While there are two front fans and one rear fan, its advisable to install 2 fans on top so that the 750D can live up its billing as the Airflow Edition. A dual fan CPU water cooler such as the Corsair H115i is popular with the 750D. Compatible models include H55, H60, H75, H80i, H90, H100i, H105, H110 and H115i can all be easily installed in the Obsidian 750D.

Many replace the OEM fans for LED variants to improve the appearance of their rigs. Extension cables are needed for some fan header placements. The 140mm fans are very common and every color imaginable is available.

The 750D has lots of room for even the largest power supplies. There is a filter to help keep dust out of the PSU so that it can last longer the warranty. The dust filters are all easily removed for cleaning. Corsair offers long warranties on their power supplies and they are very popular in the gaming enthusiast community.

Cable management is well supported with lots of grommeted slots and several eyes for attaching cables. The drive cages come out so it is easier to work with the cable management during a build.

There is abundant room for routing SATA cables from a card under the motherboard and over to devices, The 8-port SATA card has 2 ports on the top of the card the reset are set on the front edge. Longer SATA cables may be needed to reach the top SSD. Power cables are easily routed with easy access on top for the EPS12V cables which is an advantage only seen with full tower designs. The 280mm class water coolers, as shown, fit the Obsidian 750D easily but longer ones will interfere with the drive bays.

Placing an optical disk in the 750D may be hard to reach which is why longer SATA cables are widely available to reach down to SATA1. Extensions and longer cables as needed for fans and SATA etc are widely available. Zip-ties keep everything secure but maintainable. The 750D also has several eyes for attaching cables to prevent them flopping around.

The rear caddies for SATA SSD do not stay properly put so a third disk cage can handle more storage as needed. The slide out disk carriers can handle both sizes of disk easily. A third cage is $9.99 each so stacking 3 of them for a massive amount of storage is possible.
