NB: I haven't removed the heatsinks but, when running Tinycore Linux, an lspci identifies the graphics chip/driver as: CN700/PM4800 Pro/PM4800 CE/VN800 [S3 UniChrome Pro]
For those to whom it matters here is some detail from Linux's /proc/cpuinfo

The unit uses a small external power unit rated at 12V @4A. The connector is the usual 5.5mm/2.1mm coax plug.

Flash: This is easily replaceable. The V90L has a DOM in a standard 44-pin IDE connector. This is a vertical DOM plugged into the socket in the top left of the photograph. (No DOM is fitted in the photograph and the socket is lurking in the shadows).
RAM: The RAM is provided by a standard 200-pin DDR2 SO-DIMM. The one fitted is labelled 512MB 2Rx16 PC2-5300S-555-12 made by Hynix. The part number is HYMP564S64CP6-Y5 AB-C. The product literature implies that it supports up to 1GB of RAM. I have successfully used a 1GB SODIMM but note that this must be a low density part. i.e. It should have eight chips per side, not four. In my experience the labels of such SODIMMs carry a 2Rx8 designation rather than 2Rx16. i.e They start 1GB 2Rx8 PC2-.... If you use 1GB high-density part it only appears as 512MB. (See here for an explanation). On power-up, if you've disabled the display of the Wyse banner in the BIOS, the BIOS does briefly display a DDR DIMM speed of 533MHz which indicates that my PC2-5300 part is actually running at PC2-4200 speeds. This matches the CN700 and CN800 specifications of supporting DDR2 533/400.
USB: In a similar way to the V90 the V90L has a spare header on the PCB - it's the yellow socket at the top middle in the photograph. When running Linux a lsusb -t shows that Linux has found five USB ports. Plugging a standard motherboard plug-to-two-usb-sockets connector in to the spare header gave me two additional working USB sockets! So you do have the possibility of fitting some internal USB devices (see the Neoware CA15 page). Alternatively, if your metal working is up to it, you could fit two more USB sockets to the backpanel.
Wireless: I have one example with the factory-fit Wireless option. This uses the VIA VNT6656G6A40 USB Module/Dongle wireless board which is mounted on a small metal bracket partially fixed to the main heatsink. The Wireless circuitry is interfaced via a VT6656 chip. This is connected to the internal USB socket mentioned above.
SATA: The circuit board design does include provision for two SATA sockets adjacent to the 44-pin IDE connector. I have heard of one individual who has successfully fitted sockets to his V90LE and has connected up a couple of SATA drives.
What with a large heatsink running down the middle, the power supply components (bottom right) and the expansion provision, (two 50-way DIL black plugs towards the top right of the photograph), it is not an easy matter to drop in an internal 2.5" drive. However I have fitted one V90L with a IDE-Compact Flash adaptor and run Linux (and Windows 98SE!) from a 4GB Hitachi microdrive.
