A late review of the be quiet! Pure Base 500DX case I got for my kid's computer, though it's housing mine currently as I wait for my CPU RMA (since almost all the hardware in it is becoming his after that).
I really like the case, it's nice and quiet and has good airflow. Pretty easy to work in (though my previous case was a gigantic Fortress FT02 so it feels a lot smaller because it is), lots of cable routing ties and even my older stiff power supply cables could be routed through all the intended places with enough room behind the motherboard it's not a huge pain to get stuff flat enough to fit the side cover on.
My motherboard doesn't have any kind of RGB controller but the built in patterns are nice. I moved the top fan to the front after watching Hardware Canucks' review of the case, seems to be fine.
Will play around with some stress testing to measure full load temps but under no load it's as quiet as my FT02 was (and the FT02 had 3 180mm fans on the bottom running slow to feed quite a bit of air but stay silent).
Overall much happier with the case than I am with the Dark Rock Pro 4 cooler.
