Unsolicited advice, but I’d do a quick check of what these older SKUs are going for. Here’s a similar listing for literally half that: https://community.frame.work/t/us-oh-framework-13-11th-gen-i5-1135g7/
Were it in stock, the 1135G7 board itself is only $199 https://frame.work/products/mainboard-11th-gen-intel-core?v=FRANFG000A
