No screw to support video card?

Haha, what was that about cheap?

Sigh.

The plastic thing's lock go to the right of the screw, top photo...

Yes, you're right. The ones that came with the case (an odd number, so he lost one?) are "locked" into position in un-used drive bays lower down, so it was pretty clear how they work. They have prongs that are spaced exactly the same as the threaded holes in the drive, so also pretty clear they poke into those holes to hold the drive in place.

I'm no expert in assembling current PC's, but I could figure that out - which, yes, makes me worry about this guy doing it "professionally"!
