I like the case a lot, had my SAM in it for a bit. Think I paid about $85 for it on sale at Newegg.
PROS: size, real small. Looks are real, real cool. The open skeletal form of it is real neat visually. Lightweight (a little over 5 pounds), and top mounted fan keeps things real cool. Front IO panel connectors keep systems tidy and accessible, and the sliding mobo tray is nice.
CONS: the same open nature of it that I find to be nice eye candy also can make the thing a dust collector - your components are literally quite out in the open, so I'll probably never put any actively cooled mobo in this. Drive bays are somewhat limited, 1 5.25" and 4 2.5". Half height expansion slot and mitx mobo size requirements are a limiting factor to some. Price can be considered a little steep for such a small case.
They do also make a full ATX version of the Skeleton case. There are a lot more functional cases on the market, there's no doubt the primary goal of this one is visual impact.
