The only negatives of the SVC version and the standard ver. 2.0 with the tailed springloaded version is the ugly decals and the inability to attach more than 1 fan per channel w/out splicing to a 3 pin connector.
Also, I'm not sure if the SVC version allows you to totally turn the fan off, as the standard ver. 2.0 one allows (with a click). I'm not sure if the silver one matches identically, but the black one isn't the same brushed aluminum finish, its more a glossy alumuninum finish. Still looks great though, and yes, the LEDs are VERY bright
I got mine at Xoxide, just make sure you specificy color, as I wanted a silver one (as pictured) but got a black one. Turned out alright though, as I dyed my drives black to match. Looks quite good and adds some character to the front of my case.
