I made the desk from a Merbau hardwood panel and prefabricated steel legs:
The eGPU mount is made from some generic hardware brackets and my ThinkPad Dock is mounted with double sided tape:
Installation was very simple: Plug in the Wikingoo eGPU with it already powered on and wait until Windows has installed device drivers > install latest Nvidia graphics drivers > Done.
It can be hot plugged, cold plugged, will display the Windows login screen, support Windows sleep-states and can even display my system BIOS from either a cold startup or system restart. The later of these was something that my Aorus Gaming Box 1080 could not do. Furthermore, it works exceptionally well while being daisy-chained through a Thunderbolt 4 dock.
I added a TdrDelay ValueData of 10 and a TdrDdiDelay ValueData of 20 in the Windows Registry Editor to allow Windows a longer 'timeout' period for the GPU to respond. It has fixed many crashes and BSOD errors in previous builds , with no downside whatsoever.
I changed the Nvidia Power Management Mode to 'Prefer Maximum Performance'.
I further modified the Windows Registry to add Link State Power Management into my Windows Power Settings.

One of the most interesting features this laptop has is a BIOS Level Discrete GPU Switch. This disables the NVIDIA MX450 at BIOS Level and is no longer visible to the OS at all. This is extremely useful for an eGPU System where driver conflicts or performance / stability issues occur when a discrete GPU is present. This is an issue I had with my E14, having to disable and then re-enable the MX450 upon a system start. This is no longer the case, and absolutely no software changes need to be made once the dGPU is disabled in BIOS.
Another feature that I appreciate is BIOS level Performance Profiles. Under Intelligent Cooling, the laptop runs very quietly and performs almost identically to my i7-1165G7 E14 System in Cinebench. With the Extreme Performance Mode enabled there is considerably more fan noise, but the CPU now outperforms the i7-1165G7 in both Single and Multicore Cinebench R23.
The cooling system for this ultrabook is excellent. It is extremely quiet under the Intelligent Cooling mode and keeps CPU temperatures very well controlled.
That laptop looks really ideal.. great looking setup!
I assume you stay away from Resurgence playlists? That map causes massive frame rate dips when you look at the center of the map.
hank you! It is by far the best Thunderbolt 3 laptop I have ever used with an eGPU. Since I started using the Wikingoo, I don't even have to disable the MX450 in my system. I get no stuttering or performance loss leaving it active all the time. Incredible!
I tend to stay away from that entire game haha. While this is the best performing TB3 eGPU system I have tested in Warzone, there are still moments where the performance is incomprehensibly bad. You are correct with Resurgence being an example of this.
