RetroTower is a completed miniature desktop decoration that recreates the appearance and startup atmosphere of a 386-era PC. The front panel combines a CPU-speed display showing 33 MHz, a power LED, and a blinking hard-drive LED. The lights reproduce familiar visual cues from early desktop computers.

A miniature buzzer supplies simulated boot-up sounds. These include fan spin-up, RAM-check ticking, a POST beep, floppy-drive noise, and hard-drive ticks. The result pairs the illuminated front panel with the small sounds associated with starting an older computer.

The enclosure is 3D-printed and spray-painted to resemble aged, slightly yellowed plastic. Its details include air vents, a power-switch detail, decorative 5.25-inch and 3.5-inch floppy drives, and empty drive-bay replicas. The drives and bays are decorative, and the finished piece is not a working computer.
