comment Mail server hammering
I think you're on a completely wrong track here. You should not have an open SMTP relay at all. If you have one, it will be abused, it will end up on black lists and your clients emails won't get through. Start requiring authentication for sending email, the botnet will go away after a while and you won't be part of the spam problem any more.

comment Can I mix and match rack mount servers?
There are plenty of examples of name brand rails and racks not fitting each other. In the end, if all else fails, you can buy a shelf and put the server on top of it. Not clean and eats up space unnecessarily, but as long as the doors close it's usually good enough.

comment How can I optimize nginx? From benchmarking it seems Apache2 is faster for static delivery
Well, if you get a 100k hits a day, every request takes three seconds to serve and they are distributed evenly throughout the day, you'll have 10+X apache processes running with mpm-prefork, where X is you MinSpareServers setting. You'll have plenty of safety margin, so there's not much to optimize.

Actually Xen is part of Citrix, and I'd say VMWare's products are quite solid nowadays.
