USB Hub for a Mac Pro?

I am looking for the same thing for my MBA, and havn't found 1 yet. So you should let me know if you find 1, but i dont think it exists yet.

 

I'd personally go with a PCIe USB card. I can't stand hubs.

 

this one is made for mac mini, but it wouldnt look half bad sitting atop the mac pro..

this silver dome one doenst look that bad either..

edit: i would say this is still your best bet for looks:

 

I use that one - they are excellent. The base is very solid and stays put even with a full complement of devices hanging off it. It is also powered, which can be important for some USB devices.

 

I'll second the use of a USB card.

Previously I had a G5 2.3 Power mac and added a 4 port adaptec card to that.
I can't stand unplugging and shuffling cables around. In addition it is terrible to have a huge monstrous sized tower and then have to stack external USB hubs on top.
