I tried the rs1000, it performed well and could always hammer the CPU without any issues. Saying that, I've hammered the vCPU's on the vserver range and not heard a peep from them and performance continued to be great.Would you recommend that over the RS1000 then?
What do you use it for?
Netcup provide a very good service, just make sure you understand how their billing works to prevent frustration when you come to cancelling.
I use my box for downloading and as a remote desktop, it's also running Plex.
