Hetzner also has options for Xeons and Dell PowerEdge servers for a bit more a month, but I've also had great experience with their best value hosting servers, ran a site on it for a couple of years without running into any h/w issues before moving to AWS due to its easy managed RDS, S3, SES services. But if I'd just needed a single dedicated server with great specs I'd use Hetzner in a heartbeat.
