Bag
Very good quality case, aesthetically perfect compared to others. The interior storage compartments are well proportioned and do not protrude into the main laptop compartment. However, my laptop is a 15" and I agree with some of the comments. I was right to take the 17" version so that I could fit it inside without any problems. At the same time, my PC is bigger than the standard gamer PCs, so it has bigger fans.
I recommend this article, but be sure to measure your PC carefully to see whether it's a conventional size or not.
