I recently bought 16GB (2x8GB) of 3000 MHz DDR4 RAM second hand for my server so that I could swap out the 32GB (2x16GB) of 3200 MHz DDR4 RAM and put them into my new gaming rig.

Final hardware config: https://pastebin.com/3uFXuPht

Now I just have to figure out whether I want to get another external soundcard for my gaming rig or if I can live with switching the USB cable back and forth between the two PCs or if I can get used to control the volume with software. I really like hardware knobs though…

Anyway…

What - if anything - do you insist on buying new and what do you buy second hand and why? Personally, I could buy any component second hand, provided I’m allowed to run my own test on it first.
