This build list is a good place to start (and to revise as needed) for someone interested in building a silent and powerful workstation PC for either professional video editing or 3D modeling. This build emphasizes airflow with a total of 8 fans inside of a well-ventilated case, but silence is attained by running the fans at a very low RPM. Three storage drives are used to achieve a fast workflow at a reasonable price point. Air cooling is chosen because liquid cooling is more expensive, only marginally better and less convenient. The video card choice is debatable because of volatile prices and some creation software needing it more than others. For example, DaVinci Resolve may benefit from a GTX 1080 Ti, whereas a GTX 1080 Ti may be optimal enough for Adobe Premiere. White LED's are included on this list for monitoring fan performance and dust.
