Gurus... I'm a bit bored of having to reach around the back of my iMac to plug USB devices in, so I'm looking for a nice 4 or 5 port USB hub to take care of duties. Ideally in white and also ideally one that doesn't need a seperate power supply if possible and also one with the USB ports at the front, as I've seen a few but the ports all seem to be at the back of the device. Anyway, what ya got!? Cheers.
