My 2 cents - heat causes a lot of damage. On my desktops, I have dedicated fans (took a little cutting of part of the case) for the hard drives. Keep them running cool - any electronics for that matter - and they last longer. On a laptop, I noticed that newer versions have vents at the bottom. People like the sleek look but that also leaves no place for vents since people won’t like the vents upwards (plus you need space for the keyboard). My work laptop is like that - added to that runs Windows which makes it run hotter. I elevate the farther end with a box (even a pencil will help) which allows more heat to escape.
You don’t have to sell your PCs in 3-4 yrs - just accommodate for bad case/frame designs and/or avoid using OSs that unnecessarily tax the system.
PS - Aravisian’s Disk Digger recommendation made this poster happy: Help Pls... Zorin Os detects extarnal Hard disk but cant acces it
