Will this combination fit? I want to buy the Speck SeeThru hard shell case for my 15" unibody MacBook Pro and I was wondering if the MacBook Pro with the casing will fit into my incase sleeve? I'm going to college soon and I'm going to be taking the computer in and out and traveling from building to building with it quite a bit and wanted to make sure.... Also plan on purchasing the North Face Surge Backpack for complete protection.
