Need some storage help

[Vrokar]

Short Version, ive had a 17 inch laptop backpack for years. Still in excellent condition... but my new 750J doesnt fit in it. Not in the laptop portion anyways. So I decided buying a sleeve and putting it in the main pouch would work. But I cant seem to find any sleeves that fit the G750J.

Anyone know of any that do? The cooling seems to extend the back enough that none fit!
Thanks in advance!
