Centered showcase chassis

The MEG MAESTRO 900R is a full-tower case built around a centered system layout with triple-sided tempered glass. It accepts ATX, E-ATX, Micro-ATX and Mini-ITX motherboards and provides four 3.5-inch and eight 2.5-inch internal drive bays. The design targets builders who want gallery-like visibility of high-end components from multiple angles.

Vertical airflow and 60W USB-C PD

Pre-installed bottom fans use reverse blades to push air upward through the chassis, supported by mounting points for up to 14 120 mm fans and dual 420 mm radiators. The front panel includes one USB 20Gbps Type-C port with 60W Power Delivery, four USB 10Gbps Type-C ports, four USB 5Gbps Type-A ports and a combined audio jack. A dedicated LED switch controls lighting without software.

Rotatable tray and vertical GPU upgrade

The motherboard tray rotates in four orientations and detaches completely for bench-style assembly before final installation. An included PCIe Gen 5 riser cable enables vertical graphics card mounting for cards up to 400 mm long. CPU coolers up to 170 mm and power supplies up to 200 mm deep are supported. Builders needing more than eight expansion slots or a smaller footprint should consider other form factors.

商品問答

How do I install the motherboard using the 4-way rotatable tray, and what step do builders often miss?

Remove the tray, mount the board in the chosen orientation, then re-secure the tray with the locking screws — the step often missed is tightening those screws after rotation.

What maintenance will the pre-installed 160 mm ARGB reverse-blade fans need later?

Dust the blades and frame every few months with compressed air; the ARGB lighting and motor are sealed, so no lubrication or disassembly is required.

What thermal limit appears first when running dual 420 mm radiators under sustained load?

The 170 mm CPU cooler height clearance becomes the limiting factor before radiator thickness or fan count.
