Finally I decided to build my Ethereum rig with 6 Gtx 1060 (6gb version). I would have some questions:

-How do I check what type of RAM the graphic card is? It is true that only Samsung and Micron RAM allow a good overclock? Wich GTX 1060 brand should I choose?

-What kind of power supply do you recommend? 850w is ok?

-Ram? 4 gb should be ok... DDR 4?

-Motherboard and cpu: A normal Celeron would be ok, right?. Wich one exactly? I obviously also need to find a motherboard that supports that type of cpu. ASRock maybe is a good choice. Wich model should I choose?

Thank you!

The general trend for overclocking potential appears to be Samsung > Micron > Hynix. However, the silicon lottery will still make things vary chip-to-chip, so once you have your specific units, it'll be up to you to mess around and find optimal settings on your own.

The top three factors for selecting different card variations on the same GPU+memory size are: Price/availability, cooling design, and power connectors. (Card manufacturer and factory clocks are minor considerations.) In general, for an open-air configuration, I'd avoid blower-style cards unless they are the only model available or if others are significantly more expensive. Cards that require more power connectors can be a pain to deal with, although for *most* 1060s, the only difference should be 8-pin vs. 6-pin power. (And a 1060, even overclocked, shouldn't constantly push an 8-pin power connector to 100% of the 150W spec.)

For PSUs, buy a PSU done by a reputable OEM, such as Seasonic, FSP, or Super Flower. HEC, CWT, Sirfa/Sirtec are *meh*, and I personally wouldn't rely on their PSUs for heavy loads 24/7. Branding is less important than the underlying OEM.
After that, look at the total power rating and the number of connectors. Most 850W PSUs are going to be a pain to scrounge up enough connectors for 6x 1060s, and you'd be cutting it a bit close in terms of overall power, even after changing power/clock settings.

For system RAM, 4GB is fine. DDR4 vs. DDR3 isn't a big deal for mining; it just has to match your motherboard choice.

If you can get a Pentium processor for a similar price, I'd go for that instead of a Celeron. Some mining software makes greater use of the CPU than others. However, a Celeron *should* suffice in most cases.
