How to add an internal drive to MS400H bis
A member of the French forum homecinema-fr, has also successfully added an internal drive but in this case he used a SATA connector used on a previous PC motherboard and he made a custom cradle for the internal disk. This proposal is pretty nice than Spanish solution unfortunately he had to solder a wired power connector directly to the PCB.
