The iPad 3 may be the most talked about and leaked product in Apple’s history. With the device launching on March 7, the amount of leaks are only going to increase. The latest leak gives us a look at its external components to get an idea of its dimensions.

M.I.C. Gadget secured through its various sources some of the external components that will be making up the iPad 3, or iPad HD. The biggest surprise is that the case of the iPad 3 is about the same size of the iPad 2, with the iPad 3 being a bit thicker.

The components that M.I.C. Gadget were able to obtain confirm some more of the device’s capabilities and features. The first is that the iPad 3 will retain the home button that all mobile Apple products are known for. You didn’t think Apple would make a buttonless iPad, did you?

The second is that they have confirmed the memory configurations the iPad 3 will come in. There will be 16GB, 32GB and 64GB models available just like the iPad 2.

Sources say that there have been thousands of iPad 3 cases shipped to the US over the last few weeks. Fret not though, iPad 2 cases barely fit the iPad 3’s increased thickness, but still fit nonetheless. For those who use the smart cover accessory, you’ll find that it still fits just fine over the iPad 3’s display.

Check out the video below that looks at the external components of the iPad 3. It should hold you off until the official unveil on March 7.
