Over flow box or hob filter

[Charlie brown]

What up reef fam just wanna get some opinions I have a 14 gallon nano that I put together 1 clown, 1 purple goby, 2 purple urchins, 1 banded shrimp, 2 frags ginoapora, 1 mystic Monti and 1 coral I forgot the name and so far is been doing pretty good was able to get it going for around 150. Now I put together this tank just as simply as I could cause that was my plan the only thing I'm second guessing is my filtration I have plenty of live rock, I'd say around 12 lbs of it and I thought just a hob filter would be just a boost to polish the water and run carbon when I needed to. Now that I've added way more coral I'm kinda thinking I should of went with the inside the tank over flow box. What you guys think

Overflow box is only the first part of the connection to the sump, any commercially made are really big, check their dimensions.

HOB with sufficient flow and space in it for a custom filter media is less obtrusive, being behind the tank.
