Selling (US) Custom Built i7-8700k mITX Computer

Looking to sell my old computer! It's in a custom designed and 3D-printed small form factor case; making it uniquely one of a kind.

These are the parts in it:

• Intel Core i7-8700K Coffee Lake 6-Core 3.7 GHz Processor
• ASRock Fatal1ty Z370 mITX Gaming Motherboard
• GeForce GTX 1050 Ti SC Gaming Graphics Card
• CORSAIR Vengeance LPX 32GB (2 x 16GB) System Memory
• CORSAIR SF Series SF600 600W 80+ Gold Power Supply
• SAMSUNG 960 EVO M.2 250GB NVMe Solid State Drive

It's also water-cooled with a Cooler Master 240mm AIO. It's been sitting in my closet for half a year since I wiped it and re-installed Windows 10.
