I'm thinking about building a HTPC, but don't know a great deal about them. I plan to have it under the Sky box by the TV. Could I record things from Sky (I guess some channels are encryped?) and or Freeview onto the HTPC? (Just need a low profile tv card?) What OS do people use? Do people still use XP MCE? Any free options? I've heard of XBMC but is that an OS? I have a bluray/dvd writer drive Im assuming you can play blurays and possibly burn recordings onto dvd's.
Oh is it also possible to stream live broadcasts to other computers on a network? (maybe need a fast wifi card?)
Any ideas on cases etc? I like the idea of a micro atx case using a regular power supply and a case that is wide and not too high, like silverstone ml03/ml04. Also saw one called xcase q4.
