Many people seem to ignore the fact that its a 3.7l case :D I love small PC's. My PC case is 20l with a 4070. I could go down to maybe 15l if I wanted but that would be pushing it. This thing is small af!
You can always build a PC yourself. You wont be able to get it this small with the same performance.
Not gonna buy one, but I just think its neat!
