Last I looked Mesa still has seven 7i96s boards in stock. They are set up for plasma in mind.    Its a 5v board with isolated i/o. Two of them AC ready. We got a couple and I like them. You will need 2.9 installed from buildbot though.

I have 7i96S and THCAD cards in stock as well.

Don't forget to use my Mesa Configuration Tool , it's the only one that can make a configuration for the 7i96S.

Well i am going to converting a conventional horizontal boring mill (Union BFT90/3) to CNC HBM with dual encoder feed back so i have to setup something that could handle 6 Step/Dir( 5 Axis + 1 Spindle) and 11 Encoder Feedback ( 6 Velocity and 5 Position) and and about 90 input and 40 output so originally i have planed to with 7I80HD-25 + 7I52S + 7I52 + 7I84D(X3) OR 6I24-25 + 7I52S + 7I52 + 7I84D(X3) but unfortunately 7I80HD-25 and 6I24-HD both are unavailable.

 11 Encoder Feedback ( 6 Velocity and 5 Position
I don't think that there is such a thing as a velocity encoder. 
There are tachometers, but they output an analogue voltage. (Mesa have a card for that)
Otherwise you get both  velocity and position from the same encoder, in the software. So you probably only need 6 encoder channels. 
Unless you are using motor encoders to close a velocity loop and then digital scales for position, in which case you have the count correct.

Having googled the machine, I am now thinking that this is exactly what you mean. 

And I am wondering why you are bothering with an SFF computer on something that size? I would fit an ordinary (well, probably Min-ITX) motherboard directly in one of the control cabinets.
