 yyyeeeeh, i thought about that.  it's _really_ tight.

 yes, but there's at least 2 USBs.  there's a jmicro USB-to-SATA part
that's reasonably low-cost.

 no - although if it's one of those standard parallel port
memory-addressable buses then a DM9000 ethernet PHY would be happy to
go on it.

 yeah.  let's assume a 1.5mm thickness.  0.5mm for the B2B connectors
(that's generous).  1.5mm for the CPU and other parts; that's 3.5mm -
you're already 1mm over the budget, even for fitting onto a 1.2mm
thick PCB within a 5mm PCMCIA case.
