For those who know, notebooks Asus RoG are built as panzer, with a heavy frame, strong and bulky. The huge ventilation system gives them a larger than regular laptops. Most bags designed for computers 17 "-17.3" can not accommodate them.
One note to specify:
The laptop take * any * room in the main compartment. You must remove the separator (held by Velcro strips), and use the front pocket for charger and accessories. You can not store next to the laptop as on the pictures if you also have a monster like that.
Another consideration:
If traveling by plane, the dimensions of this bag (and by extension the monstrous laptop is inside) exceed the sizes allowed for "personal items" other than cabin luggage (bag, portable, aid kit, door -Documents) on most airlines. You may need to consider storing your laptop in your cabin baggage, or take this bag AS cabin baggage.
