I don't like it ... for a hosting site :p
No, serieus, it's nice, but it would suit more for a tutorial/funforum/.. site, something to do with an community.
- I dislike the top bar which has rounded corners when all the others have square ones, so maybe make them squared too
- The drop-shadow on the top bar is too heavy, lighten that up ;)
- I don't think that colour sheme fits right for a hosting theme, try flashy colours (warm colours)
- Add some server images to make the user give an instant feeling that he's on a hosting company site
Anyway, I didn't read all comments so sorry if these are said before...
Good luck with the design!
