If you’re the type of PC builder who’s never quite happy with the features of any case, or you want a chassis for your rig that can grow and change along with your evolving rig, Lian Li’s O11D EVO might be perfect for you–so long as you have lots of space.

The Lian Li O11D EVO is, as you might guess, an evolution of the company’s 2018-era O11 Dynamic while incorporating lessons the company learned from subsequent chassis like the O11 Air Mini and the O11D XL. It definitely leans toward the latter in terms of sheer size, at 18.07 x 11.22 x 18.31 inches (459 x 285 x 465 mm). So you’ll either need a big desk or a fair bit of floor space to accommodate this case. But otherwise, the O11D EVO is all about morphing to fit your needs. It will also ship in both black and white options.

Out of the box, the case can be configured to accommodate up to E-ATX motherboards (with a width of under 280 mm) in a fairly standard orientation or reversed so that the glass side panel and motherboard live on the opposite side of the case. And the front-panel IO can be moved as well, giving you easy access to two USB-A, one USB-C, and an audio combo jack either up front or on either side of the bottom of the case.

However, that’s just the tip of the transforming iceberg. Lian Li will also offer up five kits for the O11D EVO, letting you move the front IO to the top (where it honestly should be by default on a case this big); replace the front glass panel with mesh for much-improved airflow; or double up on those front-/side-facing USB A/C ports (although you’ll need a motherboard two front headers for that). There are also two separate kits for showing off your graphics card. The Vertical GPU Kit (somewhat confusingly) lets you mount your best graphics card standing up but running horizontally, from the back of the case to the front. The Upright GPU Kit houses your graphics card in a true vertical orientation at the front of the case.

In short, the O11D EVO is more of a case platform than a traditional chassis. So it may be the best PC case for those who like to continually tweak and reconfigure their PC. And at $169 US ($159 in most other countries), it seems reasonably priced, given you also get a tasteful RGB strip that runs down the front. Note that the white model will sell for an additional $10.
