Alienware Steam Machine ASM100-4980BLK Desktop Console
There’s a lot to like about this system if you want a Steam Machine, but for general use you can probably find a better option elsewhere. This computer comes with an Intel i7 quad-core processor and 8GB of DDR3 RAM. You also get an NVIDIA GeForce GTX GPU with 2GB of GDDR5 memory, so it is definitely designed for gaming with the Steam OS. The 1TB hard drive gives you plenty of space for installing games and save files.
It also includes support for Wireless-AC and Bluetooth 4.0, perfect for downloading new games or connecting to wireless devices. No mouse or keyboard is included with this model, but it does come with the Steam gaming controller. Alienware doesn’t offer much in the way of upgrades on this system, but there are a few different models available with less processing power and memory if this is more machine than you need for your Steam gaming.
