Installation steps

-I made custom power cable for the grahpics card first. Basically soldering two 8-pin PCIe cables to 6-pin PCIe cqble (all male connectors) So I can use dock's power output connector
-Set the ExpressCard link speed to gen2 in laptop's BIOS
-Connected eGPU to the laptop, installed drivers which resulted in Error 12.
-did DSDT override using Intel method and DIY Setup v 1.35
-Limited eGPU's Power Limit to 85%. GPU Still boosts to full clocks but does not cause power supply to cut out (probably due to over current protection tripping)

Comments (eg: how has the eGPU improved your workflow or gaming)

At first I thought getting the DSDT override to work is going to be quite hard, espexcially as I saw 43 errors pop up when compiling the modified .aml file. Errors were an easy fix though as I followed nando4's quide. Adding eGPU to my laptop allows the CPU to stretch its legs as iGPU was severly limiting it. I will be using this setup when I will be at my apartament (Long story short, its too awkward to bring my pc over there and back home every week)
