I have a mid 2011, 27" Imac, 2.9 GHz processor, 8 GB RAM, 1 TB HD. The logic board is broken and it is not worth replacing, as the cost would be almost as much as a new machine. But, the hard drive is fine, and the monitor is in great condition. I am looking for advice on what I can do with the working parts of the machine. Sell them? (where?) Reuse them? (how?) Any advice greatly appreciated! Thanks!
