The Cougar QBX is a lovely SFF. I've not but a new PC for over 10 years but after seeing what small components are available these days I just fell in love with the looks size and features of such a small case.
Interestingly one thing led to another and I was adding components along the way including aRGB lighting which I never thought of initially.
Let me know in the comments if you have experience with this case and what you think.
