OK so My main computer is an I7 macbook pro. Im quite used to its speed and power. But am looking for a desktop just to have as a second computer. I was looking at used imacs like a 24" or something. But them stumbled on this powermac. It has duel water cooled 2.7 G5 processors, 8 gigs of ram. two 750 gig hd's and an ATI Radeon X800 XT with 256MB VRAM graphics card. Never had a G5 mac before. All my macs past and present have been intel. Is it a good computer or should I keep looking at an aluminum 24" imac?
