I dunno, I would class this as easy peasy. One captive screw. No need for tool to remove ram, it pops up when you flex open the metal bits. Doing it with fingers is way easier.

While you can remove the 4 screws to remove and transplant the bit of plastic onto the new drive, a dab of sugru to secure 20 quid ssd drive will do the job. Upgrading these things tales less than 5 minutes.
