The primary purpose of this build was to replace an older build with off-the-shelf components, all fitting within a sleek and compact form factor. One of the primary functions is to serve as a sort of a homebrew Time Capsule to backup my workstation and laptop.
I selected parts based on the idea that this device would be left running 24/7 and system stability was important. With that in mind I selected a processor and motherboard that would be compatible with ECC Memory. Without it, then one could easily reduce the cost of this system.
The case was chosen because I wanted something that would look professional on my desk or look at home as an HTPC, not take up too much space and house components that were a standard form factor.
As an option I also wanted to be able to mount a 3.5" hard drive. That is not a feature of the Dan A4 however, using the official optional 120mm AIO bracket along with a generic 3.5" HDD adapter bracket, mounting an HDD on the GPU side of the case is easily accomplished.
