I love the design of the Air 540(great for cable management, direct airflow, shows only what I want to show.) It seems to have a lot of plastic though, which is sort of disappointing, a more expensive model with less plastic would have been good.
Pre-Ordered the Air 540 a few days and this morning got an email from Amazon: " Estimated arrival date: June 28, 2013 - July 12, 2013"
I think I am tired of full tower cases, unless I wanna do quad SLI, I will stick to smaller cases from now on.
