As we figured it out, the new tank will hold about 150l which is about 42 gallons.  this means enough space for 4 fishies. 
We got it for AU$ 100.-- including stand, hood, huge UGfilter, heater, airpump, thermometer.

It needs a bit of work done though.
Cleaning out with vinegar, this is a natural cleaner, disinfects too, will get rid of calcium marks on the glass.
The gravel I will put in my plant pots as it is too hard to clean, it sure will provide some nutrients for the plants with all the fish poo stuff on it.
The metal needs a bit a polish, not much.
The bottom of the stand wants to be replaced as it walked. Try to get a thicker piece of wood. Then sand it down and respray with chocolate brown. It is black at the moment.
The hood needs a bit repairing too, as there is no glass top. Need to get one...

The setup plans are the following:
Nice background picture, as it will stand at the wall.
As Hump and Hep digg plants out, we are thinking to get some fake ones for the background.
Driftwood with real plants and the teracotta pot with the dwarf anubias at the front. Maybe an "old ship ornament" or sth like that too.

We also want to get an additional internal filter, an airstone about 20 inch long.

Basically what do you guyz think about having fake AND real plants mixed?

 WHERE'S THE PICTURE!!!!!!HMMMPH!  I thought you posted a picture!
With all that typing you could have had that whole tank set by now and a picture too boot! LOL
Hurry up!
What's taking so long!

OK, OK girls, lol
first a few pics before cleaning and original stand, LOL... went out to investigate for a light, discovered the lady used a normal 1 ft kitchen UV light, was rusted anyway, we chucked it out.

I started to clean the tank with rocksalt, scrape the algae off 

And here a few pics after a rough cleaning, still needs fine work done, but we should be right in a weeks time to have the stand fixed and resprayed.
Then I can start to landscape. We like to put a "deep sea" image at the back. And fake plants.
The life plants and deco at the front.

Ahhh btw, bought some deco hinges for the hood flap and a nice knob 

lol it looks awesome!!! XD I cant wait to see it all set up! Hurry up Hanna lol just kidding XD

lol we should all get a pic of us by our fish XD

Minde only one pic, I dont think we need a hundred pics of you by your various fish XD lol

thats gonna suck, trying to find a light. im so used to starter kits where they light was included

good luck!!!

yeaaahhh we'll find a light, sure there is sth out there to fit in...

Andrea, the 34 l tank we'll use for a few neon tetras, maybe about 10 really colorful ones 

It looks like you're doing a great job. I can't wait to see the finished project. I remember having one of those metal edged tanks in our grade school classroom. Sometimes I wonder if they were a better idea after all; I cut my finger terribly on the side of one of our regular glass tanks while cleaning it. That was probably over 20 years ago and I still have the scar and no feeling on the side of that finger!

Yubonne, welcome to the forum 
We cannot wait either to have all ready. Unfortunately the most work can be done only on the weekends.
I also want to seal it again, just in case there may be a leak. It is the opportunity now while it is empty.
The metal edges are not sharp, they are ok. Already cleaned them  they look already much better without stains.

Thanks Kat, yeahhh the old chook is fine 

Will do, lol 

no its just a really old aquarium. this is before they thought of glass welding or whatever. It doesnt interfere with viewing, as I believe only the corners are reinforced with metal, am I right Hanna?

AW YEA! thats epic! lol or watching the aquarium channel on the tv.... lololololololol

mmmmmmmmmmmmm shining and sparkling...
