Everything USB published a review of the Belkin In-Desk 3" Grommet Hole USB Hub.

Quote from the review: "These days just about every accessory and peripheral you buy connects to your computer via USB. From printers and cameras to I/O devices and external storage devices, you can almost bet that you will need another USB port available to use it. Unfortunately many power users those with laptops have few available and have to resort to utilizing a USB hub to provide additional ports. Belkin's latest solution to this problem is the stylish and sleek In-Desk USB hub that slips into a grommet hole in your desk.
These hubs are available for 2" or 3" holes, available in black or silver, and they even have a model that is a dock for your iPod. Our model features 4 front angled ports, is silver, and fits a 3" hole."
