What graphics professional isn't assembling their own rig though? $3k is a LOT of money to spend on a desktop.
I'm old enough to remember dedicated SGI workstations, and a decade ago I felt OSX had some advantages in graphics, I can't think of any of those that exist today, at least to justify such a huge markup on parts I could buy myself.
I'm generally curious, I feel like I'm missing out, people that would consider paying $3k for a computer made out of easily-obtained components, why is it worth it to you?
