Mini-ITX music studio rig for professional music & video production as well as other content creation.
Compact, powerful and packed with features. Large storage capacity with room to upgrade. Went with an RX580 to stay within budget but not skimp on the quality of the other parts (5500xt wasn't out yet) And the user doesn't game much (might change now that he has a rig that can XD) Easy upgrade if he decides to go in that direction.
Stock cooler works well enough for the type of use it's getting right now, but will most likely put an aftermarket cooler on it soon.
