Re: kifaru xray
Should be OK. I carry a 15" (in the Keen carrier for that computer) and it's about perfect. The 17" is 3/8" wider on each side and 1 1/8" taller sitting on it side.
You might need to put a folio between the computer case and the back panel to put the computer closer to the widest part of the pack (this will also protect from shocks). The mesh compartment in the lid is perfect for the power brick, the top pocket carries a Wireless Mouse and other tech junk. Hope this makes sense. Heightwise you should be good.
I have the TAD FAST Pack Litespeed and it barely takes my 15"; yours would be a NO GO.
BTW if you post this question in "Tactical" you'll probably get more eyes on it and a better answer. The credentials required to participate there are civility and an interest in the product.
Hope this helps.
