What you'd want is a NUC with AMD. With an iGPU of 780M or higher, you'd equal or beat a Legion Go. You'll find plenty of NUCs like this from Beelink, Minisforum, etc. Usually at $400-800. Depending on sales.
Intel's Lunar Lake is another option. The iGPU on that line will match or exceed a Legion Go too. Right now, it's mostly in laptops but some NUC models have been announced.
