I posted this on DIYC.com, but thought I'd share it here just to give a visual for everyone.
The F4V2 will definitely fit in a CG500, but it wouldn't really give room for a PSU. This isn't a problem if you're using power injection/distribution boards. The board will mount directly to the far left holes in the CG500 if you don't plan to make a mounting plate.
And of course there's more than enough room in a CG1500 with a PSU in there as well. Also, the board mounts directly to the case of course.
