my mid 07 iMac needs replacing. the hard drive fried out about a year ago and i've been running it off an external. i can hear that the fans are starting to go, the screen glitches out sometimes and the ports in the back are wobbly and things need to be plugged in "just right" to work. i'm thinking of getting a mini but not sure if i should buy new or used and if used what to look for. i don't do any "pro work" on my computer. it's main use is to feed video to my lcd television. (os 10.9 has been great for this. and i'm loving the dual monitor support but i don't really need it.) i've read that some mini's with integrated graphics have a hard time feeding hdmi to televisions, not so much for the video files but the desktop, especially when it comes to text. i'd like to be able to buy a mini that will mostly be used for watching video but will feed a good looking and usable desktop to my television on the rare occasions that i need that. thanks in advance for suggestions and advice!
