Lian Li has done it again! This time they have excelled in creating a functional yet stylish case and improving it even more. The Lian Li O11Dynamic XL Midi-Tower combines brushed aluminium with tempered glass elements. The dimensions of the case are designed so that even the huge EEB ASUS ROG Dominus Extreme motherboard with Intel's C621 chipset and Socket 3647 for Xeon processors will fit with the assistance of an additional accessory (available separately). What Lian Li have retained here is the broad dual-chamber design, which offers plenty of space for high-end gaming components as well as excellent cable management options. The options open to users when it comes to air- or water cooling, it goes without saying, are second to none.

Nice spacious case to work in. Not convinced by the LED for the power switch but just missed those headers out.


December 2020

Absolutely amazing case, super spacious and easy to work with and cable manage with the dual compartment design. Quickly delivered by CCL when another supplier had previously let me down.


November 2020

Lovely case lots of room and lots of choices on how to build in it. I have 10 fans running and still have room for hard drives ssds and moor. Very happy.

Beautiful and very customisable case. Cant wait to start building it once I have all my components. Arrived sooner than expected which was a plus!

the case came sooner than expected. & as this is my 1st lian-li case i was a cautious, so after doing my research over youtube & setting my heart on this case i was not disappointed. its pretty sturdy my only gripe is with the thin bar at the back for the extra 2.5" drives as it could easily bend ( well i think so anyway) but overall the case it excellent quality with plenty of room for both air cooling & water cooling builds. Also in the back there is plenty of room for cable management & a couple of extra fan/lighting controllers.

It is,the case of dreams and is awesome in many ways in terms of hardware sleek features and a bit of the rgb lighting to go wen this is all powered up and fully built it is a power house of a system!!!

Brilliant case that will no doubt go down in history with legendary status. Easy to work in and top class Lian Li quality that we have come to expect. Although clearly designed with watercooling in mind, it also performs nicely with air cooling or AIO. Note of interest. The Noctua NH-D15 air cooler WILL fit inside the case, but if your motherboard has one of them big, built-in IO shields you will have to remove one of the 140mm fans off the cooler and replace with a 120mm fan. I tried it with an Asus ROG Strix X570-F motherboard and Trident Z Neo ram ... Had to replace one of the blowers with a 120mm to make it workable. I personally have it running with a 360 AIO now and am very happy with performance, even though I will still be saving for a custom water loop though in the future. Been draped in glass and brushed aluminium, it is a proper finger print magnet, so if you are a bit OCD like me, get the micro-fibre cloth ready! 10/10 case, if in doubt - buy it.
