So I bought a powermac G4 a couple of years ago. It's the dual 800 quicksilver and I got it off ebay. Good deal at the time and the computer has never let me down. Weird thing is, in the bottom PCI slot has been these two connections that I've never known about. I got a good deal on a dual 2.7 powermac and need to sell this now and wondering what it's worth. So before I get that price, I'm gonna try to see if this will add to the value or not or even just find out what it is. On the actual card it has the word ATTO, which seems to be a company that makes several different PCI cards for macs. Here is an external picture of the card:
