"Work laptop" with external GPU via Thunderbolt?

[TukangUsapEmenq]

Seeing this video kind-of inspired me of posting about this.

 

In a nutshell, I want to get a secondhand ThinkPad (either T480/T480s/L380/T490/etc) simply because I need more performance when I'm working outside of my living place (current laptop is a smol ThinkPad 11e with M-5Y10c + 4GB RAM). And, as of other ThinkPads, they mostly have Thunderbolt 3, and I sort-of want to utilize this by using the external GPU, in which I'll retire my PC (and taking both the PSU + GPU + storages only), specs as below on my signature, because I actually live on boarding houses for work, far from home, and with nearly 2 years of having a PC kind-of hassles me of carrying PC case everywhere I move. And... By my little research, my PC with E3-1225 v2 actually lose a little bit in performance with the i5-8250U. Dang, how technology evolves.

 

Yes, I am well aware of the bottleneck of using this kind-of implementation. I know my GTX 1650 wouldn't fully perform on this setup, but it'll run on 1080p or even external 1366x768 60Hz monitor anyway, and tbh I don't game by that much (maybe some Asetto Corza/Dota 2) nowadays. What I need basically is portability for now, and simplicity of plug one USB-C (which will charge and connect to my monitor + mouse + keyboard + perhaps Gigabit ethernet) and I'll get my battle station ready. And I plan to make custom enclosure just for the sake of not 'hanging the GPU + PSU way too open'.

 

But... I just want to know on how your experience of using this kind of setup. Please enlighten me about this, like does this setup will worth the effort?

 

Thanks in advance.
