– The online Apple Store inadvertently posted the specs of the Power Mac G5 late Thursday. The system details came in the form of a .gif image that appeared on the store’s Power Mac G4 page. As of this posting, the image is still up. If (when) it gets pulled, you can view our screenshot here. Editor’s Note: Image removed at Apple’s request.

The specifications are as follows:

  • 1.6GHz, 1.8GHz or Dual 2GHz PowerPC G5 processors

  • Up to 1GHz processor bus

  • Up to 8GB of DDR SDRAM

  • Fast Serial ATA hard drives

  • AGP 8X Pro graphics options from NVIDIA or ATI

  • Three PCI or PCI-X expansion slots

  • Three USB 2.0 ports

  • One FireWire 800, two FireWire 400 ports

  • Bluetooth & AirPort Extreme ready

  • Optical and analog audio in and out

The new Power Mac is expected to be officially announced Monday at Steve Jobs’ keynote from Apple’s Worldwide Developers Conference in San Francisco.
