No Idea what I am looking at.
Hmmm, I will take another picture when I get home. But the black metal piece that holds the case fan on my machine looks nothing like that picture. Mine has one large tab that extends out to the front of the case and almost touches the red SATA cable going to the cd drive. And on the other side pointing to the rear of the case are two smaller tabs that interfere with the PSU locking mechanism.
The computer came with the tabs installed behind the silver part of the actual chassis. But the tabs still interfere with locking the swing out PSU in place even with the bracket tabs behind. I moved them in front to make it easier to picture. And to see if they wouldn't get in the way in that position, but they still do.
If you look closely at the second picture you posted, the black bracket is actually not supposed to even be there.
Looks like I got an unnecessary bit of metal that's just getting in the way. With out the fan in, the PSU locks into place with no issue.
I've been in contact with Dell and they are sending a tech out with a new fan. Not that I couldn't have just replaced the fan myself if they would just ship it to me, but they want to see what's going on with it themselves I suppose.
The fan unplugged from the mobo and removed from the chassis. You'll notice the black tab on the right, mostly blocks the screw hole in the silver bracket that actually mounts the fan to the chassis. You can access it thru the square hole, but at an angle. Which still makes it awkward to get to. I must have dropped the *** screw a million times while trying to figure this all out.
The fan split into its component parts. The black part appears to be completely unnecessary for this model chassis.
