I've picked up a Toughpad H2 cheap to play with and looking to upgrade it a bit. It's health H2 model so I am guessing no gps in it, it has i5 2577m 1.7ghz with 4gb ram and a 160gb drive. Have got an ssd from my old Lenovo x61 that i'm going to chuck in and i'm looking to upgrade the ram, I know it will take 8gb easily but I did see someone say they had 16gb, would this work on my model or was that in a later model? Anything else that I can upgrade easy enough? Will be looking at putting in a gps module, maybe shoud have waited for one with one, but it was a price I couldn't say no to really. Has anyone put windows 10 pro 64bit on an h2? it comes with 7 pro 32bit.
