This unit has a small footprint with a computer casing made up of what they call "FyberFlex," which is supposed to be really strong. As you can see from the youtube video it is very flexible. Im not sure why you would need for the structure to be flexible unless you are traveling with it. The more expensive option has a liquid cooling system which always has the risk of leaking and destroying your system.The graphics options includes configuring it with a GT 610 or the GTX TITAN, the fastest graphics processor for gaming or film editing.
e3io.com says that this has "extreme performance" but you can only configure the more "affordable" SK01 unit to have Sandy Bridge Processors which Intel will be discontinuing very soon. The SK02 has the Ivy Bridge processor but Intel's current processor is the Haswell processor which tend to get very hott when overclocked for gaming. The best option they have for non-liquid cooling is the COOLERMASTER Hyper 212 EVO which is not as efficient as the products from Noctua. e3io.com has some other desktop and gaming configurations but they all include liquid cooling which can be risky if a leakage occurs.
