Looking for a motherboard with HDMI output (with sound over HDMI) that supports Linux VDPAU for full-speed 1080p playback. Before you all shout "Ion!," this isn't for a quiet, set-top box, but for a whole-house server in a full-sized, tower case with a current count of 2 ATA and 4 SATA mdadm-RAID (not hardware RAID) hard drives.
My mighty "Traseron" is aging, and I'm gutting my entire home entertainment system, doing structured wiring, whole house high-def, and starting from a clean slate.
"Traseron" is currently my central hub. It's my MythTV backend, file server, torrent downloader, remote access hub to the house (I'm on the road a lot), rsync backups, and serves three original Xboxes throughout the house for all television, movie, photo, and music needs. It lives in a closet with an old CRT monitor for those few times that a remote X session remote shell won't do.
I'm ditching MythTV (used only for television), but still need its massive two terabyte storage space (or more, since I'm stepping up to HD). I'm moving it to the future equipment hub, which is in line of sight with an HDTV. As such, I first considered just throwing in any HDMI video card so that I could do local management via the line-of-sight TV when necessary. Then it occurred to me, I could actually include it as a player in the whole house setup, with a modern motherboard and graphics set. This would complement the Mac Mini that I'm adding for the express purpose of playing videos served from Traseron. (Heck, if there were a Linux solution to iPhoto playback, I'd not even bother adding the Mac Mini as a middle-man.)
The little Zotac Mag that I've been playing with as a substitute for my original XBMC-Xboxes in the current system has blown me away, especially with its full-speed playback of 1080p h.264 files. But it's not a file server, and a quick search of Newegg motherboards that have HDMI has made me realize that I've not kept up with things since I built my current server. Do all of this little "Micro ATX" and "Mini ITX" fit in a standard, full-sized case (including the exposed ports in back)?
Hope my thoughts are clear. Thanks for any suggestions!
