Looks professional. Everything fit. Air flow is very customizable. You can put a fan anywhere, and if you're really into it, your own foam air guides for maximum clean air flow, and look.


Understated good looks Nice cable management It works!

The case is very cheap, so if you need several to build multiple PCs, this won't cost you a fortune. I bought 3 to build render nodes for Blender. They looked good when placed together. USB and power buttons are on the top of the case. There are cavities on the side panels to help with cable management.

The previous O11's were fantastic in their design, but a true full tower one was necessary with 140mm fans everywhere. All the little improvements add up. My RTX 5090/9950X3D rig stays very cool. HUGE bonus that I absolutely love is the removeable motherboard tray. It's a test bench, almost! (Anyone remember 3DGameMan saying "unfortunately, the motherboard tray is not removeable"? Well, this is! The PCI-E slot clamp design is genius. Two very simple "doors" that clamp down. No noticeable GPU sag on my massive card. The extended connectivity of USB, audio, and drive storage is brilliant. Open mesh on the back for CPU and PSU cooling is very nice. I love the fan filters on the top and bottom of the case. Easy to access.

I received the newest v4 bracket and the shipping was fast only took a week and a half to get to my house from Hong Kong


- Looks like a more expensive case when finished product - Despite molex/low quality fans, they do have ARGB/5V connector and motherboard control capability - Cable management is actually quite good, with ample cutouts and plenty of room in the rear compartment - Roomy interior for a MATX, can fit decent-sized GPU and/or AIO or additional fans - Very easy to build in

It comes with ARGB fans and hub

The lian li a3 is cheap for someone who cant afford ITX and it is perfect for someone who needs a small and affordable pc build

REALLY LARGE AND INCLUDES ALL THE ACCESORIES NEEDED, PREVIOUSLY MOUNTED 4 ARGB FANS AND WHAT I MOST LIKED IS THAT ALL THE CASE HAS MESH PANEL SO IT MANTAINS AIR FLOWING WITH REALLY LOW TEMPS I GOT THE PSU INCLUDED ON THE PRICE SO ITS A STEAL OF A DEAL

Gotta love this HUGE case. Came with 4 160mm fans so its very quiet. My temps are the lowest i've ever seen. Lots of space especially if you're looking to make an water-cooled build. Very cool looking front RGB. I wish there would be a black and white color variant and would easily look like a stormtrooper!


Looks good Great cooling potential, noticeable temp drop from old casing Can fit 9+ case fans. USB c compatibility Great cable management built into case





Quiet psu Quiet aio Sleek case
