Is the chasis for Razer Blade 14 2017 and Razer Blade 14 2016 the same?

Hi,

I got a Razer Blade 14 2017 at work. It's a pretty cool laptop, but has some issues. It's a bit worn out, the speaker grids have become loose and the screen has a couple of dead pixels.

I saw a guy selling a broken Blade 14 really cheap. The problem with his machine is that the motherboard is fried. So I was thinking of getting it and fixing up my laptop.

From the photos it looks identical to my machine, but do you know if that's the case. Will I be able to replace the bottom lid of my laptop with this one?

And another thing. His machine is the touchscreen, 4K version. While my machine is the Full HD version. Will I be able to simply switch the screens? Or are they not compatible?
