The laptop itself is based around a CLEVO machine, which I believe are used by a number of different DAW workstation providers.
The top-end Clevo shells are heads and shoulders above the average "off-the-shelf" laptop.
The price reflects this...
Where you get into issues with typical off-the-shelf units is when trying to run substantial loads below a 256-sample ASIO buffer size. Just because a system's DPC latency is "in the green" does not mean it's capable of this. "In the green" can be up to 500uSec... which is actually pretty poor performance.
ie: A well configured SandyBridge-E/IvyBridge tower will have DPC latency that idles below 10uSec... with peaks ~24-28uSec. You won't find that in *any* off-the-shelf laptop.
The smaller the ASIO buffer size you intend to (effectively) use, the more critical DPC latency becomes.
A typical off-the-shelf laptop is made for the general-purpose user.
This user is much more concerned with long battery life than achieving the utmost in performance.
It doesn't take a screaming machine to surf the Net, run MS Word/Excell, get on Facebook, and do light photo editing.
The power-management features in laptops is what causes higher DPC latency.
In most off-the-shelf units, there's little you can do to rein-in higher DPC latency.
BIOS parameters are often hidden (not exposed) to simplify the machine... so a novice user doesn't foul it up.
Another thing to keep in mind:
An i7 CPU has four cores vs. the i5 which has two.
BUT... look at the clock speed of both CPUs.
A fast clocked i5 can outperform a slow clocked i7.
Unless you absolutely need the portability of a laptop (travel often via plane), I'd recommend a Cube.
All the speed of a full tower... with none of the limitations of a laptop.
You can get a small rolling padded case that holds the Cube, small monitor, and mini wireless keyboard.
A little more cartage than a laptop... but a whole lot more firepower.
