I was so impressed with how well the X4 worked for me I decided to get the X5 from Charter Oak. Actually two (2) of them. I sent off my deposit check the week before last, and now I get to sit here and wait. Estimated delivery date is in March. My X4 arrived with a stand and coolant setup, but I decided to go with the PRO setup on the X5s. Hopefully that will allow me to get them up and running faster than the X4. I built my own enclosure and splash guards for the X4. The X5s will come with them. There are several things in chip management that look "better," but according to the pictures they still have those narrow throat plastic coolant valves I didn't like with the X4. Fortunately I bought a bunch of those chrome plated brass ball valves I used on the Hurco, TKCNC, and X4 coolant systems.

Well, not much else to say until they arrive.
