I have a 2012 GAZP7 that is still chugging along nicely, except for the fan noise and heat :) Other than that, I love it.

I'm looking to upgrade the memory from 16 GB to 32 GB. I know this is possible, and dmidecode shows there should be 4 slots, but I only see 2 when opening up to the motherboard.

I also don't see where the second hard drive is...

Advice is welcome.
