Dell Precision 7720 Refurbishment/Upgrade Project

[Will]

Ever since I found out about mobile workstations, I've always wanted to have a Dell Precision 7720, both because of its design, which I personally think is really cool (especially its internal layout), and because its the last Precision with an MXM slot before Dell switched to the DGFF format starting with the 7XX30 series. Then one day, while browsing OLX, I was lucky enough to find a Dell Precision 7710 for a low price. The laptop was listed as "for parts" and untested, and its specifications weren’t provided, but from the pictures in the listing, it was clear that many parts were missing, such as the heatsink + fans, keyboard, RAM, SSD, AC adapter, etc. Even so, I thought it was a good deal, so I bought it. Here are the pictures from the seller:

 

I believe this will be a very interesting project, so in this thread I will post the progress of my journey in refurbishing/upgrading this amazing machine.
