I don't believe that they'll even focus on users installing the OS, just like 99% of Windows users don't install their own OS. Valve will provide the reference SteamBox and encourage other manufacturers to release their own SteamOS-preinstalled boxes, giving users hardware options.

This is the end goal - but for the time being, it does seem aimed at tinkerers - the kind of people who already have a PC hooked up as an HTPC...

Keep in mind that this is the first of three announcements that they've, err, announced: http://store.steampowered.com/livingroom/

The second is in 48hrs, and almost definitely something related to the SteamBox. So it's too soon to speak of their intentions "for the time being".
