Christian, please -- and this isn't completely related with coin mining -- if you have direct contact with Nvidia and Maxwell chip has indeed an ARM CPU, tell them to add an USB interface (or supply a separate USB hub that links to the first few PCI-e pins) and allow standalone operation. No motherboard, no Intel/AMD CPUs, no 4gb system RAM, no Windows. Just plug the PSU PCI-e power pins and the card boots ARM Linux from a connect usb pendrive
I'd like to add a bit to this request. Could we also see a parallel port added to the video card. If i'm going to run Linux, I'm going to need to print.
Ethernet port would be logical as well, so I can connect to the internet.
Maybe a few sata ports, so I can connect storage harddrives too. If this is going to run an OS, it should allow me the ability to have decent storage, at a decent speed. Sata is way faster than usb, even usb3.
And lastly audio output. Both digital and analog.
