I had an entertainment setup and of late I have bought some more gadgets to make it better. The below snapshot has the overview of how it has been wired up.
Currently I have a 22 inch HD TV
5.1 Speakers with DVD player
Two notebooks Alienware M11x and Dell XPS M1210
Two Android phones Galaxy 3 and Xperia Neo V
A Samsung Tablet
Seagate Goflex Home NAS, connected to wifi router over LAN and WD My Book Essentials 1 TB plugged into the USB port of the NAS dock.
The speakers are connected to the PS3 via optical cable for Dolby 5.1 and to the TV for 2 channel Aux input.
The PS3 is connected to the TV via HDMI and TV set top box is connected to the video in on the TV.
The NAS can natively download torrents and also runs a media server. The torrents can be controlled remotely via a SSH tunnel between my Android phone and the NAS. This feature is still buggy and I would need to get a new router to get this fixed.
My XPS runs PS3 media server and can stream all the content on the XPS. That makes two media server in total.
When needed I plug in my M11x to the TV and play the games on the TV via a wireless Keyboard and mouse.
This has been my setup, I might have missed out on some details, do let me know what do you think about this.
