Cases for Macbook Pro Retina

Hey guys,

I have a 2012 Macbook Pro 15 inch non-retina. I was wondering if cases designed for macbook pro 15 inch retina would fit my macbook pro 15 inch non retina. There are a couple sleeves (not hard shells) on amazon that caught my eye and are affordable. Would those work for my macbook? As in would they fit?

Here is the case:

Thanks.
