4-pin PWM to Molex fan, Does it exist?

it could work using this perhaps

I am trying to figure out if I can get away with buying a single one, or if I will have to hook one up to every fan...  Ebay does seem to have other options too, but all more expensive and uglier.

Well, with that, you'd just be running the fans at full power. No fan control / RPM readout.

 

Ah, I thought about it, you can't really control the Molex fans on your case since they don't have a RPM readout (The third pin on the three pin fan header). Your motherboard would need some kind of RPM readout to know what to adjust to.

So a simple DC 0-100% could not work?

For the Best builds and Price lists here is a world where many points of the price have been predefined already for your convenience!

The Xeon E3 1231 V3 IS BETTER Than the Core i5 4690K and a Significantly better value for the non-overclockers or value shoppers.

The OS is like a kind food, Try it before saying if you like it or don't.

Get some potentiometers and put one in line with the power to the fan. It's manual but the only way you're going to do what you want without getting a pwm to 3 pin fan hub

Well, if you have a way of controlling the voltages, it would.
