The Sun Ultra Enterprise 2 I ordered on eBay arrived yesterday, 2 days after it was shipped - amazing! Unfortunately the box seems to hang at the beginning of the memory count. I suspect the problem is the RAM configuration. I read somewhere that the minimum RAM configuration would be 128MB of RAM because the RAM is installed 4 DIMMs at a time, with 32MB RAM the minumum (4x32MB=128MB). My machine has 8 sticks of RAM, but shows 64MB at the top. I won't speculate beyond this, but I may have some other RAM coming.
My machine has a single 200MHz UltraSparc processor. It's possible that it might take up to a 400MHz processor, but even if it doesn't, the machine is still dual processor capable. I was amazed at the internals of this machine, everything is packed pretty tighly. I couldn't even see a spot I might stick a hard drive other than under the floppy bay. The Ultra 2 is a heavy beast! I'm somewhat surprised I only paid $14US for shipping, considering how fast the machine arrived, its packing, and weight.
