Since Discord is down, I'm going to try and quickly post a message here regarding my current front panel USB options for the S402. Some feedback would be great, but for now I'm heavily leaning towards the standard 3.0/3.1 dual type A connectors (option 1).
#1 - Dual 3.0/3.1 type A
Pros
1. Less expensive.
2. Easier to source and less likely to be discontinued.
3. I can get replacements in days rather than weeks.
4. Smaller front panel footprint (takes up less space).
Cons
1. No type C without an adapter.
2. Mounting hardware will be visible from the front face.
3. 20-pin connector.
#2 Dual type A and dual type C PCB
Note: I would remove the PCB from the steel 3.5" drive caddy and then install into the S402. Ignore the steel caddy for my purposes.
Pros
1. 4 front panel USB interfaces (2xType C, 2xType A).
2. Simple type A cable output (doesn't require standard 20-pin connector).
3. SATA power connector for additional devices.
4. PCB mounts would not be visible from the front (cleaner front panel).
Cons
1. Almost 3x the cost of option 1.
2. Larger footprint inside the case.
3. Getting mount points correctly could be very costly to produce multiple prototypes.
