BTW, House is fully LAN wired. Each room as 1 Network Port except for Study room where all the connections go to.
Upstairs, in MasterRoom, I have a 22in Acer widescreen 1680x1050 stuck to the wall (but the bracket custom made to enable me to move the Acer to and from the masteroom to the study to do other "linux" stuffs") This is connected to my Laptop and driven as an external monitor.
Audio is served via a 2.1 Philips speaker wired from the ceiling.
My system is nothing to shout about, but it just goes to show what a Linux Geek like me can do/perform using Free and Open Source Software.
Heck, I can even sell this system without needing to worry about licenses and stuffs.
Next project :
Getting My Long Range (DIY) Wifi link to work. Shoot to/from my sis in law's place (who has astro) if it works, then can consider getting a Haugepauge to record shows from there.

(using DD-WRT on LInksys WRT54G)
Okay lah.. enough selling.. (i got hot air in my head already.)
