So I just got a Mac Pro 1,1 (2.66GHz) on Craigslist a few days ago. It came with 10GB of RAM, 1TB WD Caviar Black, Aiport/Bluetooth and 2 7300GTs. I paid $400 for everything, which I thought was a great deal. I ordered a bunch of parts for this, but I just have a few questions as I am not very familiar with Mac Pros. 1) I checked the RAM that was installed, there are 4x2GB from 'KomputerBay'...did I search and found them on Amazon. My main concern is temperature, the 2GB modules are running around 160-180F at idle, which seems way too high to me. The Northbridge is up there too, around 160F. I inspected the hot pairs and can see what looks to me to be thermal paste between the chips and heatsink? It looks like it was over applied, could that be the culprit? 2) As for the video cards. I recently bought an ATI 4870 from someone in the marketplace. Does this thing require 2 power adapters to operate, or will it work with just 1? 3) AirPort/Bluetooth reception...it's pretty terrible. The AirPort card I think is just a plain b/g, with no n. I tried the N enabler, but that didn't work...I was under the assumption that the original Mac Pro could be draft n enabled? Also, the Bluetooth reception is terrible...my mouse is lagging all over the place and the tower is less than 2 ft away. Any fix for this? I plan on adding 2 SSDs (1 30GB for Windows 7 and 1 120GB for OS X) both of which are OWCs, with a 1TB Black and 1TB Green...think I can still get some more years out of this thing?
