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 don’t know what you’re doing, but if your headphones are using a 1/4 inch jack or 1/8 inch jack and your devices have some form of audio output already, you can just use a plain ol’ analog mixer. That’ll give you knobs and let you hook multiple devices up.
I keep my headphones plugged into one. I rarely actually use the other devices, but sometimes I’ll want to be listening to a radio scanner or a shortwave radio or some other things, and it lets me just pipe whatever into the headphones.

That’s $11 and looks like it’ll do 4 1/4 inch inputs. Looks like they also have RCA and 1/8 inch input versions (though those cost more, and there there might be more-inexpensive mixers).
That’s a great (and obvious) idea! Don’t know why I didn’t think of that… Thanks! :)
