Mac Mini and iMac Product Part Numbers? Available Tomorrow? [Updated]

Hardmac posts what it claims are the product numbers and rough descriptions of the iMac and Mac mini which are expected to be released tomorrow:

The new iMac models and their corresponding references:
- MB417: Entry level model
- MB418: "Mass market" model
- MB419: high-end model
- MB420: ultimate model
The entry level model should come with a 20" display, while the three other models will feature a 24" panel.

For the Mac mini, the references are the following:
- MB463: entry-level model
- MB464 high-end model

They cite a "reliable" source that has told them that both models will become available tomorrow. HardMac.com is the english counterpart to MacBidouille and is generally considered trustworthy.

Earlier today a photo of the Mac mini packaging was leaked and is increasingly looking to be legitimate.
