Use different fonts for menu text etc. , without bevel and emboss.
Few "logical" mistakes on the top bar.
You took 1599px as width, thats good, planning ahead for bigger resolutions.
But why do you place stuff like "Server Status" and "Social Networks" so far on the sides?
That defeats the purpose of having the content area placed in the midle of the website since people on lower resolutions will need to scroll to the sides to be able to see the top bar statistics. So move them from the sides of the page to the center.
I don't really like the menu bar, I'd use a shape to define such an element and make it clearly visible.
But other than that it's surprisingly good^^
PS: change the background color. Let the background image fade out into it.
PPS: I wouldn't center the menu text. Keep it left or right. Center looks stupid.
