Stupid Mac Mini HDMI connection. "I think that your monitor is a TV, so I'll screw up the color scale." I just threw away a couple of hours trying to fix that to no avail. That, and the fan that my brother has "literally never heard" isn't much quieter than the computer that I already had. And, yeah, it's audible. It's not loud, but it's sure not silent.
On the plus side, $900 has just about doubled my frame rate when playing StarCraft II on medium settings. Woo...wait for it...waaaiiittt for iiiiittt...hoo.
