<div>I have a similar setup running on a 2.3 ghz Phenom x4 that serves as an HD frontend (using VDPAU on the on-board 8200 GPU), a backend w/2x PVR-500, a 2tb RAID 5 storage array (has my myth video files, music, and general storage) and it's generally running a Transmission client. In addition to casual web surfing, I've played Nexuiz (a first-person shooter game) @1080p on my 46" flat panel while the machine is also recording/commflagging and serving files to other frontends while also rebuilding the RAID 5 array (I added another drive, so rebuilding, redistributing...whatever you call it when you add another drive). I'll also rip several DVD's with handbrake simultaneously from several machines on my network (including the server itself), storing the output on the RAID array (which I would assume would be similar to running an HD-Homerun in terms of bandwidth), while it's recording, serving flies to other frontends, etc. My machine has 4GB of ram, the OS/Database has it's own hard disk, recordings are done on their own disk, and the 4 750 gb Raid 5 array is in the case too. It's connected to the same 16port gigabit switch as the rest of the machines on my network, which also helps. </div>
<div> </div>
<div>Granted, this backend only records SD, so the IO requirements aren't quite as high as they would be with HD recordings, you may not have a similar experience. </div>
<div> </div>
<div>I wouldn't say my machine is 100% rock solid stable (some people get a bit crazy about this if you ask me), but it's run for a month or more at a time without a reboot (and then only because I did a kernel update)</div>
<div> </div>
<div>So in other words, as long as your not fanatical about have 100% up time, and if a minor half-second skip in a recording or playback once in a great while isn't going to ruin you day, then I wouldn't hesitate to run the machine as you describe. If you expect it to be perfect every time, all the time, then I'd strongly recommend running a stand-alone backend server.</div>
