Corsair's case lineup has been growing over time with a trickle down approach, as they launched with the venerable (and expensive) Obsidian 800D and have been able to shrink all the way down to the Carbide 200R. Yet outside of the Obsidian 900D, their enthusiast high end (as opposed to the obscene beast that is the 900D) has actually remained relatively unchanged. Today the Obsidian 750D launches, covering the space the 700D and 800D used to occupy while trickling down the 900D's industrial design.

The "lip" that was on the Graphite 600T has become a part of the ID for Corsair's new Obsidian cases, and I like it. Corsair has actually turned it into a fairly smart, useful design cue; there are no unsightly vents on the front fascia of the Obsidian 750D, but the large plate at the bottom is actually almost totally ventilated in the surrounding area. It's a slick design. The black aluminum fascia suits the 750D and allows it to stand out even amongst other "black monolith" style enclosures. Corsair has also taken to using large square windows on the sides of their cases, and these sharp angles suit the rest of the ID well. Whoever is handling ID over there should be proud.

The interior of the 750D is a pretty bog standard case design, but it sports all the usability I've come to expect from Corsair. Both 3.5" drive cages are removable (or stackable), and toolless 2.5" drive cages line the back off the case (one of mine was jostled slightly in shipment). Corsair has been experimenting both with doing away with 3.5" drives (the Carbide Air 540 only supports two) and toolless 2.5" drive mounting methods, but the fly in the ointment for the latter has been the increasing popularity of 7mm drives instead of 9.5mm ones.

Air cooling is handled by a pair of 140mm intake fans and a 140mm exhaust fan; there's space to mount additional fans (or radiators) in the top of the 750D as well, and a large magnetic "sheet filter" is in place on the top of the case. Interestingly, Corsair has forgone including a fan controller with the 750D; instead, the 140mm fans are just tuned to what will hopefully be a happy medium.

The Obsidian 750D is essentially hitting the mainstream of the high end. This is a fairly competitive market, and it behooves Corsair to have a strong entry at the $159 price point. What's interesting is that while one of Corsair's main competitors, NZXT, is cramming their cases full of useful features, Corsair seems to be stripping them down to the essentials. The interior is primarily modular, sure, but there's no fan control, no acoustic padding, no funky LED lighting, nothing like that; this is a streamlined enclosure that seems to be heavily geared toward liquid cooling. That's fairly typical of modern Corsair designs; the 900D's entire reason for being is really to be a liquid cooled system, and the cumulative 1020mm of radiator support in the 750D should be fairly telling.

    You continue to be dismissive and arrogant by refusing to even acknowledge by constant complaint about not listing the bill of materials in the spec table. Here is the spec table from the review on bit-tech.net that was also published today:

    Form factor(s) E-ATX, ATX, micro-ATX, mini-ITX
    Cooling 2 x 120/140mm front fan mounts (2 x 140mm fans included), 1 x 120/140mm rear fan mount (140mm fan included), 3 x 120/140mm top fan mounts (fan not included), 2 x bottom 120mm fan mounts (fans not included)
    CPU cooler clearance 180mm
    Maximum graphics card length 460mm (340mm in extreme low slot with storage caddie installed)

    Too bad you cannot do the same.

    And you continue to be arrogant by refusing to even acknowledge that you are a reader, not an editor. Take a powder, and cut Dustin a little slack or ask nicely. We can Google any information we want that isn't here.

    Too bad you cannot quietly do the same.

    I have asked nicely numerous times to date, but he has not even responded. The review is not complete without the build materials, and a reader should not have to search outside of the review to find out something as pertinent as this. I would have not been such a big shot and responded to one of my polite comments over the years already. Reply

    Yes but that certainly doesn't mean he's being arrogant or pig-headed about it. Dustin's pretty damn good about fielding questions/comments about his articles. Reply

    What is in that list that isn't in the table on page 1? The dust filters? Reply

    Dustin, whatever HAS happened to Antec? They really used to be the market leader in cases, and now they just seem to have whimpered quietly off into the night. Reply

    Can't wait for the inevitable cube-shaped Obsidian case. Hope they go 550D and try to make it silent, but deadly with lots of fan ports. Also, they can toss the window and give me some places for GPU cooling on the side instead.

    Too many windows of late, too few places for GPU cooling.
