Corsair Obsidian 750D Review

Interior

The most appealing aspect of the Obsidian 750D for high-end system owners is the cavernous interior. It's immense and easily swallows an E-ATX motherboard and several top-end graphics cards. As you'd expect with Corsair, creature comforts are here in abundance, including ample cable routeing around the motherboard tray and a huge CPU area cut-out for easy removal of CPU coolers and waterblocks.


There's nothing blocking the two 140mm fans in the front, which are free to blast cool air towards the graphics card and CPU cooler. Despite this, though, there's room for up to six hard disks and four SSDs. The latter can be installed in four tool-free clips next to the motherboard tray on the far side, or if you're prepared to sacrifice 3.5in mounts, in the six hard disk bays too (assuming you're rich enough to own that many SSDs).


There's plenty of room behind the motherboard tray too, so hiding all your cables here won't be an issue, and all the storage mounts conveniently point here too so you have very few excuses for not building a super-tidy system. There's effectively no limit on the PSU size, and even our sizeable Antec Signature SG-650 left that both lower cable routeing holes accessible, which is a bonus. The PSU is also backed up by it's own fan filter, with the other covering the two front 140mm fans and is also easily removable.


As for water-cooling support, the roof is your best option as it can house either a dual 140mm-fan or triple 120mm-fan radiator with ample room for full-height models and a row of standard fans too. The bottom storage mounts are removable, which both frees up the front two 120/140mm fan mounts and two 120mm fan mounts in base, both of which support respective size radiators. However, as well as losing all your 3.5in mounts you won't be able to fit dual-fan radiators in both these locations at the same time.
