If you need to buy right now, and don't have time to bid, then yes, prices from the recycles are steep.

But there are lots of cheaper options if you have time, don't mind buying from foreign countries and like a bit of risk.

No such thing as a normal price. Could be free for many of us, because people know "we collect old computers".

But also in general, you are quite late, many of us have been doing this for many years, so we have seen many bargains come along 😀

I do have a lot of old computer parts. I just have not been collecting them for long. They are just parts from computers I had 20-30 years ago. Another thing is that if I were to sell something on ebay, should I just follow the prices I see for similar components or would that result as nobody buying it? I suppose main thing I lack is experience of knowing when I see a bargain and when something is overpriced. That is something I would like to learn from those people who have been doing this longer.

Hi, sorry, I don't know if people really buy them (btw, ever tried to get an original AdLib card ? They often go for $200 to ~$400; and sometimes that's just for the bare card!).
But I do know that prices went high in the last five years or so.
Once (sowhen in the 2000s) there was a time when such systems could be found for free on the road side.
Though that time is long gone by now. I'm afraid most of them went the way of recycling already.
Now, Pentium III or Athlon systems took the place of these systems (in terms of price and availability).
If you're lucky, you'll also find 386 mainboards *cheaply* for about 50€.

> Do people really pay $150-$200 from these

On Ebay you can filter for actual sold items.
