I'm looking to move my ATV1 to the bedroom & purchase a used or refurbished mini to be used in the living room as our home theater system. 99% of its use will be to play 1080P/720P encoded movies & music. Some questions for the mini experts & those of you that use a mini for the same purpose I am wanting to do. What specs will be good enough to play back these movies? Will 4g ram be enough? I'm guessing I'll need to upgrade it to at least 8g unless others have used a mini with 4g with no issues. What about the Intel HD Graphic cards? Are they enough to play 1080P movies on a LED TV? Thanks for your help.
