Kasabian :
Or does it just have a few non-essential enhancements added? Is it really worth paying extra for the Deluxe version?
the deluxe has:
2 extra pci-e slots.
2 extra sata 6 gbps raid ports
a slightly better audio chip
built in wireless chip
2x extra usb 2.0 ports on the rear panel
2x extra usb 3.0 ports on the real panel
4x less usb 2.0 ports on the i/o panel
and some other minor things.
not worth it unless you need those non essential features...
