[W] DDR5 SO-DIMM 16/32 GB and 7940HS, 8945HS "780M" or "890M" Mini PC/ITX

16GB (2x8) for $100?

32GB (2x16) for $200?

MiniPC with these 7840HS, 7940HS, and 8945HS typically go for $200-270 on ebay depending on features.

The key is the 780M GPU. Some variants like the 7945HS comes with the lessor 610M - so I am not interested in those.

There's also the AMD AI 9 HX 370 which comes with the upgraded 890M I'd be interested in as well for a bit more. The N5 Pro looks good, but is just out of our budget though.

The goal is to build a retro PS3/PS2 TV gaming station for the kids for their birthday.
