Hello, I'm new to the forum and figured I'd join in and share my build with you guys!
This is my first build from scratch (using lots of tips and tricks from Linus & the gang!!) , my other PC was built by a friend a long time ago and sounded like a gang of hair dryers got into a big fight as a rocket was being launched durring a wind storm. So.... I chose all the parts with quietness in mind, the PSU has a fanless mode when under 40% load and the graphics cards are fanless under 65 degrees celcius. So, unless I'm gaming it's near silent =)
(The picture of the back is before cable management of course
