I bought a GT Snow Edition for a build about 3 years ago. It was exactly what I wanted at that time:
SATA backplane for drives
Higher end ventilation
USB 3.0 and water cooling ready
Something in white - very tired of a black or gray build
No problems at all with the case, as it does a great job cooling my components. One thing I did find out is the 200mm tri-color case fans are verrry hard to find in case one of the stock ones goes bad.
I initially wanted to buy a Corsair H100 mounted on the top of the case to cool my 2500k, but went with the H80 so that I could maintain the existing 200mm fan on the top, and the H80 then vents air out of the back.
I paid $275 for it new, which is an outrageous sum when I think about any past cases I bought. Before the Level 10 GT, I bought an Antec P180b for $109, and considered that all I ever wanted to pay for a case. After seeing the Level 10 GT Snow Ed., I changed my mind and decided I could use the case for any future build due to its size and layout.
