A:Answer As you already noted, the PC has 4 case fans. 3 for intake and 1 for outtake.
On top of that the CPU cooler fan as well. The fans are thermaltake. Nothing is proprietary in terms of hardware components, making it easy to upgrade parts, although the case is spacious and a clean look, you will be limited on upgrades such as an AIO, even a single fan AIO cooler. An AIO requires a swap to a new case, which is no problem.
