What's that sound equipment there? Why so much? Explain what each does?
A lot of it is very old legacy equipment from the late 90's. It was high-end then now, and still works just fine for the speakers it drives. There's a tape deck, amplifier, CD changer, and mixer in the picture. The tape deck sees no use and the CD changer little, haha.
Could you share more pictures of the projector in use?
Not bad for a $1,500 projector @_@
Why so much hd space? Also, why the clock?
The computer is also a server for movies and backups of other devices in the house. That storage is all network-mountable. The clock is just for fun, and because who didn't love Netscape?
