So my question is, has anyone created a backend-only MythTV system using a small, power efficient computer, and if so, what components did you use, and how well does it run?<br><br></blockquote></div></blockquote><br>I'm quite happy with my Sempron LE1250 based backend. It has the following specs:<br>
<br>Asrock ALiveNF7G-FullHD R3.0 mainboard (based on power efficient nVidia 630a chipset)<br>AMD Sempron LE1250 CPU<br>1 GB DDR2 RAM<br>2 WD GP 1 TB hdds ("EADS" with 32MB cache)<br>2 Hauppauge Nova-S tuners<br>
<br>This backend runs CentOS 5 and cpupowerd throttles down the CPU and undervolts it when it's idling. When the processor power is needed it runs at stock voltage and speed again. Of the two harddisks (taking about 4W each during operation) one is powered down most of the time and is only mounted once at night to write backups to using rsnapshot aftwer which it gets unmounted again and powered down. Lastly during daytime I switch to 100Mbit and during the evenings it's back to Gbit ethernet. This saves another 2W.<br>
<br>When idle the system uses 37W. During recordings it can go up to 58W. The stability has been great. During the initial setup I had frequent lockups, but looking back the blame should be put on me for that :-). Once I figured out the erroneous MySQL entries that I manually added it has been rock solid since.<br>
