I can give you some points. Lets Build this. 1600$ here i come
(only Intel & Nvidia Build)
Get really big hdd. i.e 2x2tB drives. I wont prefer any RAID setup. WD Black being favorite. But its upon you to get SATA 3gbps, or SATA 6gbps. WD BLACK 2tB is available only in sata2 (3gbps). not that it makes any difference. Processor (oc it of course) THE BIGGER THE BETTER! from bigger i mean the powerful. Motherboard should support all latest *** and support dv cards and all, Would be good if USB3.0 is there but its rare... GPU well well well true workstation card will require alot of money, so i will suggest Gaming ones (not that they are crap) Rams should be fast and in quantity. PSU of course would be big to power all your requirements. Casing should be Good, not beast, with good ventilation. I wont go into Cooling much, may be some else will...
