How about cost and risks do they count here?

The cost of a replacement logic board (P/N 661-02983) approx. $1,500 - 1,800 US! Thats very close to buying a used one.

The amount of work is quite high and there are risks if you are not skilled on opening this series of iMac's. Many people kill the display just in the process of opening the system. Here's the IFIXIT guide: [guide|57827|iMac Intel 21.5" EMC 2889 Logic Board Replacement]. Did you note the warnings! This is not something I would recommend for a DIY project.

Frankly, I would just make a backup of my system sell it and get a new or used system that met my needs.
