For whom it may concern

I built my current PC in 2012 as well, though it took until 2015 before I started to use it daily. I was too lazy to migrate from my older PC, until it stopped working and I had no other choice. Just like you, I have upgraded RAM from 8 to 16 GB, otherwise no changes and I only have a traditional HDD.

 

I don't have any plans to upgrade rest of the hardware though, more likely I'll get myself a better laptop than the one I currently use since it has begun flickering the display and is dog slow to use.

Exchanging the hardware was the expected quite easy task. Took me an hour or so. Now I am only missing an extension cable for the front USB 2 ports, because for whatever reasons, the header on the new mainboard is far away from the USB 3 header. And the split off cable is quite short.

 

At first I couldn't get my the internal GPU working in parallel with the dedicated one. I had to remove the latter, reboot and reinstall before Windows allowed me to use my two displays and the TV together.

 

Setting up the software in an ongoing task with some hiccups here and there...
