I wanted to do a build with the new Haswell CPU. I used a case I already had on hand--the Cooler Master Enforcer. Love that case; I've done three builds in it. But then discovered that the liquid cooler I picked up at a good price wouldn't work, so bought a new case: the NZXT 420 Phantom, and re-built in it. I purchased most of these parts over the past 6-8 months looking for good deals (made some--missed some) and just waiting for the Haswell to come out.
The ASUS motherboard is too expensive, but has tons of features. I'll be playing with it for months. I'm still saving/waiting for a good deal on a graphics card.
