Lian Li PC-O11DX Dynamic Midi Tower with Two-Chamber Design Reviewed

In Zusammenarbeit mit Profi-Übertakter Roman "der8auer" Hartung!

Design

Let’s get to the design of the Lian Li PC-O11 Dynamic. The left side and the front are made of real glass, while the rest is mainly made of steel. Only the trim strip on the front, which also contains the I/O panel, was made of aluminium. The overall impression is that the case is very robust and stable, but due to the selected materials it also weighs just over 10 kg.

The glass panes have black frames and are simply hung into the housing by invisible mounting hooks on the back. Very successful solution as we find, since no tools are needed and the clean impression is not defaced by ugly screws. The I/O panel of the Lian Li PC-O11 Dynamic is equipped with one USB 3.1 type-C port, two USB 3.0 ports and the usual audio connections.

Since the case has a two-chamber design, it looks different on the back than expected. The slot for the power supply is located next to the slots for the expansion cards of the mainboard. Directly above is another slot, which can be used either for two 3.5-inch drives or alternatively for another power supply. A second power supply could be especially interesting for overclockers or very complex custom water cooling systems.

The lid of the Lian Li PC-O11 Dynamic can be easily removed by removing two screws without tools. Below it, a magnetic dust filter is revealed, which lies above the mounting slots, which can accommodate either three 120 mm fans, two 140 mm fans or radiators up to 360 mm. At the bottom of the case there is a very similar cutout including a dust filter, which of course is meant for the same number of fans or radiators.

Let’s get to the interior of the Lian Li PC-O11 Dynamic. In order to get to it, the cover must first be removed, which is only fastened with two knurled screws. Then the side panel on the back and the panes on the front and left side can be lifted out upwards. You already have access to all sides of the case. Due to the two-chamber design, the main chamber is quite empty without a system, because only the visually impressive main components such as mainboard, graphics card, cooling and, if required, two SSDs are to be seen here.

If you turn the case over, you get a view of the power supply slot and other possibilities to install data carriers. The cover in the middle has several direct functions. On the one hand you can store all possible cables behind it and on the other hand it can hold another 3.5″ or 2.5″ data carrier. This cover is cut somewhat narrower at the bottom so that the main power supply has enough space and can be dimensioned accordingly. Here one notices that Lian Li and der8auer have certainly thought about it and wanted to use every centimeter optimally.

A special feature of the Lian Li PC-O11 Dynamic is the offset mounting position for the cooler on the side of the case. This should allow the space to be used optimally again. Due to the offset, a total of three 360 mm radiators fit into the housing. Normally they often get in the way at the corners, but this is not the case here. In addition, large or long graphics cards can still be installed, as these are not disturbed by radiators etc. in the front.

In the main chamber, the eight slots for mainboard expansion cards are protected by reusable covers. Directly above is the only obvious Lian Li branding inside the case, which comes in the form of a silver aluminium badge. Since Roman “der8auer” Hartung helped a lot with the design process, his trademark will of course also be presented here. Even a little higher, additional fans can be installed in many housings. However, this is not the case here, as Lian Li also leaves room for possible equalizing tanks of a water cooling system. Alternatively, 80 or 90 mm fans may be installed. Unfortunately we couldn’t test this, because we don’t have such a fan at the moment.
