[mythtv-users] Build for dual HD recordings - also is PSU enough/too much

[Digital Hit Entertainment]

Looking to build a MythTV combined frontend/backend to ditch the cable and go with OTA HDTV. Want to be able to duplicate our current cable PVR which enables recording two HD programs while watching another recorded one.

How's this line up? Realize it's not an HTPC case, but it's a small tower and a good price. 
Still need to find a good IR remote that works well with MythTV. Looking
 to buy in the next week or so.
 

I'm not 100% sure about whether the PSU is strong enough (or too much) so really need 
input there. (one day it'd be great if sales sites had enough info 
about components in their database to make PSU suggestions. :) )
