Back to Helping Morcs,
It all about stability, the more water you have, the more stable your tank going to be.
In lieu of volume, you're going to have to put a heap more time and effort into it in terms of W/C's (like, daily) especially 'till your tank ages out properly. Also temperature fluctuations are going to be bigger.
Not to put you off, but ideally, if you want a nice nano that is not going to take all your time and effort, get a nano size display and have a sump on it to increase over all volume.
All your gear is neatly hidden away, You don't have to over-stress W/C's etc, and you'll have a better environment for your shrimp...
Just my opinion, but I do not like the "All in one" type tanks, not least since they tend to charge like a wounded bull for consumables and replacement parts. Also tends to work out cheaper doing it in components, and not a big initial out-lay.
