The assembly
If the previous photos didn't make it clear how frickin' big the 750D is, this one should.

The 750D is so big that it dwarfs our ATX motherboard. For the most part, that's a good thing. We didn't feel cramped while putting together our system, and there was plenty of extra space to run cables and make everything nice and tidy. The only notable exception was the power supply; with the drive cages in the default position, there wasn't a ton of room behind the unit. Moving cages around—or removing them altogether—is always an option, though.

Our only gripe with the 750D's huge dimensions is that, depending on where your motherboard's three-pin fan headers are located, routing the wires for the two front fans may be awkward. In our case, the wires were almost too short to route behind the motherboard tray. The pictures above show one of the wires going right across the belly of our SSD and reaching diagonally up toward the mobo.

We had no problem with the other cables, though. Even the processor's auxiliary 12V power cable had an acceptable amount of slack when plugged in.

On the storage front, installing hard drives was as simple as snapping them to a 3.5" drive tray and sliding the tray back into the case. The optical drive installation was similarly easy. We just removed the front cover and slid in our DVD burner until it clicked into place. To release it, we simply pulled the tab and pushed the optical drive back out.

The four side-mounted 2.5" bays were also fairly simple to use, although they did complicate cable routing somewhat. We had to be careful, for instance, to run the fan wires between the cages rather than through them. Otherwise, taking the cages out would have required unplugging the fans first.


Minor niggles aside, building a PC inside the Obsidian Series 750D is pretty much like what you'd expect from working with a Corsair case. In one word: painless.
