Thirty thousand dollars? get an i7 6950X (~2000), asus rog maximus x99 (~450), 128GB DDR4 3600 ram (>1000), Seasonic snow silent 1050 (250), samsung 950 pro 1TB (>1000), 5x 2TB Samsung 850 evo (~1000 each), 2x Titan X (>2000), 3x 27" 4K g-sync monitors, your choice of high end mechanical keyboard (lets say $250), high end mouse ($100). That is the top you can get, and you still have enough money left over for a few years of 100mbps bidirectional data
