512MB won't get you far with hdtv. It won't even get you 5 minutes worth. Needless to say, you'd need at least a few GB of dedicated ram to even bother with it. At least ram is cheap now as you've pointed out (especially if you take advantage of MIR's). After seeing how much money I was wasting every month in my electric bill just by not setting a sleep timeout on my harddrives, ram is the only place I'd want any caching like that to take place if I were interested in buffering live tv.
Can you give tell us how much ? I roughly estimated the cost here in France : 1W on 24/7/365 costs 1€/year.
Leaving a green HD on 24/7 (Western Digital 1TB GP) costs me 5€/year here. Leaving the whole server on (4 HDD, DVB device, ADSL box, networking gear, etc.) costs me 65€/year... Much less than, say, hot water.
