Dual CPU will be hard for that budget.
I suggest looking into quad cores with HT enabled like the X3440 or the new E3-12xx CPU's.

Is this for a VPS node? I can't see many providers being willing to provide that many ips unless it's for a VPS node.
Also, for the bandwidth, I see 100mbps. Is that the required port speed, or do you need it to be unmtered? You're going to have a hard time finding a 16gb ram server with 100 meg unmetered and 32+ ip addresses within your budget, but if you only need 2,000gb / mo, or maybe a bit more, then you should be able to find what you're looking for from a number of providers, depending on what disks you're looking for as well.
Looks like I did miss the BIG window that calculates a running total - what was the price on your custom build?
And I missed that he said he looked at it, I thought that said burst.net in the first place haha. I fail.
You could also look at SecuredServers.com - but I think DataShack has the most competitive pricing. Probably the best you'll find.
