Oh my God, yes they are. I had to get a vertical GPU mount. Okay, so I got one. And I'm going to show you pictures of how it looks. :D
Doesn't it look so cool? I Can't get over how cool it looks.
Close up of my setup with Vertical GPU Mount <3
I had to cut off the horizontal dividers to fit it lol. But it was worth it!
Full picture of my setup now :D The fans don't spin at idle. But you knew that already. :D
