Corsair has introduced the newest member of its top-tier Obsidian PC chassis line, the 450D.

The 450D is the smallest chassis in the Obsidian series that can fit an ATX-spec motherboard. The 350D and 250D are both geared towards mATX and mini ITX systems, so the 450D is intended for users who want a scaled-down Obsidian chassis for their ATX motherboard-based systems.

As befits an Obsidian chassis, the 450D is designed with optimized cooling in mind. Accordingly, it comes with a pair of 140mm AF140L fans installed in the front intake position and a 120mm AF120L fan for rear exhaust duties. The two 140mm fans are positioned to facilitate a direct line of airflow to the GPU area. Incidentally, this is the first Obsidian-class chassis with an open fascia panel.

Speaking of cooling, the 450D can also support up to four radiators. Users can install a 120mm radiator in the rear exhaust position; they can also fit one as big as a 360mm radiator on the roof. A 280mm radiator can sit in the front intake position, and up to a 240mm can sit on the floor as well. Fan filters are fitted in all of the intake positions too, so all those fans shouldn’t suck a ton of dust into the chassis while they’re working.

A plethora of other enthusiast-approved features abound in the 450D, including tool-free removable modular hard disk mounts, SSD mounts on the motherboard tray’s rear, tool-free drive bays, a pair of USB 3.0 ports in the front I/O cluster, and seven PCI expansion slots. Oh, and it also has the signature Obsidian brushed aluminum fascia.

Corsair says its Obsidian 450D is available in April. MSRP is $119.99.

    If this could support a 480mm radiator sans mods, I’d be tempted to say that this is my favorite Obsidian-series chassis.
