I have found that a lot of the audio editing software you can get away with quite low specs. I record my podcasts on a 8 year old laptop running Windows XP. It rarely connects to the internet and I record to a thumb drive that is backed up so there is nothing to lose on it. In this particular case something similar might be the best option. For pod-casting anything over 2 or 3 ms in my headphones throws me off my game.
