I don't have mouse/keyboard but that's my build so far.
Please don't go cheap out on the motherboard. The one I chose appears pretty good for the price and should have a 5-year warranty (use the CD after you install Windows. UPDATE: mean to say to REGISTER the Warranty).
*People I trust have gotten keys from Kinguin (dot net) for W10 64-bit for a lot cheaper and they seem to work just fine. You can actually download W10 (which you have to do for Kinguin anyway), create install media then if you don't pay for a license people tell me you just get a watermark and notices to upgrade (and can't modify desktop wallpaper but apparently there's a workaround).
To install W10 for Kinguin or no license you do this:
1) Microsoft site->
https://www.microsoft.com/en-ca/software-download/windows10
2) download the tool
3) insert 8GB thumb stick (preferably) or DVD-DL (supposedly but I just tried and it appears to be under 4GB)
4) run the tool, choose version (i.e. W10 Home 64-bit) and let it download and create the media
then
5) build PC
6) update UEFI (BIOS)
7) MEMTEST86 www.memtest86.com (for a full pass)
8) boot to W10 media, and install (have key if applicable; have MSN or suitable e-mail + password for login to use as account)
9) test for several days
10) Overclock
11) get another HDD of SSD eventually so you can make a backup Image
*I recommend you make the first partition (C-drive) 200GB or less, and put a STEAM folder on the 2nd partiton (i.e. E:\Steam2). Add folder from within Steam settings. By doing this you can easily CLONE the Windows partition to a 250GB SSD later then delete and recover that space on the HDD.
OTHER:
Get FAN CONTROL software from motherboard site to optimize the fan profile (i.e. 30% max RPM to 50degC then ramp up.. just an example but max CPU under heavy, real-world workload should be about 75degC)
