The R90L is larger than a lot of thin clients, standing some 25cm (10") high. In comparison with most thin clients covered on this website it is quite modern, my version being manufactured in February 2010. I believe the range was launched towards the end of 2008 and most were retired by the end of 2012. (See bottom of the page for details).
From Wyse's publicity data:
The new Wyse R90L thin client features high performance central and graphics processors coupled with full support for multiple screens, and the best PC experience available on a thin computing platform with Wyse TCX software.
The Wyse documentation suggest that the R class L family share a common hardware base. The variants are all to do with the amount of flash/RAM fitted and the embedded operating system.
If you compare the specifications for the 'L' and 'LE' you will find two significant differences. The 'LE' includes two additions:
...from which we can deduce the 'E' bit of 'LE' probably stands for 'expansion' capability.
I also note that the 'L' version stands some 250mm high whilst the 'LE' version is 307mm high. I've added some photos to the R90LE tab.
I bought my Wyse R90L back in November 2012. In June 2015 I got an email from Rick who, on the basis of what was documented here, bought an R90L on eBay. When he opened it up he was disappointed to find that there were no PCI or SATA connectors fitted - in fact the board doesn't look as if it is tracked for the SATA connectors. A bit of a bummer as he'd bought it for that expansion capability. It transpired that we'd bought slightly different models - my label is on the left, his is on the right:
At the time Google failed to find me an answer to this anomaly.
I recently (February 2017) spent a while seeing what I could track down. Eventually I found an old Wyse publicity leaflet dated 2008 where the R class 'L' family are shown as being fitted with a 1GHz AMD Sempron processor. In the (undated) Dell Wyse R class publicity leaflet that's the more usual one you come across it's shown as being fitted with a 1.5GHz AMD Sempron processor.
From this it's clear that at some point Wyse updated the hardware without changing the model number. At the time, based on the two labels, I assumed that you need to look at the part number to see what you're getting. (Model numbers and part numbers are at the bottom of the page). I assumed, where there are two part numbers, the lower numbered one is for the earlier model. What's documented here is the later version.
In May 2017 I heard from Timo who sent me photos of his R90LEW (909542-02L, manufactured March 2011) showing it was fitted with a SATA socket. Previously (October 2015) I'd heard from Onno that his R90LEW (Same part# 909542-02L) had no SATA socket. From this I can only deduce that at some point Wyse updated the motherboard to include SATA support without any change in the part number. From the limited information in my possession this would appear to be between July 2009 and February 2010.

The power supply is a 19V 3.4A Liteon PSU that requires a clover-leaf style mains lead. Note: The 19V rating. If, like me, you have a number of PSUs and thin clients floating around you need to mark this PSU clearly in some way. I'm sure that those which run from 12V - which is most of them - would not take too kindly to 19V. The coax plug is 5.5mm/2.5mm.
This is fairly straightforward. You need to remove the foot and the two screws towards the rear of the unit - one on the top and one on the bottom. After that the side cover can be slid back and removed. The plastic top and bottom covers are also loose at this time. When re-assembling the unit the one thing you need to remember is that these need to be in place before you slide the cover back on.
The motherboard is marked Rx0Ly and Rx0LEy next to a matrix which I guess must indicate which options are fitted. From this I would assume that the motherboard is common across the R series L/LE versions. The matrix is labelled at the bottom 'mercury' and 'pluto' which I guess must be internal code names for the two product ranges. Some of the internal cabling in the R90L does carry paper labels with 'mercury' printed on them.
There are also a series of small white connectors on the motherboard that probably support various factory-fit options. We have BT CONN, Wi-FI CONN, DEBUG BOARD CONN, and three other anonymous ones. Two of these (CN13 & CN15) are adjacent to the SATA connectors and I assume are there to provide power to any internal SATA devices (SSDs?). (They provide 5V). From a photo of the LE the other one would appear to be the connection point for the parallel port.
The base of the large heatsink is close to the surface of the board so I would assume the chips underneath are mounted directly on the board and are not socketed. I haven't removed the heatsink to check.
For those to whom it matters here is some detail from Linux's /proc/cpuinfo

Both the Flash memory and the RAM in the R90L are easily replaceable.
Flash: The flash is a "DiskOnModule" that interfaces via a 44-pin IDE connector. In the photo it is the small blue board with the white label.
RAM: The RAM is a 240-pin DDR2 DIMM. The 1GB part fitted to my R90L is a PC2-5300U-555-12-ZZ part (MT8HTF12864AY-667E1). It just so happens that I'd just upgraded the memory in my main Shuttle Computer and so had a 2GB DIMM to hand - PNY 64B0QJTHE8G17. That worked fine.
USB: There is a spare header on the circuit board close to the IDE connector. (Yellow blob in the photograph). I plugged a standard 10-pin motherboard-to-two-USB-sockets cable into it and found I'd gained an extra two USB ports. Interestingly these are not mentioned in the R90L technical specification, but that for the LE does say 'four internal USB2.0 ports'.
PCI-E: There is a PCI Express x4 socket.
SATA: There are two SATA sockets on the motherboard each with an adjacent white socket that could provide power for the SATA device. My brief experience here with the SATA sockets is that anything plugged into the socket by the IDE connector is ignored - both the BIOS and by Tiny Core Linux once it has booted. If a drive is plugged into the socket (CN18) near the back panel, the drive appears in the BIOS against the IDE4 designation. (See the Firmware tab).
The two white sockets (CN13 & CN15) can used to power the SATA device. On eBay these are described as "4-pin Micro JST 1.25mm" connectors (or similar). Some years ago I picked up a pack of 10 plugs with flying leads for a couple of dollars from a supplier in China. (See here). The +5V supply is on the two pins marked by the ^ symbol on the board.
Well from Wyse's site here is a list of models and when they were retired. I've added a couple of extra columns as to whether or not they have the PCIE socket fitted and SATA support. This is based on information from others. I would expect all LE models to have the PCIE socket fitted.
[May 2017]. I've recently had conflicting reports about the presence/absence of the SATA port on a R90LEW (Part # 909542-02L). This implies you can't rely on just the model number and may have to go by the manufacturing date.
