I've done some reading on Mac Mini and Apple TV, but I haven't seen this particular setup that I have imagined. Here's what I'd like to do, if it's technically feasible. Hardware: Mac Mini 2.26 GHZ. Upgrade RAM to 4GB, upgrade HDD to 5400 500GB. Mac Mini hooked up to my 65" HDTV downstairs, with adapter to HDMI input. Hoping to hook up a nice set of Bose computer speakers, so I can get rid of my combo DVD changer / receiver / 5.1 speaker set. I like it, but trying to really reduce the number of boxes under my TV. The ability to control *everything* on the Mini from the Apple Remote. As far as I can tell, Plex seems to be the place to be. Though I'm not clear on if it can read movies from iTunes? Most of my movies are in iTunes, and I don't want to have 2 copies of my movie collection. OK So that's downstairs. Trying to keep it extremely simple. I know that I'll lose sound quality by not using a digital audio out to my 5.1 set - and I'm OK with that. Surely the bose computer speakers will do fine, though. I'm no audiophile. Simplicity is extremely important, and I don't want to have a keyboard and mouse in my living room. My wife and son need to be able to work this setup with ease, so I'm hoping that the apple remote can do it all. Maybe wishful thinking. OK Upstairs, I'm thinking just an Apple TV. I know I won't be able to play rented DVD's, but that's not a huge problem, as I watch them downstairs. I'd like to stream my movies from the Mac Mini downstairs, since the ATV hard drive is so tiny. Possibly I'd like to be able to watch Hulu and Netflix from the ATV, but that's not a big deal. Main Questions: Can I stream videos from mac mini to ATV WHILE someone else is watching movies downstairs on the mac mini? Or will that make the little guy explode? And, of course, am I missing anything? Expected cost: Mac Mini $600 4GB RAM: $120 500GB HD: $90 Bose speaker: $400 ATV: $229 Total: $1439 , not including the few cables I would need. That's a lot of cheddar really... though it would probably allow me to cancel cable. I can get much of what I watch from Hulu, and buy the rest, still cheaper than cable. I would have to figure out how to get NBA games though.... I need my Lakers.
