Drafting a case around the Obsidian idea starts with the panels, not the parts tray. Every visible surface is brushed black aluminium, and tempered glass wraps three sides, so a build is read from the outside before the side door opens. The frame is steel because glass and radiators are heavy — rigidity under load is what keeps the doors seating straight for years.The interior is planned around a full water loop. A 360 mm radiator bolts to the roof and another to the front, the pump and reservoir ride the interior wall, and eight expansion slots leave room for multi-GPU rigs or a dual-loop build. Ten fan positions keep airflow honest even when the radiators idle, and the drive cage sits clear of the front radiator so storage never blocks the fan path.The case is for builders who treat the loop as permanent furniture. The GPU mounts vertically out of the box, so a card's front face reads as the component it is, and the riser cable is included. Before boxing, every chassis is loaded with a reference build — ten fans, both 360 mm radiators, a filled loop — and checked for flex at every mounting point.
