About the Custom 2U Rackmount PC
A custom rackmount PC gives you maximum flexibility in component selection, allowing you to spec exactly the CPU, RAM, and storage needed for your playback workload. The 2UThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one. form factor mounts cleanly in any standard rack, and the extra depth accommodates high-performance components that smaller computers cannot house. Ideal for Windows-based playback rigs using Ableton Live, Tracks, or custom show control software where you need raw processing power and expandability.
A custom rackmount PC occupies the center of gravity in any Windows-based playback rig. Where a Mac mini or a dedicated hardware player forces you to work within someone else's spec decisions, this 2UThe standard slice of rack height: 1U = 1.75″.

If your workflow lives in Ableton Live, Tracks, or bespoke show control software and you need a machine that answers to your requirements rather than a manufacturer's product line, this is the category you're shopping in.
The catalog numbers tell a practical story at load-in. At 8 kg and 450 mm deep, this is a substantial piece of iron — verify your road case has the depth and your rack rails can carry the weight before you design the build.

A custom machine also means custom troubleshooting: driver conflicts, BIOS tuning, and thermal management under road conditions are on you. Know that going in.
In the rack
- Map your USB ports before the build is finalized — assign one USB-A exclusively to your audio interface and one USB-C to your primary backup drive, then label the ports on the faceplate so the assignments survive crew changeover.
- At 450 mm depth, measure your rack case's interior depth with the rear-door hardware in place, not just the nominal spec. Many touring cases lose 20–30 mm to hinges and locking hardware at the back.
- Set Windows power management to High Performance and disable all sleep, hibernation, and automatic update behavior before the machine leaves the shop — USB devices disconnecting mid-show and forced reboots at downtime are both power-plan problems, not hardware problems.
- Use the dual HDMI outputs to run a secondary display showing your DAWDigital Audio Workstation — the recording and playback software (Logic, Ableton Live, Pro Tools) at the center of a computer rig.'s transport or a simple clock visible from the stage floor, so band and MD can confirm playback state without keying commsProduction intercom — the wired or wireless party line connecting FOH, monitors, stage managers, and lighting during a show..
