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.


I agree! In addition to hard drives I’d also rather buy motherboards new, since a lot of electronics are directly exposed, and I trust only me and myself in adequate handling of such delicate stuff. XD
A lot of high end boards have basically a shield around the entire top side which is nice for that. But I have had a few boards fail over the years, and all high end ones.
I have only ever used midrange B550 AMD chipsets, so I don’t know what that looks like. But I do wish to someday have one of the X-something AMD boards :D still AM4, mind you.
