Usb Connectors Need to Split

[Emoney2007]

I have a D530 System Board but using it in a new case. Case has 4 Front Usb Connections. System Board only has connectors for 2 of them. How if possible can I connect the other 2?

Example:
2 [*][*][*][*]
1 [*][*][*][ ]

I really need this
4 [*][*][*][*]
3 [*][*][*][ ]
2 [*][*][*][*]
1 [*][*][*][ ]

Any way I can make that work from just 2 rows?
