[clug] raspberry pi MythTV frontend or another option?

[Paul]

I'm looking for some options for second mythTV frontend for a spare room, as its going to 
be in-frequently used I don't want to spend a whole lot of $$ on a full-desktop and want 
to keep noise and power requirements low.

I'm wondering if anyone has any experience or actual setups which work successfully.
Note would need to be low powered  to reduce ongoing cost, otherwise I would need to put 
in standby or reboot when required as its not going to be used frequently.

I have send some projects using the Raspberry Pi, but also read its limited due CPU speed, 
but wondered if this is an option.
