This silent water-cooled Thunderbolt 3 eGPU was $1500 new not too long ago. A good eGPU enclsure costs $200 minimum with poer supply and a water cooler cost $100, so the price is accurate. It's Thunderbolt 3 so you need to check if you have a Thunderbolt or USB 4 port on your laptop. If you are looking for a cheap Thunderbolt 4 laptop check out the i5-1135G7 laptops. I was using it with my Intel desktop and an RTX 3070 dGPU for machine learning butt I am getting three AMD Mi50 32GB cards.
