Much depends on how the tank will be used and part of that is your understanding what a filter does, so that you can make better decisions on what you are more likely to need. We often get to involved with using the designs filter folks put out but they don't know what we might do either, so it fits better if WE make that decision.
Most of us get the idea of mechanical and "straining" the debris out of the water so it is hidden in the filter where we clean it out and we don't see it! Bio is a bit harder to figure as how much bio filter media we need and depends on what fish, home many and what type and size as well as how much water we change. Even how long the tank has been up changes how much bacteria is in the filter versus all over everything else like walls, plants, etc.
An old tank with lots of slick feeling on almost all surfaces means we don't really need to pack a filter with good stuff for bacteria to grow on as it's already all over things!
Chemical like charcoal? Most of us lay it back as too messy and too not needed!
An 8 inch pleco may need a big mechanical just to clear his "dailly deposit" while a half dozen neon tetra and lots of plants may just need something really easy to swish out once in a while!
So look it over and decide, do you need lots of straining for debris or lots more of converting ammonia/ nitrite? A filter box of that sort leaves lots of options so I would likely keep it.
