(3).- PCIe is not available on fit-PC2i becuase the two available PCIe lanes are used for dual Ethernet.
- The BIOS shares code with fit-PC2 and CM-iAM where PCIe boot is relevant.
- Other than wake-on-LAN, fit-PC2 rev 1.4 seems to meet your requirements.

...Can the FIT PC2 be booted from mini PCI-E with a ssd drive in the slot ??
1. Does the bios support booting from mini PCI-E ??
2. If yes, is the PCI-E port bootable with WES ??
(2).Many of the mini-PCIe storage cards in fact use USB interface. This will work.
True PCIe interface was not tested on fit-PC2.
Sorry for my ingenuous QsI took the time to test a few of my disks with CrystalDiskMark, and the results are quite interesting:
CompuLab stock 2.5" 160GB SATA HDD (Hitachi, manufactured July 2009)
The results are exactly the same for internal Fit-PC2 connection and connection via mini PCIe card - both sequential read and write speeds are 60 MB/sec.
KingSpec Motive G1 2.5" 128GB SATA MLC SSD (manufactured March 2010, based on JMF612 SSD controller)
When connected internally:
Sequential read speed: 90 MB/sec
Sequential write speed: 75 MB/sec
When connected through MPX-3132 mini PCIe card:
Sequential read speed: 115 MB/sec
Sequential write speed: 106 MB/sec
This gives us a few conclusions:
1) For CompuLab stock "platter" disk, the transfer speed is exactly the same for internal connection and for mini PCIe connection via MPX-3132 bridge, and both times it's lower than SSD speed limit. This hints on hard disk max. throughput limit of about 60 MB/sec (which is below internal PATA->SATA bridge limit and below MPX-3132 bridge limit). So if you plan to use regular 2.5" disks, any bus that will provide you >60 MB/sec is enough, and in particular mini PCIe card provides better result than USB 2.0 or LAN connection.
2) For faster SSD disks, it looks like the PATA->SATA bridge throughput limit is around 90 MB/sec for reading and 75 MB/sec for writing (the SSD disk itself is capable of higher speeds). So if you plan to speed-up the internal disk in Fit-PC2, installing any disk with throughput >90 MB/sec will be good enough as it's impossible to reach more. On the other hand, PCIe bridge allows faster speeds of 115 MB/sec read and 106 MB/sec write, respectively. Here it looks like 115 MB/sec is the limit of the disk, and if higher throughput disks become available, the PCIe bridge will support them.
