Just finished my own stirplate, wanted to show what worked for me.
I decided not to use a potentiometer, and just have a single setting for my vortex. I used a 12 volt computer fan, just like everybody else. I used 2 7lb magnets from American Science and surplus. Picked up a black case and switch there. I ended up using an old lcd tv transformer and a 50 ohm 5 watt resistor I had laying around. To get the magnets away from the fan and up to the level of the outer box, I was fortunate enough to borrow the laser cutter at school and build some rings out of acrylic to mount the magnets into, it looked a lot nicer before the JB weld. JMilton1987 helped me out with the CAD files for the cutter. Also, the bar I'm using is a 2" bar.
I like the set up because it breaks down nicely and stores everything in the case.
