Guidance on Selection of Intel 270 Board

My level was zero several months ago relative to dealing with the creation of an operating PC from parts, but has been raised to maybe 5 on a scale of 1 to 10; the product of studying manuals and reading forum threads by very knowable builders like you that have so willing shared their knowledge.  I was trained as a research metallurgist and have the credentials, which mean nothing, but spent a career in research, development and finally, and for most of my years, in a specialty alloy manufacturing plant - troubleshooting.  I am also very stubborn and technical detail does not bother me, but admit I am not driven to become a master hard core builder, just to build one which could be my last, but then again I did say I was stubborn.

As for your specific questions about my experience,  I have negligible knowledge of the UEFI/BIOS interface other than struggling to remember what function key or combo got me there over the years to make changes in boot order or properly identify new hard drives when installed. Back in the 90's I install in a K thru 9 public school, at the request of a friend that taught there, 60 PCs  along with the necessary network.  No, I had no prior experience with networking, routers or switches but I survived. We lost 30% of the WD hard drives the first year until I learned to not have them turn off at night - which meant I did a lot of Windows installs but never to an external. I have never installed driver software for hardware used on a motherboard except for the that associated with an upgrade of  video cards or modems. Hopefully related tech experience in numerous other areas will make up for my lack of experience here - does knowing a lot about overload protection on a 3 HP, 220V table saw and 2 1/2 HP thickness planer of any value :) - recent problems in our community wood shop?

Sorry about the inadequate description of the PSU - a product of suspecting a lot of the lengthy descriptions were unnecessary to those in the field - wrong again.  I increased the wattage to a EVGA SuperNOVA 650 G2 220-G2-0660-Y1 80+ GOLD 650W Fully Modular EVGA ECO Mode Includes FREE Power On Self Tester Power ...Model #:220-G2-0650-Y1 Item #:N82E16817438054. I picked this over a Corsair SF650.  Both are fully modular which appealed and I selected based on a couple of reviews, but know that there is much bad information out there.  I upgraded the power based on wardog's suggestion.  I did find the source of the 380W estimate he offered for my board and chased down his reference for another calculation and found that calculation even less, but there is enough experience out there to indicate more is better.

I do understand the "heat" concern but am comfortable with the case which does have provision for additional fans.  I realize "going with" the cooling fan accompanying the processor may be a mistake but easily remedied once I start monitoring temperature especially if I get into gaming.

I certainly have no fear in my capability to assemble, admittedly with only experience is replacing hard drives, upgrading video cards, adding modems and memory. Figuring out where all the wires go looks to be the most difficult.  However what you point out and what I knew when I started this adventure was that configuring and loading the OS to boot from SSD was going to be the toughest problem.  I almost gave up and purchased a Dell Alienware Aurora, an upgrade which had that feature as delivered, until I found your thread on this board "How to Install Windows on a PCIe SSD" which details that procedure.  I admit to not understanding the why's behind the detail but judged, from my own experience writing tech procedures, that it was written by a very knowledge builder.  I have tried to explore reading the manual for the board and have found all screens mentioned, but with great difficulty trying to handle mentally the menu hierarchy.  I know that will be a lot easier once I have the software on my screen.

I do hope you see a glimmer of hope in my taking on this task.  Yes, at 84 the body is getting tired, but the mind is not and I need a challenge.  I do think, however, I will buy from Newegg what they describe as Windows 10 Home - Full Version (32 & 64-bit)USB Flash Drive for the $30 premium just for insurance.  The details for making your own are numerous, and worse varied, so that is one task I have decided not to learn - hope that does not disqualify me in your eyes.
