So I bought an SSD for this machine in November, and ordered the enclosure recommended by TheShortTimer here off eBay. I finally had time to install the SSD in the enclosure today. No problem with all but two of the screws. Per the picture, I think I know where they go, but they don't want to go all the way in. Also, they don't look like they really serve any function. Are they there as a potential attachment mechanism if needed, but not necessary to install otherwise?
