Got mine in. I have four plastic washers, and some sticker things that seem to have no purpose. The four screws on the side, and the two on the back squish the plastic in and distort the shroud when screwed in all the way. (the rear plastic distortion is really bad)
There are not enough plastic washers to cover all the problem areas, if that's what they are for.
A shame, but I guess you don't notice it when it's in the case.
All in all satisfied for $6.....I guess
