Corsair One Pro i182 - UK availability and possibility of custom options

Hi,

Looking to place an order for what is seemingly an amazing PC from an engineering standpoint?

When is the Corsair One Pro i182 going to be available in the UK?

Are there recorded DBL figures? Does it have silent mode like the i165?

If ordered direct, would it be possible to get one in a black case, rather than the titanium colour?

Thanks!
