This is a high-end mITX build for both gaming and design work commissioned by my friend Rob. Rob is a man of exacting tastes and as such, it couldn't be just any old build. We went with an extremely stylish case via the Phanteks Evolv Shift which has a minimal design that complements Rob's style and helps hide cables to keep things looking cleaner.
The i7-9700K and Z370 combo will help provide good single-core speed which is helpful when working with Adobe Creative Cloud programs, for the most part, as well as gaming performance. ASUS' Z390-I offers plenty of room for M.2 hard drives, RAM overclocking via XMP, adequate fan ports, and both types of RGB connectivity port and ASUS Aura Sync for high RGB component compatibility.
We are running the system off the speedy new Corsair MP510 M.2 NVMe SSD which should provide extremely fast performance paired with the 9th-gen. Intel chip. A free Samsung 960 EVO M.2 SSD will provide extra storage and an install disk for games. The rest of the storage will be external on high-capacity HDDs that he already owns.
G.SKILL Trident Z RGB RAM provides a great, reliable, and fast memory option with good-looking lighting and is one of the only RAM kits I could find that was 2 16GB sticks that wasn't an exorbitant amount of money. mITX boards always offer limited RAM slots, so this is essential in making enough memory available for heavy usage and multitasking.
The NVidia RTX cards are overkill still and the AMD Vega cards are still too pricey, so we went with an ASUS 1070 Ti Turbo, which is a blower-style card. This will help keep internal temperatures better regulated in a case that is essentially a chimney.
Rounding out this build are a cool ASUS AIO liquid cooler with a programmable OLED on the pump head, Phanteks Halos Digital fan frames to add RGB to great fans that are included already, a separate kit with 2 addressable strips and a controller so that everything is controllable via a single software (ASUS Aura Sync), and a solid modular power supply that will help declutter a case with naturally limited space.
