#7 The icon placement should be off to the side for something as big as this one. Also, it might be better to shrink the size of the icon a bit? Same for
#4,
#5 and
#6 as well.
I like the font used in
#4 and
#5 a lot. The spacing is good, and I like the way it's laid out.
#9 and
#8 I like this icon a whole lot. The colors are good, it's simple and hints to being servers, without screaming "OMG THESE ARE SERVERS". =)
