Diddo what the previous two have suggested. The bg is way too dark. Text needs to be a shade or two lighter. The brown naviagtion sticks out in a not-so-good way. The services page is cramped, maybe place content in a scrolling div. The area beneath the Navigation box needs someting there.
I do like the design/concept. IMHO it just needs a few tweaks. It would be cool if you added some "flashiness" to the KF Computers box in the upper lefthand corner. Maybe animate the marble bg or have a highlight go through the text. Just some ideas...
Nice job!
