Welcome! AIO units definetly look slicker but you can also set up your own with higher end components for the same price. Can't go wrong either way though, you'll enjoy both! You can also look at getting a small tank custom made with overflows to a sump for a good price. Keep researching and I'm sure you'll come up with right system for you.
