My server is done too. Here is what I put into it:
Main components are the 120GB SSD, blu-ray drive, i5-4430, 8 GB of RAM, and six 3TB drives.
And the finished server. It is sitting right behind me at the moment because I can rip my blu-rays faster on it than on my primary desktop. So it still has a keyboard, mouse, and monitor hooked up.
Working on the HTPC now. It is in the following case:
The main guts are:
8GB DDR3-2400 RAM (super fast)
Asus Radeon HD7790 video card
Pioneer blu-ray burner
Way more processing power for the server and the HTPC than what most would want/need, but I am looking to do some serious video processing for the optimal picture and that takes more horsepower on the CPU and of course on the video card.
Crazy thing is that the HTPC boots up from power off to fully up in less than 15 seconds (that is INTO the HTPC software too).
