In general it's better practice to put the resistor on the positive wire, though in this case it doesn't really matter. The resistance can be found with ohms law, there the resistance is V/I, where V is the voltage lost over the resistor and I is the current though the resistor/fan at that speed, so...

You could maybe hack something together from an aluminum plate and some power-resistors (just put your feet on it), there are also (at least here in sweden) heaters without a fan (mainly meant for mounting on walls but small ones can be free-standing).

That doesn't sound all too impossible, probably the sound arises from a region where the sheet is joined to itself (to form a closed loop). Try pinching down on that area and shake it and see if it's gone. To get rid of it permanently you could either try to open the seam up and put in some hot-glue...

If the transistor in the PWM controller has an issue with back-voltage applied to it, how about having something like this? (you will need to increase the delivered voltage as the diode has a voltage drop and the resistor will take a bit of power). http://img381.imageshack.us/my.php?image=temp1ic0.p...

It may also be some software instability. Test loading some live-cd based linux distro (boot entirely from CD, loads into ram, harddisk not touched) and see if that is stable. http://www.knoppix.org/ could be a good start.

That heat level is quite low, AFAIK many SPCRers have temps much higher (typical temps of 45°). Check that there isn't a third thing that is incorrect (improperly inserted ram, power cable etc etc).

If you dont care much for the aluminum then the CoolerMaster Stacker 810 is very good. It has space for extremely many harddisks (dont remember ATM, over 10 I think) and has very good cooling (ths entire front side is a mesh, and has two 120mm openings on the back).

Lead as vibration-damping if a harddisk is screwed into it will not help much, that it is soft and can be bent by hand does not make it absorb sounds (the steel used in cheap cases can be nearly as soft if properly treated).

No "computer" fans will work by swapping the wires, as they are brushless and therefore have electronic components that sense where the hub is and apply a magnetic field accordingly.

If you manage to get air from some other thing blowing past the zalman then you will probably get sufficient cooling. bending up the cooler completely will make it cool better, as it will be easier for air to come into it.
