Most minimum VPS RAM is now 1GB. You can run SER with this, along with CB pretty well. Number of threads may need to be tuned to between 50 and 100 though, depending your CPU bandwidth and speed. This should be fine for several concurrent projects.
I have 4gb with 300 threads, tons of projects but only running 10 at a time on schedule - That pushes my VPS to the limit tbh. So for 240 threads you would probably need 2 gb or better 4 gb i would suggest.

easily achieves 1,000 threads
I run it around 400 threads during the day as I am working on it and 1,000 threads over night.
My older machine ran it at around 200 - 250 threads, it only had 4gb ram. intel core2duo E8500
