I recently received my new HP ENVY 17. I have a Vertical Brain Cell, however it is too small for my new laptop. As far as I can tell, Tom Bihn does not make a Vertical Brain Cell large enough for the HP ENVY 17. I want to purchase something similar to a Vertical Brain Cell (preferably not the Horizontal Brain Cell) that will fit into my Brain Bag and be large enough to fit my HP ENVY 17. Any suggestions?

The dimensions from HP's website are:

16.38"(W)x10.83"(D)x1.25"(min height)/1.52" (max height)
