This specific version is excellent with ATX PSU support. Mesh front is brilliant, I've installed an RTX 4090 + i9 inside without any thermal issue. This specific version is excellent with ATX PSU support. Mesh front is brilliant, I've installed an RTX 4090 + i9 inside without any thermal issue.

This case is an awesome upgrade! Lots of space in the rear compartment for cable management and tons of airflow options. Case looks fantastic with that Lian Li aesthetic and the build quality is amazing. I did have a little of difficulty fitting 140mm fans on the top and bottom brackets due to clearance with the vram heatsink and cables so I would recommend 120mm for these areas. The included 2x 140mm and 120mm pwm fans are a great addition. Overall I am super happy with the case, I would definitely recommend! This case is an awesome upgrade!

Extremely good case. No issues with cable management and setting everything up is fairly intuitive. Downsized to this from a full tower and despite being a smaller case it feels 'roomier' Extremely good case. No issues with cable management and setting everything up is fairly intuitive.

I was the very happy owner of a previous Lian Li case, which prompted me to look out for another one of their cases when looking to update. I picked this one based upon its generally good reviews, price, and size. The construction is pretty good, good strong aluminium, well ventilated, good built-in fans, plenty of space for longer GPUs.

There are however, a few things that I found difficult to work with. The worst was the SSD storage areas have a big flaw when used with my power supply's cables - the cables must be flat, whereas the ones with my power supply have the wires connected at right angles, meaning that the wires would get bent if I forced them in. This ended up with me needing to use the extra HD/SSD cage which doesn't have the SSDs flush against the panels.
Other inconveniences include needing to take the top panel off in order to open the glass side panel, the fact that the screws were so tight that I nearly ruined the screws trying to unscrew them (in fact, there are a couple that even with the help of my electric drill I haven't been able to unscrew, including the one that allows you to change from a 7 slot to 5 slot layout. It would also have been good to have thumb screws on the PCIe slot covers, rather than normal screws.
I've had this case for about 10 weeks at the time of this review. If all of my components were the latest, I'd probably have a much more positive view of this case. But as a few of my components are older (e.g. power supply, using 2.5 inch SSDs instead of NVMe), it's not quite so well suited.

The case is a great size, plenty of room for larger cpu coolers. Just using the included fans keeps my noctua DH15 cooled 5800x3d and 3060ti running VR sims cool as.

Super solid case, great quality, and fans are super quiet. My Strix 3080 fits in well with heaps of airflow to keep it cool.

Just remember to check the outer dimensions, because it isn’t quite as mini as it looks Super solid case, great quality, and fans are super quiet. My Strix 3080 fits in well with heaps of airflow to keep it cool.

Downsized from a 780t, more than happy with this case. It's a bit bigger than anticipated but still a great downsize Downsized from a 780t, more than happy with this case. It's a bit bigger than anticipated but still a great downsize

Case is a pleasure to build in, and quality/rigidity is decent.

Slightly larger than expected for a "Mini" - but completely the fault of my minds-eye for mentally measuring based on the dimensions.
Maybe be prepared for that disillusionment. Case is a pleasure to build in, and quality/rigidity is decent.

An excellent case for the price. Very flexible setup, good quality and quiet fans. An excellent case for the price. Very flexible setup, good quality and quiet fans.

Airflow was the reason I bought this and it really performs well.
I love the room allowed for cable routing. Makes it easy to create a really tidy build Airflow was the reason I bought this and it really performs well.

Lots of modularity, easy cable management, looks great. Overall an amazing case! Lots of modularity, easy cable management, looks great. Overall an amazing case!
