Re: Why so traumatic? Since you ask
The system I am typing this on is a somewhat elderly - 4 years ish? - home build put together as follows :-
Gigabyte motherboard
Intel i5-2500 @ 3.3 Ghz quad core chip
Nvidia GTX 550 Ti graphics card
1Tb Western Digital system disc (Spinning tin - have not gone SSD yet)
2Tb W.D. data hard drive (manual switch, not powered up on boot unless I think I will need to access it)
24 Gb RAM (I use CAD and play about with virtual machines)
all running Mint 18.3 Cinnamon 64 bit V3.6.7 on 4.15.0-29 generic kernel
In other words, absolutely nothing special at all. Hope this helps.
