Just looked up the prices of that hardware...

mainboard €80
CPU 2.8Ghz €190
CPU 3.2Ghz €285
4x4GB DDR3 memmory kit > €600

Now thats some expensive memmory.

Because of de size restrictions Groove can prolly only handle motherboards with 4 Dims, and so you need to buy the very expensive 4GB DDR3 modules.

I don't know tough if Lionstracs supports people that want to upgrade the hardware of their systems.

A question to Dom :
Those 2 PCI PCB's, are those the interfaces to the soundhardware?
