The Steam Machine and Steam Frame are probably delayed, but they still intend to release them in the first half of this year.
They said they planned to have a concrete launch window and pricing by now, but hardware pricing/shortages have made that hard to pin down.
They did confirm two tiers for the Machine a 512gb and a 2tb. If they come out with a bare bones I’ve got a couple 500gb or 250gb drives lying around from old builds.
