This is an great case for the money. Build quality is good, the case has a good solid feel without being too heavy. I liked the magentic strips that hold the glass panels in place whilst you fit the thumbscrews.Tray mat on top also held with magnetic strip. Good choice of pwn fans which are quiet and efficient the lighting options are excellent.
Like all things there some,minor, problems. My Zalman power supply( getting a bit old now) was too long and didnt fit and I had to remove the drive carriers to get it in. Not a great issue if like me you have m2 and ssd drives. My Asus 970gtx graphics card would not fit in the vertical position as it would be right up against the glass panel and not cool properly. Bought an aftermarket rig to sort that, Also the smartcase lighting controller didnt work, but after a few emails and tests, Corsair replaced it.
Overall though it's a very good case for the money, well worth considering for your custom build.
