What is the easiest way to make a really good storage in ATM 10 lite ?

Im having some problems with inventory and i was thinking about AE2 to build a storage but its really hard to understand cus im a beginner i also was thinking about mekanism storage but needs pollonium so its really hard too. Is there any available mod on the modpack that can help me with that? Im used to use refined storage but its not on the list
