I upgraded the memory in my 2009 Mac Mini. Now I have 2GB (2 x 1GB modules) left over with no use for it. PM me if you would like this memory. I think it fits a number of Apple machines, including other Mac Mini models.
Price: free to a good home (hopefully a regular AC participant). Shipping: $2 to CONUS (just mail it to me), or make a contribution to the charity of your choice and I'll throw in the shipping for free.
Thanks, -dB
