Corsair Obsidian 750D Full-Tower ATX Case Review
The Obsidian Series 750D Full-Tower case is designed to mount a standard ATX style power supply at the bottom. The power supply slid easily into position and is secured with four screws on the backside panel. It would have been nice if Corsair had provided a padded PSU support/mount to help eliminate vibrations but they didn’t. The power supply can be mounted either with the fan up to pull air out of the case or with the fan down. The dust filter covered opening on the bottom of the case allows outside air into the PSU when the PSU is mounted with its intake fan down.
ATX Motherboard and VGA Adapter
The 750D case is designed to accommodate XL-ATX, E-ATX, ATX, or Micro ATX motherboards. To see how things line up we installed a standard ATX motherboard and VGA adapter. There is a large cutout behind the CPU socket area and the case uses raised pads for standoffs to mount the motherboard. The motherboard slid into position easily and mated up with the mounting holes and rear I/O opening as expected. So did the graphic adapter. Thumb screws are used to secure expansion cards so you won’t have to worry about cards coming loose during transport.
External 5.25” Optical Drive
Our 5.25” Blu-ray player slid easily into position and locked in place without tools as advertised.
Internal Hard Disc Drives
The internal 3.5” / 2.5” HDD trays are one piece plastic. Each tray comes with four steel pins mounted in silicone vibration isolation washers that are used to mount 3.5” HDDs; just flex the plastic tray and drop in the HDD. No tools required. To mount a 2.5” SSD you just pop out the back corner pin and use the supplied machine screws to attach the 2.5” device to the tray.
The 750D includes four 2.5” SSD trays located on the back wall behind the 3.5” drive cages. The 2.5” trays are also tool-less and snap into location. They can be accessed by removing the right side panel.

Overall, this gives the end user the potential to mount a combination of up to 10 3.5”/2.5” HDD/SSDs!
