some help with a dishwasher setup

Hi guys, forgive any stupid questions I'm a complete noob at this, I can grow penicillin in a coffee cup but that's about the extent of my growing experience.

I've done a fair bit of reading / planning and liked the look of some of the fridge conversions zone people have done, then just yesterday my dishwasher gave up the ghost. voila! We have our growbox.

Internal dimensions are 21"wide x 20"deep x 24"high

So I'm looking for some advice

1. Is this enough space?
Its roughly the same size as a fridge so I figured it would be.

2. Strain / number of plants
If someone could give me an idea of which strains would do well in this limited space

3. Lights.
I was thinking 250watt cfl should light it up ok, Hung on a chain to raise / lower

4. Ventilation.
Once I've stripped all unnecessary parts, two holes in the floor, there will be a small space under the floor of the growbox where pump and motor used to be. Then cut a hole in the back, at the top to mount a large pc fan to blow out.

5. Odour.
Any ideas on how to combat smell.

Think I've covered everything I wanted to ask if I've missed anything please let me know.

I'll post some pics once I get started

Thanks
