Use EGPU on MacBook Air?

I have a little question: For my birthday last year, my father gave me a MacBook Air in mid-2011, in top condition, because he handled it very well.

When he bought it 9 years ago it still cost him almost 3,000 euro, and I wouldn't like it if it wasn't possible to upgrade devices in this price range even after such a long time.

My question is specific: do you know a way how I can still operate an external monitor and an EGPU with the one Thunderbolt connection on my MacBook? If so, please send me the links to the adapter and the housing!

That would be super nice, because I can't find a case etc. That is compatible with Thunderbolt 1.

Here are my exact PC specs:

CPU: Intel Core i7-2677M CPU @ 1.80 GHz with Turbo Boost to 2.90 GHz

RAM: 4096 MB 1333 MHz DDR3

DirectX version: 12

Operating system: Windows 10 Pro (10.0, Build 19042 20H2)

Graphics card: Intel HD Graphics 3000

Total memory (graphics): 1664 MB

VRAM: 32 MB

my monitor: Full HD; 27 inches 59 Hz

Purpose: I noticed that I have a bottleneck with the CPU and the GPU in the PC; the CPU is perfect and super fast, but the GPU manages a maximum of 60 FPS in Minecraft Bedrock Edition (which I mainly want to play) (I know that my monitor only has 59 Hz anyway, but on servers or PvP battles, for example sometimes it goes below 30 FPS and that doesn't really have to be.) Thank you in advance!

P.S. (I would either install an RX 5700 XT or an RTX 3070 in the housing = D)

No chance, especially not with a 5700XT or 3070. Thunderbolt 1 is much too slow, and the CPU would be extremely limited.

Then you would also need third-party software (including PurgeWrangler), as Apple discontinued support for eGPU via Thunderbolt 1/2 with 10.13.4. But that doesn't always work very well

The device is also generally quite (age) weak. Investing anything is simply not worth it.

Hmm, I use Windows on my MacBook, can't you use an eGPU with it?

I'm not aware of any official solutions and I also doubt that you will get the eGPU to work under Windows even if there's something. You won't get any support from Apple for a 10 year old device, especially not for Windows.

On the internet you can find a lot on the topic and you can read up on it:

Maybe there's still a possibility, even if to be honest I wouldn't invest any more money there.

No, it doesn't make sense
