I decided on an SSD for the boot drive, this box will eventually be replacing another home server and I wanted to make sure MySQL would be quick. The WD Red has been formatted as XFS and devoted entirely to MythTV recordings.
Other than some hiccups with activating the CableCard this build went really well! The case is very tight to work with in some areas but otherwise it's super nice and looks really sharp. My only complaint is that the front USB ports are extremely tight, when I plug something in it feels like I'm forcing the cable in backwards.
It's unbelievably quiet, especially after I turned on PWM for all of the fans. And speaking of which, it's great that the Noctua fans all come with extra cables. I made use of the Y-splitter and extension cable for the front fans which would not have reached otherwise.
I installed Ubuntu Server 14.04 LTS and the MythTV backend which went fairly smoothly, it's a very quick machine. The load during recording and transcoding is low.
Very nice case, looks super sharp. My only issue is that the front USB ports are very tight, when inserting a plug it feels like I'm trying to force it in backwards.
