But, as far as EMC2/Ubuntu being able to load onto, and run properly with the real-time system, I have found a couple systems that look good.
I have 4 systems here running various versions of EMC2. 3 are Dell Optiplex systems, the other is a Gateway Profile 3. The Optiplex is Dell's commercial-grade desktop system. They generally have Pentium CPUs. I have used 600 MHz CPUs with servo interface boards, you need more speed for the software step generation. You need 256 MB of main memory. Some of these Optiplex systems have a video memory card on the MB separate from the system memory, and work fine. Some others do not have that feature, and you may need a plug-in video board with at least 4 MB of memory for Ubuntu to properly configure and install without playing games. The on motherboard video chips that share system memory can affect real time performance. The Gateway Profile 3 is a closed system, basically the same works as a laptop in a pedestal housing, with separate keyboard. These are great for fitting inside big pendants. It does have parallel and serial ports, USB, cardbus (PC Card) and Ethernet. It seems to work quite well with EMC2. The version of Ubuntu shouldn't make that much difference, unless you are using some cutting-edge hardware. In any case, the version 8.04 would be the best choice, as it is newer.
