Earlier today, a number of websites spilled the beans on Gateway's new "One" PC, which is widely expected to be announced tomorrow at the DigitalLife expo in NYC. Stepping directly into iMac territory, Gateway will unveil a sleek 19-inch all-in-one desktop computer that's just 3.6 inches deep.

The new "One" will be available in three configurations, two of them retail versions and one available only online. Starting at $1,300, the low-end retail version runs on a 1.5GHz Intel Core 2 Duo processor with 2GB of RAM and a 320GB hard drive along with Intel X3100 integrated graphics. The higher-end retail version runs on a 2GHz Core 2 Duo processor, adds an extra gig of RAM to 3GB, a 500GB hard drive, and Mobility Radeon HD 2600 dedicated graphics for $1,800. The online version will sell at $1,500 and will carry specs similar to the low-end version except for a 400GB hard drive and a Radeon HD 2600 graphics chipset.

Similar to the iMac, the One comes equipped with a 1.3-megapixel webcam and a slot-loading side mounted DVD burner. In addition, a wall mounting kit will also be available.
