The Steam Store now has a hardware tab that contains listings for a range of Steam Machines.

The SteamOS-powered rigs run from US$480 all the way up to US$5000, and most sport a living room-friendly look.

Manufacturers from ASUS to Origin are represented.

The cheapest is from Alienware. It features an Intel Core i3 Dual-Core CPU, an Nvidia Geforce GTX 2GB GDDR5 GPU, 4GB of DDR3L 1600MHz RAM, and a 500GB hard drive.

At the other end of the scale is the Origin Omega, which boasts an Intel Core i7 4770k CPU, 3-way Nvidia Geforce GTX 980 GPU, 32GB of 1866Mhz RAM, and a 14TB hard drive.

All are expected to be available from November.
