Don't worry about that, each and every post that is discussed by the people in the US or any other country, and all the parts that they are using is pretty much available everywhere and its a good place to start. Try finding a good motherboard with 6 PCI-e slots, get the budget CPU which supports the socket of your motherboard, 4 gigs RAM, 32 GB USB Stick if you're going to use Linux or else 120 GB SSD for Windows 10. It might feel a bit daunting until you actually try it.
Any recommendations for the Motherboard? Without burning a hole in my pocket...
I was thinking of a LGA 1150 socket model but most have only 1 or 2 pci-e slots except the ultra expensive.
ASUS Z270-P
MSI Z270 GAMING PRO
MSI Z170 GAMING M5
Literally, any Motherboard with 6 PCIe slots which doesn't depend on lane sharing in PCIe lanes is good to go.
Hello Akaash: I wouldn't waste time on non-BTC specific Motherboards. I have built 4 rigs so far with 4 different MB's and from that experience, I highly recommend getting either ASRock H81 PRO BTC R2.0 or Biostar - TB250-BTC .
Also look at 1stminingrig blog, couple of useful posts from it are: http://1stminingrig.com/best-mining-rig-hardware-mine-2017/ and http://1stminingrig.com/tutorial-ethereum-mining-rig-part-1/ (also read parts 2 through 4).
Feel free to PM me if you have additional questions or ask on this forum. Good luck!
