I'm planning to buy a SC432T-665B and I want to build a quiet workstation. In Chassis's spec, it's called "Super Quiet". If I'm right, it applies to PSU not to the whole Chassis. For this reason, I think I need to buy FAN-0104L4. (Please, correct me, if I'm wrong). Can I order this Chassis without FAN-0074L4 fans or with FAN-0104L4 instead default loud fans?
If you want to have a quieter SC743 chassis, please pick SC743TQ-865-SQ directly. If the customer still wants to use SC743T-665 chassis but w/ quieter fans, please change the middle cooling fan to FAN-0104L4 and the rear exhaust fan to FAN-0103L4.
