Hey everyone, I had a few questions about a new build I'm doing to replace my old set up (since it's almost 10 years old lol) and was hoping someone could kick down some general knowledge since it's literally been than long since I've built a computer. If you can believe it I'm replacing a 780i FTW board with a lapped Q9550 that's been running at 3.4 GHz for almost 9 of those 10 years lol. It's finally just gotten to slow and starting to show it's age so I'm going with a new set up. I bought a Z270 Classified with an I7 7700k processor and I was wondering what you guys recommend as far as doing the OS install and if I'll need to do any bios updates. Should I do a clean OEM builder version from disk or is there a better way to load it up? Also this is my first time using a SSD as my boot drive and main hard drive, are there any things I need to look out for when setting that up? Lastly, is there a way to hook up my platter drive from my old set up that has a ton of info, pics, music, ect. to the new board? Not sure if the newer SATA ports are backwards compatible or not. Thanks in advance for any help. All is appreciated :)

Thanks Jose, I actually already have a copy of windows 10 pro 64 on disk that a friend gave to me for this build, but if you think the other way would be better I'll check it out. Would it be that much of a problem if I went from disk? I would have to do updates for the newer versions after the install no? Which honestly wouldn't bother me all that much. I could just leave it running while I'm at work lol. Glad to know the hard drive is good to go, thank you. I was wondering though, the old drive has the version of windows 10 I have now (which was the free upgrade they did a while back online for some windows 7 users) is that going to interfere with the new set up and new OS when I go to transfer the data? 

if your windows key is tied to your account it might transfer over to the new build once you sign into your MS account and activate it. personally i would have just the SSD connected while you install the latest build of windows, less chance of it trying to span the drives that way. once up and running on the SSD connect the HDD and copy any data off it and then format it for mass storage provided it doesnt give you any errors about age. 

The thunderbolt port is one reason I keep my Z270 around and if no new Mac mini's on Oct 30 I will be right behind you on building.
My EVGA Z370 is working VERY well for Windows 10 stuff.
