TL;DR: AOOSTAR's GODY mini PC offers a Ryzen 9 7940HX and RX 7600 XT GPU for $849, undercutting Valve's Steam Machine price, but it lacks RAM and storage, requiring users to add DDR5 memory and an SSD amid high DRAM prices. It runs Windows 11 and is larger than the Steam Machine.

Also no storage. So it's probably around the same price-to-benefit ratio of a steam machine: lacks the smaller footprint, tighter integration (including steam controller dock built in), no CEC (if you care about that); gains better upgradability, better gpu and cpu. Probably noisier as well, considering the higher tdp.

EDIT: Forgot to mention that 16 cores is pointless upgrade for pure gaming.

Instead of buying this, I'd just build a pc myself. This is the thing these steam machine killers are not getting: the gabe cube is not made for people who can build a pc on their own, it's made for the ones who want to have a pc-console that just works, no faffing about, no tinkering, no opening up and figuring out if the ram is seated properly or not. It's for those that want plug, sit and play.
