In my opinion, the hardware is overkill. I would focus on stability, not power because you will have to run the system 24/7. Also consider the cost of running a powerful machine for all that time. I have a trusty old VIA KT 400 motherboard running 4 tuners and a couple of PATA drives with an Athlon XP 2400 and 786 MB memory. It does the job and other things as well (Asterisk, IP masq, qmail, nagios, vncserver, snort, spamassassin, clamav, mysql, ntp, httpd, etc) but I only record in SD. It functions as a frontend as well hooked up to a Slingbox for offsite mythtv access. I have a trusty old 1Ghz PIII on an Abit VH6 2 ( with leaky capacitors ) doing a nice job for a frontend in the living room ( I have to let it sit at the grub screen for 5 minutes, presumably for voltages to stabilize before booting into linux, otherwise it just reboots 3 or 4 times before presenting mythfrontend); a Dell with a Celeron D in another and a Medion laptop for a mobile frontend wirelessly. Myth doesn't need all that firepower, I think unless you are recording HD.

<br>or RAID, which can increase reliability at the cost of more hardware and<br>increased complexity. RAID does typically require planning before<br>setting up any filesystems.<br><br>Jonathan Rogers<br>-----BEGIN PGP SIGNATURE-----
