Similarly, I went to add my MSI Wind, but the default model was not the same SKU as the one I have, but I noticed that further down they had a section for different configurations. I guess you just have to add them.

But I'm surprised by the complete lack of a Blu-Ray category. I haven't seen the "add a gadget" page yet (it's closed now because they got swamped), but I'd be surprised if there was a "new category" option in it.
