Would something like this work to replace the SSD Card (though I guess it wouldn't be much of an upgrade due to its capacity)? http://www.newegg.com/Product/Product.as...

Could you PLEASE tell me the dimensions of this battery, as well as the one for the 17" model? I was thinking of modding my pre-unibody 15" to accept one of these batteries, but I need to know the proper dimensions first. Thank you!
