Pros
Pro There is a price range meter
Some companies do not have this but Material.net actually has a meter that allows you to set it at the range you want to spend for your Steam Machine. Keep in mind they are using the € so it will cost more here in the States.
Pro Simple design
It's not too distracting or in your face if you like simpler designs that still can contain some serious power.
Pro Upgradable
You can have your choices in various upgrades for the CPU, GPU, Storage, operating system, and memory.
Cons
Con Simple design
Even if it has a non distracting design, it still is pretty boring to look at and wouldn't fit well with your other consoles or even be something you'd really be proud to call your PC.
Con Not in the US
This particular Steam Machine can be bought from Material.net's site but they are located in France. You will have to deal with some hefty shipping fees to get it over here (if they even do international shipping).
