May I assume you got the meassurements wrong? I assume it would 10.7cm (width) x 10.7cm (Lenght) x 6cm (height)? and it seems the NVMes are at the bottom? I have the SZBox Slip 77 with also 3 NMVe but at the top with a big heavy metal cover to open toolless. very handy, but they are not available anymore :(.
Agreed in this case. Having a miniPC with an eGPU are just solving a problem that already has a solution (SFF PC). My take would be to either stick with a HX99G (or similar), or just build a SFF PC.
The AOOSTAR GEM10 is the latest mini PC offering from the Chinese brand. It has a reasonably compact form factor, with the chassis measuring just 0.6 liters. For its size, the tiny gaming computer packs powerful internals, featuring the AMD Ryzen 7 7840HS, 32 GB of LPDDR5 RAM, support for up to three NVMe drives, and an OCuLink port for connecting an external GPU.
