Corsair has done a good job of filling-out its Obsidian Series range in 2013. The range-topping 900D more than meets the needs of the E-ATX market, the new 750D handles ATX with ease and the 350D is one of the best high-performance chassis for a micro-ATX board.

The Obsidian Series 750D is a difficult product to wrap one's head around. Its model number suggests superiority to the 650D, and indeed, it surpasses the older model in a number of ways.

The script for Corsair cases is pretty much down pat at this point. You can expect ease of assembly, clean design, great liquid cooling support, and middle of the road air cooling stock performance.

this case is awesome, a lot space, The H100i fits perfect, a lot of those things to put a lot of PCI's, comes with fans, im gonna change them but those works ultra smooth, easy filters clean out, and cheap, I get it for for $99 + $10 after mail rebate and now cost $159 WOW, Glad to get it a few...

Only slightly larger than my last mid-tower case but easily accommodated my H115i AIO cooler AND a 140mm fan on the top, a 120 mm fan on the bottom along side an EVGA 850 power supply and a hard drive rack, and the two front and one rear fans that came with the case.

Good quality case with plenty of room for large graphics cards
