Best Forum Software With Low Server Requirements?

[Vec&sec]

Hi, I don't have a big budget for hosting right now.
Is there any forum software that works well with low RAM and limited disk space?
I'm just starting out and expect slow growth at first.
Can I rely on hostingsource.com dedicated hosting solutions? What specs should I look for?
