Backpack for 17 inch laptop - Axio

Guess I'm looking for a new backpack for my xps m1710, I've been looking at the dell gaming backpack made for the xps m1730, and the axio hybrid pack or their hardpacks. However I'm unsure if the axio packs would fit. I think on another forum some guy said it didnt. I'm leaning towards the axio packs but I just dont know if they'll fit.

 

I have the XPS Backback for my xps m1710, and it is absolutely huge. I don't usually care what people think, but it can be pretty embarrassing looking like I'm lugging around a friggin car on my back. However, it is build well (still looks brand new after 1.5 years), and being huge does have its advantages. I can pretty much fit my whole gaming setup into this thing (Laptop, mouse, keyboard, headphones, all cables... basically everything but my eternal monitor).

I've actually been thinking about picking up this bag for when I bring my laptop to school with me.

 

Are you about this one?

or the one made for the xps m1710, I'm only interested in the one made for the xps m1730 and the axio-bags.

 

I suggest Kensinton and High Sierra for laptop backpacks.
