    I've been considering getting a new Mac mini and finally retiring my eight year old Power Mac 2.0 GHz G5 dualie. About time huh? :rolleyes:

    I'm not 100% set on the mini, I'm also considering an i5 iMac - either a 21.5" or a 27".

    Does the 21.5" run warmer than the 27"? I assume its internals are the same as the 27" but more tightly configured.

    Just wondering.

    I'm curious as to why it even matters. They will both heat up under load, as any all-in-one computer tends to do.

    The imac 21.5" have less power hungry CPU, graphic card and a smaller screen, all produce less heat than a 27”. So I’m not sure how much that factor in the overall temperature inside the case.

    It's a computer, let it get hot. It isn't going to break before it shuts itself down.

    My iMac (i5 2.7 27") gets plenty warm under load and I'm fine with that. I don't feel the heat in any way, either. (CPU is 62 degrees Celsius atm)
