I usually just buy supermicro rackmounts with intel cpus. I've been doing this since the early daya of xen on netbsd ( the 1990s ), and have had no issues with hardware compatability worth remembering. 10G copper ethernet, etc... usually just work. The only thing I've had no luck with are the embedded LSI raid chips, but I usually install an LSI 9260 anyway. ( the current state of that support may have changed since I last looked ) 

Your mileage may vary. 

Compared to old hardware, even a basic, low cost, supermicro 1U will be a welcome upgrade. YOu can do a lot with $2000 USD these days.
