Up and running :)
I made the bracket out of some spare acrylic, just pieces glued together and fits snugly over the rim at the correct height, the white piece of plastic is some sort of a furniture bracket from IKEA I had laying around.
Drilled it to take the return hose, ended up quite neat.
The bucket is from Big W on special for $8, holds 12L and should do me for about a week/week and a half.
I'll tidy up the wiring at the back after the unit has been running a few days so I make sure there are no bugs in the system.
Thanks for all your effort
firechild - much appreciated. :)
