[mythtv-users] Mini-ITX or standard PC?

[Piers Kittel]

Am planning my MythTV box in which I'll be mainly using as a PVR, 
currently recording analogue TV, but in the future might use digital TV, 
DVD player, and a few other minor tasks - but I'm trying to find a 
balance between power and noise/electricity usage.  I would like to aim 
for a low electricity power and low noise, and cost isn't the greatest 
concern here.

Would a mini-itx mobo something like M10000 or the MII12000 be 
sufficient to use as a MythTV box or is it overkill?  Or would it be 
better to go for an MicroATX board with an underclocked AMD XP/Sempron 
processor with a big heatsink and a slow fan?

Or would more details would be helpful here?

Thanks very much for your help in advance
