For sound, I am using my Sony Party Speaker system. I had it laying around and figured I can get more use out of it by using it with the PC.
This speaker system can connect via Bluetooth or wire to the PC. When not using my PC, I dock my iPhone or pair my HTC One via NFC. This has a great and powerful sound put out by its dual woofers and tweeters via 420 total watts of sound.
The build is almost complete.
