## Customer Reviews

### ⭐⭐⭐⭐⭐ Big bang for small case
*by A***R on July 27, 2025*

Got this case and was excited to put together my own small form factor build. It is super easy to work with. Just keep in mind it is a small case so it is definitely going to give you a bit of a brain puzzle for managing cables and getting everything to fit. If you are going for an ITX board with a AIO on top, I would recommend sticking with a slim variant as I ran into ram clearance issues; I opted to pit it on the side and add 3 exhaust fans on the top to help promote the original airflow design. I currently have a 360mm AIO a 9070 XT GPU an SFX PSU, and managed to still add 6 additional fans inside the case. I use this for my entertainment/VR build and it is doing perfectly fine without issues. Easy to work with, great build quality, love the air flow and room for fans and ease of access with the side panels popping off so easily, but staying locked into place securely at the same time. It also looks great in my living room with the black finish and wood accents. I'd also highly recommend looking at GamerNexus' review of the case to get an idea of how to get the cooling solution right if you are seriously considering this case; they helped a lot with my design choices.

### ⭐⭐⭐⭐⭐ Excellent mATX case with plenty of room
*by J***N on July 22, 2025*

Not a small form factor case by any means, but if you want something compact that can hold an mATX motherboard and full-sized ATX power supply, as well as excellent GPU support and still have room for 3.5" hard drives, this is the case to get.Lian Li makes incredibly easy to assemble cases packed with accessories and this is no different. Installation was a breeze and temps are super low (currently running a 12600K and RX 9060 XT 16GB), as is the noise level. The only downside is the lack of cable management, but if you're buying the all-mesh version, that shouldn't matter too much.

### ⭐⭐⭐⭐⭐ Amazing case.
*by K***Y on July 21, 2025*

Beautiful case and quite interesting to build into. I got the mesh one with the wooden front panel and it’s been working amazing. Very good cooling due to great airflow. The hardest part is managing the cables. It’s very crammed without space behind the motherboard to manage cables. The power supply mounting is quite interest and I think works out very well because of the included angle power adapter. The noise level is decent, since it’s very free flowing. I’m able to tune my fans on my 4080S and my 240AIO and this thing runs with very low noise while playing games.
