Someone built their own Steam Machine. Components came to $700 without the case.
Bulk discount normally runs at around 10%. Case, I guess at $30. So Valve likely pays $650 for parts.
That leaves them with about $400 for assembly (probably $50-100), support (around $100), development ($50), sales and marketing ($10), and inventory ($10-50)
So, somewhere between $50 and $100 in profit per machine. Not a good deal for Valve
