This laptop is based on the Clevo P750DM2-G, I think. This model can be configured, but I find the most interesting configuration to be a GTX 1070 + I5-7600K or I7-6700K. The 7700K is another cost which I'm not sure worth it.
The coupon gives 10% off + unlocked bios + delidded CPU + 120HZ display
The P750DM2-G has many connection and storage options, with two M.2 NVMe slots, mini DP 1.3, HDMI 2.0, Thunderbolt 3 and more.
The most basic GTX 1070 + I7 configuration includes 1TB 7200RPM HDD, I7-6700K and GTX 1070 + 120HZ display if you want it (but that's a mediocre TN panel) and it will total at $1585. The I7-7700K version will cost ~$1675. The I5-7600K configuration will cost $1416 which is quite low for such a laptop.
This model has a replaceable MXM GPU and ofcourse a socketed CPU (but 8th generation CPUs will not be able to work with this chipset)
The Delidded CPU will probably result in much lower temps and has an advantage over other laptops
