some (may be each) channel of the fan controller can be connected to the MB and use the PWM signal the MB sends to control the fan.

Plus RPM data of each fan can't be passed back to the MB
did not think of routing back the rpm signal to the MB, as rpm can be read through the fan controller anyway, but this might be useful when the MB/bios is used to monitor fan rpm and probably shutdown or alarm the system on failure. anyway, this can be implemented easy.

it requires a bay, which I don't need
no bay required here. the fan controller is a box to be mounted anywhere. but keep in mind, as the fan controller will use linear voltage control it will need some airflow to keep temps under control when high load fans are used. this should not be an issue when using standard fans which draw less than 250mA (most of the fans out there will fall into this category). anyway, max possible current per channel will be 3A. not decided yet how many channels will provide this.

And the input 4-pin molex connection is only suited for 60-80W, so even running 2-ch at full capacity could get dangerous.
have to check the specs to see what a single 4pin molex is able to supply. if one is not capable of doing the job, i might consider using a second one but i doubt it will be required.

And I may eventually replace the AP-15's on my Rad with 2x 5400RPM GT, if testing of 1x goes well.
powerwise this should not be a problem.
