wanting to down size MUST LOOK sick deal!!!!

i currently have a 90g tank with cornerover flow oceanrunner pump 69g sump, protien skimmer, sundial 4x54w t5 with built in timers custom stand with insane power bar.
looking to trade that for a self sustained bio, nano or something in the 28-40g range. i am willing to trade straight up and cut my losses also what ever lifestock that doesnt fit you can have.

The stand comes with wooden pannels as well so you dont see all the internals
