It's probably costing me more in electricity at the moment, I've got a
P4 2.8GHz with about 5 hard drives, the Athlon II Neo is a low power
system, runs at something like 30 watts. I was thinking of just going
for 2 drives mirrored, and probably the 'green' drives at that, it'll be
a saving on what I'm already running. I'd have to go for a GeForce 8400
or 210 as my TV doesn't have VGA input, only HDMI, so I'd need DVI out
and the HP Microserver just has VGA out.
It would also work out cheaper than running my PS3 as a media playback
device (and hopefully quieter too!). So basically I'd be replacing 2
boxes with 1.

If I was going to go for a client server system it would be for
convenience, the kids have a PC in their bedroom which they watch TV on,
they could use MythTV and record episodes of Tracy Beaker etc. :-)

I do like the look of those Revos, I may end up changing my mind and get
the Microserver and just use it as a server and then get a Revo
eventually. The Microserver attracted me as it was about £130 with

I tried MythTV on Fedora a couple of years ago, that was a bit of a
nightmare, didn't help that the Freeview tuner I had only picked up half
the channels, still does, just the other half after the digital

Sounds promising. Another factor I have to consider is I have an AV
decoder which has coax and optical digital in but no HDMI, and the TV
doesn't have any digital outputs. I'm currently trying to find a cheap
USB sound card with digital output that will handle streaming DTS and
Dolby Digital over either coax or optical connections. I've found one
that does it on Windows but it seems that it won't do it with Alsa.

Sounds good. We (well the wife and I) don't watch much telly, probably
a couple of hours a week but the kids do tend to watch a bit more than
us so maybe being able to record an entire series of shows might be
handy to stop the kids squabbling :-)

That's good. So I guess it's pretty much £1 per watt per year?
