Ah yes. The Windows Tax. $200 isn't much compared to the $14,310 total price.That's just 1.4% of the total. But if you're the kind of hobbyist who claims "Ah kin built me a 'puter fer jess two hunnert bucks,"you're looking at a 50% Windows Tax (for Windows 8.1 Pro, that is.)Good luck setting all those jumpers.
