@Burpo and @surfin - here are 8 Xeon X5675 for $100 each, and there are a bunch more around $120. Seems like a decent deal right?

For me, the chips are not the thing. My X5690 was $350 nzd landed which is ok.
In NZ the motherboards are just not available, so I have to get them from the states or wherever. With current exchange rate and freight they're more expensive than new mobos. Probably $500 landed for a rampage which is what I really want. Or even a gene to play with small form factors.
That site I mentioned before and got in trouble over, sorry! has cheaper mobos than ebay and loads of them, so maybe worth a look for me anyway.
