We have an older iMac with "2.4 GHz / Intel Core 2 Duo with 4 GB of 800 MHz DDR2 SDRAM" -- that lately seems to be going south, with kernel panics almost daily. It always restarts itself, and then is back on track and OK. The shutdowns happen spontaneously, and sometimes even when the computer is not being used. But we are worried, and do not have much $$ to spend on a new computer. So my question, as noted in the subject: is it possible to buy a Mac-mini and utilize the display/screen from our existing iMac? Just bypassing the CPU/hard drive/ROM/etc on the iMac. I feel like this is probably a really stupid question, but we have no clue. The frugality of buying the Mac-mini kind of flies out the window, given that the only stand-alone displays Apple sells seem to be 27" and $$$.

It should be possible to connect a Mac mini to your iMac using Target Display Mode. See Apple knowledge Base article here. The spontaneous kernel panics may be due to the memory going south in which case, the cost of repair and replacement memory may be less then the cost of buying a new Mac mini. On the other hand, if you're willing to make the investment in a Mac mini, and using the old iMac as a display doesn't work out, you should be able to buy a screen (maybe even second hand) for less then $100.

Thanks for the info! Is there a way to test to see if the memory is failing? Also, where do you know where one can purchase screens for those prices?

You may want to run the built-in diagnostic test. See this knowledge base article for instructions.

As for finding a cheap monitor, watch newspaper adds for local vendors such as Fry's or BestBuy. Do searches on Amazon or check out Goodwill stores for a second-hand one. Monitors generally outlast computers and any VGA monitor can be hooked up to a Mac mini with a $10 DVI to VGA adapter.
