Announced on February 2, 2021 as part of Zalman’s Z‑Machine series, the Z‑Machine 500 is an open‑frame E‑ATX showcase chassis; retail listings indicate availability from May 24, 2021. Positioned as a flagship case, it exists to display high‑end builds while giving ample room for custom water loops.

Five 120 mm ARGB fans and a Z‑Sync controller come pre‑installed. The chassis uses tempered glass and anodized aluminum, offers 7 slots (riser supported), and front I/O with USB‑C, dual USB 3.0 and dual USB 2.0—well‑suited to airflow and RGB‑forward builds with long GPUs. Not discontinued. Unique: custom curved tempered‑glass front and top panels.Sourcegdm.or.jpSourcezalman.com
