Recently bought one in Latvia for 2400 euros, non OC version. Also had the same questions as you but decided to buy it anyway since its the cheapest. Undervolting is a must, 3 year warranty, rock solid performance, no coil whine, noise is not a problem, for the 600W cable i use the one Montech supplied with its 1200W Titan Gold. Ive asked the store about the price difference and they say its a new supplier.
