The XSPC D5 tank reservoir is relatively cheap at $40, and D5 pumps are usually in the $70-80 range. It'll be slightly over budget at $110-120 for pump and reservoir, but I think that's the best option you have.
The D5 tank reservoir currently sells at $35 at Performance-PCs.
If budget is the issue you could buy a D5 or 35x and buy the res later. a 35x with 35x res would give you the most power and with speedfan you could set it up to auto throttle speeds depending on temps. Fcpu caries the new mcp655pwm which.is also PWM
