3. MCP350 and MCP355 already have their power wires on a 4-pin molex connector and the tach wire on a separate 3-pin connector. They probably replaced the 3-pin by a PWM style 4-pin and kept the PSU style 4-pin molex for the power wires.

4. I think Swiftech said they were switching all their PG11 fill port to G1/4, probably the case here.
