Looking for an mITX GPU and MacBook Air

I am looking for an mITX compatible GPU, ideally it should be MSI RTX 3060 Aero ITX, but all other compatible options are potentially interesting as well.

The requirements:
- Max 16cm in length with power connector at the rear.
- Max 17cm in length with power connector at the top.
- At least GTX 1660 Super / GTX 1660 Ti performance.
- Max two slots in width, not 2.5 like Asus RTX 3060 Phoenix.

The price is negotiable, but max 3000 SEK. I also have an R9 Nano that I can offer as a partial payment. I could imagine paying more if the purchase receipt with warranty is available.

-----------

Also I am looking for a cheap MacBook Air (or Pro) to donate to a refugee engineer that has lost his entire business due to ruzzian invasion.

The requirements:
- Intel CPU (not Apple silicone).
- DDR4 not DDR3 RAM.
- No damages on the screen.
- Not expensive.

That's a bit too much for a GTX 1660 Super, but how old is it and does it come with the purchase receipt?

>also have a HP OEM 2060 Super 8GB with rear connector, 3k including shipping

This one is unfortunately too long, it's ~18.5cm, the limit is 17cm.

Update: I have already found an ITX GPU (waiting for shipment).
