Questions about this item

What PCIe generation does the included riser cable support for vertical GPU mounting?

The supplied riser cable is rated for PCIe 5.0, so the vertical GPU slot will carry full 5.0 bandwidth without signal loss.

What motherboard form factors fit the 280 x 305 mm maximum tray size?

The tray accepts E-ATX boards up to 280 x 305 mm as well as standard ATX, Micro-ATX and Mini-ITX models.

How is the motherboard tray removed and rotated for installation?

Release the tray using the thumbscrews, lift it out, rotate it to one of four orientations, then reseat and tighten the same thumbscrews — skipping the reseat step leaves the tray loose.
