This replacement “drawer” for an IKEA’s Helmer cabinet transforms the cabinet into a stealthy PC, or a low cost personal renderfarm.
The existing drawer(s) are swapped out and the drawer front(s) are re‑attached to the replacement case/drawer frame(s).
The replacement “drawers” are available in various “drawer high” increments. Thus, a single drawer can be replaced with a single frame suitable for a tiny mini‑ITX rig, or five draws can be replaced with an ATX rig.
