PCAudioLabs is a boutique computer builder based in Nashville, Tennessee that specializes in PCs and laptops optimized for digital audio and video production. The company assembles and configures desktop towers, rackmount units, and mobile workstations under its Rok Box product line, including the MC-X desktop/rackmount series, the CR series, and the MC Mobile laptop series. Systems are tuned for low-latency performance with DAWs such as Pro Tools, Cubase, Sonar/Cakewalk, Ableton Live, and Studio One, and are sold with configuration options aimed at tracking, mixing, mastering, post-production, and live performance use.

Founded in 2000, PCAudioLabs has supplied machines to and partnered with music software and hardware companies including Steinberg, Cakewalk, Roland, Yamaha, and Euphonix. In 2013 the company was acquired by OBEDIA, a music recording software training and support firm, and the two operations are run together with shared technical support resources. The brand is a common point of discussion on pro-audio forums such as Gearspace and the Cakewalk community, where it is known for its focus on turnkey, audio-tuned Windows systems rather than mass-market gaming or office PCs.

PCAudioLabs has 4 products cataloged on Equipboard, including Computers & Peripherals. Their gear is featured by 1 artist, with the strongest followings in Electronic and Rock. Notable users include Bon Harris.
