Well only I can say that Ps3 can take much more hot air than MacMini.
I found another mac and today I will put my hd in that one.
Do I must reinstall my mac system again? I think that MorphOs will work, only new key is needed for normal use.

Now I have only blank screen, I can send only old images of trashed screen for new key.
Will this be enough for transfer of key? Thanks again.
