I've had two different boxes through seedit4me. They're pretty decent. I really like the app selection and the dashboard overall. I sort of have mixed reviews about their performance.
The first box memory would instantly max out (@2GB) with only one client running and no additional apps installed by me. The box would bog down and became completely unusable. I contacted support and they told me to switch torrent clients to a lower performing one. That marginally fixed the problem and wasn't idea. The box would still get bogged down regularly and needed lots of restarts. It seemed like the machine was suffering from a memory leak. The second box was more or less the same configuration spec wise but it was unmetered. This time around, I ran the torrent client that I wanted and it ran flawlessly. The memory usage never exceeded +/-30%. So I'm not sure why I couldn't run that client the first time.
Lastly, the 'Fair Use Policy' is a bit of a grey area and it's stated that the server dictates the values based on usage. For me on the unmetered account. The box was heavily throttled at around the 6TB upload mark. You could still download at around +/1GB speeds but you literally had zero upload ability. That's a little disappointing for an 'unmetered' box.
