Valve could also just partner with Dell. We're already starting to see Dell experiment with something like the Alienware X51 for a gaming centric PC. Have one or two very rigid hardware targets and let the Dells, HPs, and Lenovos build the machines. Games will be tailored for these machines above other configurations. Something like Nvidia's Tegra Zone. The OS will need to be clean, no antivirus, no background tasks. One of the big hurdles that PC gaming never jumped over is the pick up and play nature of consoles. It just has to work, and work with a controller except for RTS type games. No funny error messages, .Net installs, etc when first loading the game. Reducing hardware permutations and having strict OS controls is the only way this can happen. In fact it is MS more than Valve, if they wanted to, who are best equipped to do this type of thing.
In which case you just end up competing with Dell with a more expensive piece of hardware offering the same level of performance. Besides as you noted Dell already has that (Alienware). And HP has VoodooPC. The market for those machines is fairly small due to the high price premium and why you don't see many boutique gaming PC OEMs anymore.
With an open PC box, I'm not sure what Valve can really do to distinguish themselves other than just their name on the box. They'll get a bit of internet cachet and notoriety for it being a linux box, but I don't think that'll be enough to propel it into being something profitable.
We'll see how it goes. But while it's certainly a more solid foundation than the many previous linux gaming box attempts, I'm not sure it's going to be that much more successful.
As before I think it'll come down to pricing and whether they can get some compelling linux Steam exclusive games. If the price is too high that'll end up only being attractive to enthusiasts. But enthusiasts will likely prefer to build their own box. The price will have to be quite a bit lower, IMO, to attract people to a non-windows box.
