Yeah heard him talk about that. 48 or so 16GB m4 Mac minis. Insane. The Beowulf lives
The ATP episode where he talked about this was incredibly fascinating. Marco is such a role model to me - he has a complete immunity to fads and trends, and just does things the way he wants to. He adopts the 'new and cool' things only when they have a real benefit.
