Until we know the price point, it’s really hard to judge if the SteamCube is going to be a good entry point for Console > PC gaming, but I’m hopeful. Mostly because I don’t have time to build a PC and don’t wanna pay out the nose for pre-builts.
My local PC hardware store offers assembly and setup services for ~20€. Includes installing and updating the OS and drivers, as well as stress testing to verify that the components perform as expected. More places should offer that option, really. Especially if they also sell pre-built PCs that are assembled in-house.
