<div dir="ltr">Hello Everyone,<br><br>I am quite new to Linux and MythTV but I have my box setup in the lounge alongside a humax. it has quite a nice config and it seems to be rocksolid as I continue to improve it's config...<br>

I take it this sets a wakeup time in the BIOS settings so the BIOS has to support this feature.<br>
<br>Talking about heat and that stuff... in this day and age I was considering using the vented heat from the cupboard to warm the house. in the summer I'll reverse the fans so it vents outside. Two benefits - one I get a warm house... two I get pre-heated fresh air in the house... during the winter... just need a dehumidifier for it and i'm done!<br>

I currently use hdparm -S120 so the hard drives turn off after 10<br>
minutes. I seem to get about 8W per drive when they spin down, however<br>
the / drive never seems to spin down. I guess it must be logging things<br>
or something.<br>
<br>
I currently use 2 drives for myth and 1 for file serving and another for<br>
backing up the pcs. These are spun down most of the time. I am thinking<br>
of converting all four to a RAID 5 array. I obviously get 25% less<br>
storage, but I assume that whenever any disc is being accessed all 4<br>
will be on.<br>
