There's a plethora of different bare metal / dedicated server hosting providers, so recommending one is like recommending what type of car you should buy. The most important criteria generally involve: location, managed vs unmanaged, quality vs price, class of hardware, network uptime and hardware replacement SLA, number of servers, smaller or larger provider

The best resource to research different providers are the webhostingtalk.com forums. You can also contact me and I will do my best to advise you based on your desired criteria.
