Unfortunately not ... there is not enough room at the back of the laptop to do that .
There is barely enough room for a usb .
I would like to add that the reason I built the spinner was to see if I liked how a home built spinner worked. As of now the spinner is in it's own wooden box but in order to use the spinner I have to lift the computer out of the case and use the spinner through the ps2 port which is one the right side of the computer. Very much a pain in the arse.
I do like the spinner's feel, but now I wan't to incorporate it into my cp and I can't do it without a usb ball mouse.
BTW....Gozur thanks again for your help with the trackball mouse. I am still looking into making this work Death Dealer made a mini cab with a trackball made from Logitech Mable mouse. I asked him for pictures to see how he accomplished this. So who know I may still buy that from you
