Okay. I have custom built what I hope to be my LinuxMCE core and media directors. I have four motherboards mounted in a case, with four power supplies, four power switches, fans and 6TB of storage. Each motherboard can be turned on or off independently. The bottom motherboard in my stack is the core. Based on a Tyan S3115GM2N motherboard (no nvidia graphics, but dual nic, and an atom server board) it has a 64GB flash drive connected for the system files and three 1TB hard drives in a backplane arrangement for storage. The other three motherboards, for media directors, are Asus AT3N7A-I's. The next motherboard up from the Tyan board has another three 1TB hard drives connected via SATA backplane. This motherboard is for the media director in the lounge. The other two motherboards have no attached storage. I have on order four DVB-S2 C 2104D usb tuners on order for my satellite feeds which I hope to connect to the core and to the lounge media director (two to each). The intention is to leave the core and the lounge media director on at all times, and turn on the others as required (one will feed to my dining room, and the other will provide a central audio source and/or act as a media director for the kitchen). All of the places that screens wiil be located are within a 5m cable run of the rack installation. Currently none are connected via HDMI, rather they are all connected to an old KVM switch in the rack via VGA and ps/2 to usb converters.
Ultimately I will connect a cd/dvd drive via usb to the lounge media director. I also hope to connect usb soundcards in various configurations (I have ten lying around and like the idea of moving the soundcard away from electrical noise from the server rack). As a result I'm trying to use a bootable usb drive to install Linuxmce.
Switching only the core on and booting (successfully) from usb flash drive (using the snapshot published on the 8th of this month) I get the following. It asks for my language and then reaches the install menu. I select install kubuntu. The sliding blue bar indicating progress runs for a few minutes, and then freezes. No progress.
