Not bad
Works well as a clean simple site, it'd be good to beef up that header a bit though, you need to attract people and its a little plain at present.
Those links top right are fine to be small but I would incorporate a small header (red) that hugs the top of the page and put these inside it.
Then you have all this wonderful space next to the logo
You could either fill that space with a nice image header or a headline in some nice large bold type?
Other than that reduce the logo in size and place it on the left next to the main site buttons and compress and shift these buttons to the right.
The rest of the layout works well for me
-Your header looks too empty right now in my opinion.
-Home/Login/etc looks out of place.
-Try adding seperators between your main menu items, making them buttoms to make things a little more interesting.
Otherwise looks nice! Exactly as you descrbed, clean and easy to read. Kudos :)
the same here about the header, it's to empty, clean style is good but this is to much :).
The charts again to plain, play with the charts a bit more, here is some inspiration:

You don't need to have contact in 3 different places, take it out from the top right navigation.
And you need a footer.
For the header I uploaded a photo, take a look.
Like the overall layout simplistic and clean and easy to look at not so hard to find thing. I don't like the logo though and I agree the header looks to empty. would like to se more interaction of the logo within the rest of the website.
