Medion P6705 chassis replacements

[Ezenia]

Hello,

So it appears my Medion P6705 (MD61366) is beginning to fall apart. The 1st issue is on the back cover, some of the screw holes at the top that go into the hinge have failed. The screw goes in, but doesn't stick, so even if it's screwed in, the back cover is still loose in that area. The material that's supposed to hold the screws has broken off. 

The 2nd issue is on one side, the hinge no longer screws down because the plastic mounts have broken. So I'm basically in search for chassis replacements. I've looked on the Medion spare parts page and can see some chassis replacements. However, there's no picture for the parts.

What parts do I actually need? Bottom cover and bottom case? I want to make sure before I buy because there's no picture to see if it's actually the part I need.
