Built a new system for a relative today. This one went MUCH more smoothly than my system in 2014 did -- because I stopped playing around with MicroATX and used an ATX mid-tower this time. I love. This. Case. So easy to work with, and I could finally do that "route all the cables behind the motherboard" thing that everyone keeps talking about.
This was a wonderful case to work with. That's half the battle with these builds. Lots of space behind the motherboard tray, generous cable grommets, removable drive trays, lots of space. The Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case gets my seal of approval.
