Sun Microsystems' Ultra Enterprise 10000. A supposedly bad-ass machine capable of 64 processors, costing around $5 Million. I hate this machine because of its nonstandard cabinet sizes. It is shaped like a big amorphous blob, so you can't put it in a line with your other unix machines, you have to seperate it from the others, so it can scream, "look at me!! I'm big and expensive!!"
