What this part of logic board is? (photo attached)
iFixit Community, thank you much for such detailed reviews and replacement guides! Really appreciate your work. I've got a pretty short question. I've bought an old one Mac Mini A1176 on Ebay and now I'm in the middle of cleaning and replacing the parts of this machine to boost it up and use like media server. I've replaced CPU, installed Crystal HD card instead of Airport Antenna, and upgraded RAM, but one part makes me really confused, cause I don't know what it is it, what does it do and what should I do with this part? (Highland on a picture, which attached with a link. It's by the right hand from RAM sockets).
Since my goal is to bring new life to this machine, what should I do with this thing? Cause it looks like CPU, cause it looks like covered with some kind of cooling radiator, but it's not made from steel. Should there be more doze of cooling paste or should I leave it like it was before me. Please, give me an advice. Thank you in advance.
Is this a good question?
