Here ya go. I'm running both my mini and my gaming pc through this monitor. I've got the pc plugged into the dvi slot and the mini plugged onto the vga slot and I just push a button on the monitor to switch between the two.
I originally bought a 20 inch iMac. It was a really nice computer but I had just built my pc and it was a little difficult trying to figure out how I would use both computers. I was able to return the iMac, buy the base mini, 4gigs of ram, a 320gig 7200rpm hard drive, the Samsung monitor, wall mount, mouse and apple keyboard, and still have a little money left over. I use it for iTunes, iPhoto, internet, etc and its wonderful. Use the PC for gaming and internet.
