Review: Big bang for small case - 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. *Update* In case anyone is wondering, YES. It DOES fit an Astral 5090. I pulled my 9070 XT out of the case just to fit test and it 100% fits and has room for the 12VHPWR connector adapter.
Review: Great case for my simple build. - This Lian Li case is the perfect fit for my build. I watched many build videos for this case and decided on ordering it but wanted a black one but it wasn't available at the time. I was a little scepticle if I would like the white one but after building in it it looks great on my desk. 1 fan under the video card and 2 exhaust up top (center and rear) and it cools well. Not much room for cable management but doesn't matter as you can't tell through the ventilated side panel. Glad I got the white. Simple build with Ryzen 3600 and GTX 1060. Stock wraith cooler looks good though ventilated panel. Great case.

### ⭐⭐⭐⭐⭐ Easy, high quality, good looking, not too expensive
*by E***T on December 17, 2025*

For too long I kept the old tiny (and ugly as sin) case my PC came with. I stare at it every day. Life is too short for a cramped, ugly PC case, so I got this case. It’s extremely adaptable and user friendly to work in. (I had to move power supply to the side due to the length of cables with my SFX power supply.) Bonus: it looks really nice! The mesh cooling works insanely well. Currently cooling 175 watt GPU + 65 watt CPU (continuous load all night) with a SINGLE 90mm rear exhaust fan (!!!!). [I also had to flip the Noctua Ghost CPU cooler 180 for fit reasons, and I didn’t have extra thermal paste-so I just used the old stuff—NOT ADVISED; just FYI to add context to how well the case is working.]
