Hi, all--
Despite my username, I am a bit of newb when it comes to PPC macs. I recently bought a dual 867 Power Mac and have a few questions.
1. It came with a black power cable, which states it is a 300v cable. I'm pretty sure this wouldn't be the cable apple originally sent with the machine... I was expecting the original cable--which I believe is a 400v. Could this be the replacement cable that apple sent out to make the machine quieter 10 years ago? Should I not run the machine on 300v and wait to find a 400v?
2. Two of the expansions slots are open (image below) and it seems like it could be a dust problem. Are these open to keep the machine cooler? Should I close these off?
3. Is this machine a power glutton? I was thinking about keeping it running constantly, but the fan doesn't seem to ever go off. It is loud, super loud! I didn't know that it was nicknamed the "windtunnel" when I bought it-- now I know. Oh well, if I wanted the quietest machine available, I wouldn't be working with PPCs.
4. I am looking to buy a AirPort card with bluetooth. Is this possible, can anyone point me to the card I need (on ebay or elsewhere)?
Thanks for all of your help in advanced! This is my third PPC, and my first desktop PPC and I'm stoked to get it up and running.
