... As a Steam Machine OEM.
The funny thing is, even though Sega dropped out of the console business years ago with the Dreamcast, they still went on to make arcade boards. Funnily enough they had hardware from all of their competitors except the PS2 (their GameCube based Tri-Force and the Xbox based Chihiro). Their latest arcade board, the Sega Nu, is for all intents and purposes a Windows PC. It has a Core i3-3220, 4GB of RAM, a GeForce GTX 650Ti, and runs Windows 8 Embedded. While that might not sound like a beefy computer, it's still enough to play most games at respectable detail and resolutions.
But in any case, I think they should package it up into a Steam Machine, with vouchers for several games they have on there. I'm sure it'd give the Sega fanboys a major hard-on.
