  • Satisfied with the product.
This Lian Li Case is really great. Didn’t have any problems assembling parts to it even though it is my first time building a PC. Very spacious, I have 8 fans 120mm inside and the case still has space for more. I would say that is friendly for beginners.

  • Great case
The media could not be loaded. My teen is putting together a pc. He loves this.

Very good case! It's quite spacious, flexible in how you want to build, and sturdy. Highly recommended!

  • Phenomenal Case
Absolutely fantastic case. I will NOT fault this case for its size as some do, because that’s precisely why I bought it. It has amazing cooling ability and has tons of room to work. Solidly built and worth its price. Highly recommended.
