I really like the aesthetic of the XE line (I also love the XL one, but not mixed up) which is the same as the ST line. So why not to use a SF3x4 drive 3.5" mechanism and case, and then create a XF551 PCB with new smaller dimensions, like the new XF551 PCBs produced by Dropcheck but everything squeezed.
I would love to see that drive working along with a 130XE, XM301 modem or XC11 cassette recorder, for example.
The xf551 with 3.5 mech just look weird.
It is just an idea, no real practical use, but it should be very very cool.
What do you think, pals and gals?
