This is my first build, and my first desktop in several years. I am a casual gamer, and wanted a somewhat simple setup for my first attempt. So I stayed away from overclocking and more complex cooling. I only use a single 1080p 60hz display , so this is certainly capable of making games look good. I'll also do some side software development with Visual Studio and SSMS, hence the otherwise excessive memory. This will be my daily driver PC and will store all our photos and such, so I got the extra HDD's for a RAID1 setup.
So far it runs great. It boots windows 8.1 in less than 15 seconds, including keying my password.
Huge props to LinusTechTips. All his "As Fast As Possible" videos helped me understand a lot that I didn't, and one of his full build walkthroughs was also very helpful.
Also thanks to all the forum help on this site and Toms Hardware. The homework and time put it beforehand made my first build very smooth.
