So this has come up in the past, wanted to get opinions from the technorati out there (I'm looking in your direction Tim Sassoon, I think you built one a few years back, yes?)

Have been toying with building a mac mini render farm, mostly for cinema 4d.  With the just released i7 quad core mac minis… thinking it could be a pretty great option.  I know you can probably get more bang for your buck building a PC based version from scratch.  But one of my concerns, being in a relatively small studio space is power consumption and heat, which I think makes a mac mini a good option.

Just not sure how stable they are for sustained multi hour usage on the processors….

Any thoughts?
