So, I'm going to build my first HTPC tomorrow, once the remaining parts arrive from Newegg, and I wanted to round up all the cool things people do with a decently well powered HTPC with a TV turner and cablecard attached. Please send cool ideas, functions or programs and I will update the OP to reflect them.
So far I have:
-Replace cable box and DVR and save enough money over time to pay for the system
-Stream live or recorded TV to multiple rooms
-Netflix and other streaming media services
-Light gaming (if no separate video card)
-Onlive for other gaming
-Home picture and video viewing
-Centralized storage and backup
-Blu-ray watching
-Wii, PS2, Gamecube, legacy system (other?) video game emulation
What else have you all used your HTPC for?
