Mostly looking for an i5-750, will consider 6xx and i7-8xx. Needs to be a better deal then these, http://www.microcenter.com/search/s...09&Ns=&Nso=&sht=Any&prt=NewProduct&web_group= QDCs Need the ones for 1/2ID 5/8OD. If you have others for a good price I will consider going with different tubing. Need at least two female and two male, but could use four of each. I really dont want to pay $55 after shipping for two sets of them from koolance's site. Id really like if I could get all four sets for that price.
