Don't know if you can see it, but it's that tiny little metal tab above the expansion slot. I'm not sure exactly what thing is there for but it was easy getting it down.
And is it normal for the back i/o plate to convex like this? Not a big issue but a bit annoying.
Unless you're doing the spread method(and even then really) you should only be applying the TIM to one surface. The CPU is more logical for line and dot methods since you can put it directly in the middle of the CPU which is the one place you really don't want to be missing any TIM. The edges are not quiiiite as important.
Also, yeah, I do sometimes worry when first applying TIM on a new chip or newly lapped surfaces about it...leaking down....i think you said a few pages back. Even if it's not electrically conductive(and really be careful it is lol) you can have TIM spread out from the middle and flow over the edges before it's done spreading and having it get on one of your cpu pins or in the sockets will probably stop you from posting on your next reboot. Cand be a pain in the ass to clean =)
As for the little tab, if I had to guess maybe your case can come with or be 'upgraded' with a screw-less style pci slot retention system. Those are typically secured by a small piece of metal you leverage behind a little tab...usually right about where that one is =)
Your backplate should 'normally' not be warped in any way and can take longer than you'd think to install with certain combinations of hardware. Was it warped before you installed it or did you just notice after screwing down the mobo that it got tweaked? I have seen it happen a lot when people paint their cases and either don't sand enough first or go crazy with the spraypaint layers and shrink the size of I/O cutout so the plate no longer fits right. Sometimes that can cause problem like shorting out the motherboard or other really wacky stuff sometimes but whenever I hear of it being a problem it's usually debilitating so I wouldn't worry about it if you were able to boot up fine and all your hardware seems to be working correctly.
