Hello:

I still can't see it. A Z270 platform with the prices of the x299, I don't see it. SSD having M.2 either. Liquid cooling, good.
Memory 2400... with the price of the 3000. The blueray, or at least for me, is unnecessary. I think I use it once a year... if I'm lucky. And when I use it, it's to record an Xp for some old equipment.
If you're going to spend 1900€ on a computer, at least get one that will be profitable when resold.
