Yep, a straight copy would be somewhere around there, for all new components at usual hydro shop retail rates.
Keep in mind this system comprises 5 fully independent flood/drain tray systems, 1x 400HPS & 2x 1000HPS, along with cooltubes, centrif ventilation blowers, dehumidifier, thermostats, thermometers, lots of small electrics and cabling, nute & pH meters, nutes, pH test & correction goo, media, pots, sulfur burner, circ fans, air pumps & bubble curtains, drain valves, etc etc etc.
You don't have to start on this scale; you can start 1/2 scale with a single 1000 HPS. If you had 2x 900mm x 900mm trays, you could feed in about 12 plants every 2 weeks, running 48 total plants.
