There were further details on the NEC support site (http://www.nec-computers.com/support2/index.asp) which, as of February 2016, is not responding.
In the first instance I used brute force and ignorance. When I came to reassemble it I discovered how I should have taken the cover off. Having removed the obvious screws on the back panel turn to the base. Here there is a small expansion socket surrounded by a rectangular cover. Remove the two securing screws and lift off the panel. At this point you should find that the top cover slides just under 1cm to rear after which should be able to lift it off.
The D380 requires a 12V supply with the usual coaxial connector. The PSU supplied with the unit is rated at 4.0A. (It draws ~4W on its own with nothing connected to it).
Both the Flash memory and the RAM in the D380 are easily replaceable.
The standard flash is a "DiskOnModule" that interfaces via the 44-pin IDE connector. A hard disk drive works equally as well. If you remove the DOM (which I did for the photos - see right) you'll find that there is also a Compact Flash socket fitted to the motherboard. Adjacent to this is a jumper (JP1) that allows the CF socket to be configured as either the Master or Slave device on the IDE interface.
Next to the CF socket there is a single SO-DIMM socket for the RAM. The RAM is a 200-pin DDR2 667/533 SODIMM. The 512MB one fitted to my D380 is made by Transcend and labelled 512MB DDR2 533 SO-DIMM CL4.
On the other side of the CF socket is a mini PCIe socket where you could fit a Wireless card. Three aerials for this are already fitted in the D380's housing. In the photo you can see some wires and a 'black blob' near the socket. The 'black blob is a bit of fabric wound round the three connectors for these aerials.
