Pretty much as stated. Logic carrier (IP29+PCI slots in the easy-to-insert unit with a handle) equipped with 512MB RAM and 2x180MHz R10ks.
Also available - Sun-4/300 series boards. Fully loaded with memory and a 192MB memory expansion board. Also has CG5 framebuffer. The case is essentially nonexistant, but it does come with the VME cardcage, power supply and user configurable fans for cooling! You don't need to take the cardcage if you want it shipped.
