Where online can I find old computer parts (Monitors, cases, etc?...)

The cost of shipping obsolete items often exceeds their value. I think local is better.

Maybe just placing a Craigslist ad, something like “I will haul away your old computers and monitors for free!”?

@jaytkay: That’s certainly a good way of wording it.

Go to Freecyle register and post a WANTED:old computer parts Monitors, cases, etc.

I bet you get inundated with that stuff.

Try searching on google for things like “computer liquidators.” Or, contact companies that do ewaste or take computer donations.

You might also be able to just look online or in your local yellow pages to find computer repair shops in your area. They often take away your old stuff for you to get it recycled, but they might be willing to give you some of it, since they were just going to get rid of it anyway.

Are you building a robot or making an art piece? Sounds interesting.

eBay and/or Craigslist, although I think Craigslist would probably be more helpful.
If you were looking for Atari specific stuff I think there’s a place with a web presence that sells that, still.

Try yardsales, there always a yardsale with stuff like that.

It depends on where you are. Now, @jaytkay is right that people won’t bother shipping the stuff. I mean, the last computer I had shipped really did cost more to ship than it would’ve to replace. (There is a long story behind why I bothered, but I won’t bore you with it.) It’s one of those things that you either buy locally, drive to yourself, or do without.

Out here in the Seattle area, I can think of four actual stores that do nothing but old computer parts, and then there are organizations like Freegeek that make it a mission to recycle computers and parts. However, many (most?) areas are not nearly so lucky.

Thrift stores (Salvation Army, Goodwill, Deseret Industries…) may also have some stuff. But as far as online, Craigslist and Freecycle are about it.

Thanks!
