Level 10 is only ATX/mATX, doesnt support watercooling (at the price point its listed at thats pretty rough...), no side window as mentioned, low quality front bay covers, not quite as easy to set up as a conventional case. Its huge, its heavy and for a case of its price, size and weight doesnt offer near the system space it should IMHO. Your trying to compare 2 VERY different cases, which are kind of meant for 2 separate markets. If your happy with your level 10 then thats great for you, I personally like the murderbox for its space, cooling options, layout, and craftsmanship. I plan on taking my time and enjoying the process of putting together the computer that will be housed in this beautiful case =D.
