to see be quiet! giving you the best of both worlds here.

There’s a built-in anti-sag arm too, which is designed to still offer GPU support in both vertical and horizontal orientations.

The rear PCIe slot covers are fully removable too, allowing you to install the optional vertical GPU kit (sold separately).

But you can see a stock image of how this installs below.

Obviously, with glass in the front, you’re not going to get any airflow from there, but at least you’ll get amazing views of your gaming hardware.

However, as you can see, there’s room for fans at the top, bottom, side, and rear of the case, so you’ll not be left short on airflow here. Naturally, there are dust filters on every intake too, so keeping your PC clean should be a breeze. The fan mounts are all removable too, just two thumbscrews, take the tray out, fit your hardware, two thumbscrews to put it back in the case!

However, the FX version comes with four pre-installed Light Wings fans, while the DX comes without fans so you can put your own mark on the build.

What’s really surprising, however, is just how much space there is in the front of the case. That may sound obvious at this point, but this is a dual chamber case, so there’s a lot more going on around the back, so let’s take a look!

Behind the motherboard, there’s a large chamber to install your PSU, with larger ATX power supplies being easily accommodated.

There’s a vertical panel that covers the cable routing but also helps ensure airflow from the side fan/radiator mounts is better directed throughout the case.

However, this panel is hinged too and can be opened out to better access the PSU mounting area and cable connectors for your motherboard.

Back here, there’s plenty of room for storage too, with a hard drive cage mount below the power supply mount, and SSD mounts on the vertical panel. It’s all fully removable too should you want this space for other shenanigans, and it can support an additional cage (sold separately) should you need it. That means as standard it supports 4 SSDs and 1 HDD, but can be expanded to support 6 SSDs and 2 HDDs.

Got fans and RGB? I’m sure you do, and you’ll find two of these hubs in the back, one in the bottom and one in the top, all paired together already, and only one SATA cable is required to power them both.
