Hardware Images
I made the desk from a Karri hardwood panel and prefabricated legs:
The eGPU bracket is made from an offcut of the desktop and some generic brackets:
The power-only USB port on the Aorus Gaming Box runs my monitor bias-lighting, which conveniently turns on and off with my system as shown in topmost picture.
Installation
Installation was very simple: Plug in Aorus Gaming Box power cord > Plug in Thunderbolt 3 Cable to laptop > wait until laptop has installed device drivers > install latest Nvidia graphics drivers > Done. EGPU works with hot plugging and cold plugging. USB peripherals are running perfectly under full gaming load.
The only other installation / performance alteration that I made is disabling the MX450 GPU and disabling / enabling the Iris XE GPU which removes any graphical stuttering and boosts performance consistency.
I also updated the firmware of the Aorus Gaming Box. This was a bit of a hassle, but I made a guide for updating older Thunderbolt devices with newer laptops here.

Comments
I absolutely love this ThinkPad and would highly recommend it to anyone. It is very well made, perferms exceptionally and offers outstanding value for money (AUD $1,289). The integrated MX450 is great to have on the go as it easily outperforms the Intel Iris XE. Furthermore, the RAM, two M.2 SSDs and WiFi Card are all user upgradeable. CPU performance is outstanding. I am particularly impressed with the Cinebench R23 benchmarks, consistently outperforming the reference 28Watt 1165G7 in a multi core workload by 20%.

Seems like a nice device ! Look at this Host to Device bandwith, 2480MiB/s is neat !
Do you have PL1/PL2 (W) and thermals (°C) values in perf mode ?
What CPU clock can be achieve in sustain loads ?

I am very happy with it so far.
PL1 is 35W and PL2 is 64W. Under initial boost it hits ~97C then drops back. I need to do more accurate testing, but it appears to be boosting between 3 to 4Ghz all-core while gaming, depending on the title.

Thanks for the info.
35w PL1 (sustain) for 1165g7 should be around 3.5-3.7GHz with 4 core loaded.
PL2 64W / PL1 35W is good and better than most of tigerlake laptops, hence the good CPU performance.
There's been some promising laptops lately with better PL1 limits with TB4. I'm holding out till June-July for the Tiger Lake H45 laptops to see if I can nab something with an i5-11400H that has a good PL1 limit. I'm really noticing 6c/12t is going to be the minimum of where I want to be if I'm keeping it for a couple-few years like I did with this current Gram 17. The new rumored Dell Inspirion 16 Plus with its 3K 16:10 display looks like it might be a winner, but I'm keeping my options open to see if anything with a good H45 CPU and no dGPU comes about. I've been tempted but I just can't pull the trigger on any of these 4c/8t units with H45 around the corner.
The i7-1165G7 is an excellent CPU when given enough power and thermal room. NoteBookCheck did an interesting comparison describing how the best performing 1165G7 nearly doubles the performance of the worst.
I am happy that Lenovo decided to push the E14 Gen 2 to its limit while only being an entry level ThinkPad model.

@boltoway do you know by chance if the 1.5mm heatsink for the other m2 is the maximum allowed height ?
I bought this laptop too 
("old" yoga 7 slim returned to the shop).
thank you.
@badea_cosmin_gabriel, I am not sure if it is the maximum allowed height, but it would be very close to it. I would highly advise using the same heatsink that I did for it, as it took the temperature of my SSD down by 30 degrees.
The 1.5mm option of this is the exact model I used.

Thank You for that great review!
Currently I am using a Lenovo T420 with an GDC Beast eGPU solution. I have ordered an E14 intel Gen 2 with an MX450 and it should be shipped around the beginning of january.
One reason to buy this laptop was the Tunderbolt Interface, because I am planning to use a eGPU there too.
--In this context, I have some questions regarding the MX450. (You said that You had to disable the MX450, because of issues.) :
-What kind of issues/problems did You had, when the MX450 was enabled?
-Did You disable the MX450 via UEFI (I dont now, if that is possible. Because at this point I do not own the E14) ore the devicemanager (ore some other way)?
Thank You and have a Merry Christmas
Marcel
Lenovo Thinkpad E14 + Sonnet Breakaway 550 + Nvida GTX 1080 (it works, but it is still a POC at this moment).
The only issue the MX450 caused is some stuttering in certain situations. This is very common with eGPU users who also have a dGPU.
In the case of the E14 Gen 2 you can disable the MX450 via device manager as is described in Windows 10 Solutions for eGPU BSOD, Crashing, System Freezing and Stuttering.
I would also do the Nvidia Power Management and TdrDelay fixes mentioned in the above post to your E14 Gen 2.
Excellent choice of laptop! If you have any problems getting it to work with an eGPU let me know.
