I'm looking to get a Mac Mini for a home theater setup. Do I need the latest model, or can I buy an older one? I know I need at least an Intel Mini. There's a guy in my area selling a Mini for $300. 1.83 core 2 duo 1GB ram 80GB hard drive Will that be good enough? I could always upgrade it to 2GB ram and a bigger, 7200RPM drive if needed. Also, my TV is 720P, so I think s-vid would be enough. Not sure that I need HDMI. Thoughts?
