Ask HN: Best value/price dedicated servers in US and Europe?

We've video/image processing apps and need powerful hardware with uptime guarantees. Dedicated servers are the most cost effective, no virtual or Amazon SWS. What do you use? Currently we have servers that cost around 100$/mo for a Xeon 1270 with 16gb ram, but the uptime is not that great, downtimes are frequent. We know plenty of more expensive solutions (for instance for metadata & cdn we use Softlayer which is expensive and more reliable), but we need cheaper options. thanks!
