I have the original 932 and totally like it. I've had it for about three years. My daughter has a bit of a hand-me-down PC that I've upgraded piece by piece. She has a mid-tower Antec case that is made of decent material, but I'd like to upgrade someday. It has poor airflow. The case used to be my dad's and he had a few component failures that happened sooner than they should have. My suspicion is heat. Anyway, since I like my HAF 932 a lot but my daughter only has one hard drive and a smaller desk, I have my eye on the HAF XM. I'm confused about the dimensions. When I compare them to the 932 or the full-size X, the XM isn't much smaller. It's like, an inch shorter. Really?! How does one inch shorter than my monster case make it a mid-tower? My case is so huge that I'd still call it a full tower if it was an inch shorter! I even plugged the dimensions into this sizing aid site and the XM was barely smaller than the 932 or the X. Am I doing something wrong?
