About the Antec Performance 1 M Mini-ITX Small Form Factor Case (Black)
The Antec Performance 1 M is a black Mini-ITX small form factor case for compact gaming or workstation builds that still need a large graphics card. Its CNC-machined chassis uses aluminium side panels and rear frame, with perforated panels for ventilation. An adjustable central mount lets you favour either a thick graphics card (up to 78 mm, 350 mm long) or a taller CPU cooler (up to 85 mm). Power comes from an SFX or SFX-L unit, the graphics card connects through a PCIe 4.0 riser, and two 120mm or 140mm fans fit in the base.
