$280k to charities, $250k to production costs, $250k as bonuses to his staff, and $220k for himself.
I just built 20 PCs at approximately $1200 per machine (including my markup/labor and Windows 7 pro licenses) for a company in St Paul, Minnesota.
Core i7 870
8GB G.Skill DDR3-1600 (9-9-9-24)
320GB 7200rpm Seagate 7200.12
XFX Radeon 4870 1GB
ATX mid tower
Windows 7 Professional
I beat the hell out of Dell's quote for their required specs (they had a mid-range Core 2 Quad, 8GB of DDR2, and dual Radeon 4550s for that price).
They're very happy. I make about $150 profit/labor on each, and it only takes me 45 minutes to build each machine, image it, get Windows activated, and join it to their domain.
I warrant the parts as long as their built in warranties (ranging from 1 year to lifetime), and my labor for repairs is free the first year (and on-site - better than Dell's standard 1 year ship-it-in warranty).
Granted, 1000 machines is different - but if you get a small army of people that can build as fast as I can, and if you choose good components and make a good base image, it's certainly do-able.
