This is an amazing case and I bought it several months ago. I like that it's huge, I like the aesthetics of it -- it literally looks like it came out of a Tron movie. Very high quality parts, and incredibly modular. In this situation, I got what I paid for, even from a build quality only perspective.
The reason I like big full sized cases is a valid one. I generally don't move my computer, and I like having options for installing things. It is definitely big and heavy, but the aluminum handles allow for easy pickup.
Rewind to 1997 -- I built my first water-cooled case. Got the distilled water, put in the powder, overclocked my Celeron significantly and all was fine. 1-2 years later, my computer started overheating. The pump was fine, but upon closer inspection discovered the entire circuit had algae growth in it. Then I meticulously disassembled it, and attempted to clean it. There was no cleaning that out. It was done. So I decided I'd never do that again.
But as a result, I found that sizeable aluminum cases act as great passive cooling, so the inside of your computer can dissipate far better than a smaller case. Get some quality fans, and you end up with a quiet rig. In the early 2000s I bought a nice all aluminum silverstone case, and that lasted me until I bought this one. The case predated 2.5" drives, didn't have the fancy rubber vibration dampening, and had headers for USB1.0 probably. I had additional problems where my Intel 4790K with a nice big coolermaster heatsink on it, was too big for the pull out tray, so I had to install it the old fashioned way.
