Moreover, is an old iMac worth anything?
As of this writing (2011), on average I'd say most old Macs are worth about $100. Many less than that. An original 128k Mac, truly rare items and prototypes can command hundreds to thousands of dollars.
How many years should an iMac last?
Relatively speaking, hardware-wise, you should be able to get between 6-8 years of useful life out of a Mac. In my case, I pushed this to almost 10 years. That said, Apple tends to decide to obsolete Macs within a 4-5 year range by limiting what hardware will run their latest operating system.
