Anyone using the GMKtec mini PC as firewall?

Hi all, just looking to upgrade/downsize my HP Elite Desk 800 G2 to a GMKtec G9 Mini PC.

I've made sure to find one with Intel Dual nics to avoid any realtek issues with OPNsesne.

Will this serve as a worthwhile upgrade (lower power consumption, efficiency)

Has anyone has issues with GMtek or the G9 specific model?

EDIT: Bought a Topton N150 Mini PC

thanks in advance
