The design concept of the integrated Mini PC/eGPU slot was publicly developed and released by ITG Gear on February 2, 2025 (9 months prior to the product launch). Evidence is easily searchable on YouTube under the channel @itggear.
Chinese brand Topfeel has launched two eGPU docks, the G1 and G1 Pro. The main difference between the two is that the latter is an enclosed dock, while the former is open. Both have an affordable launch price in China and OCuLink connectivity.
