If a bar fridge is too bulky for the room , have a fold up Esky with handle & wheels in there for those neccesary fluids .
The Esky can be put back into the garage when not in use.

Plug in duel speaker radio that works when near a computer set up. (many radios get affected by computers) $10 at garage sales

ADSL connection.

Phone + Mobile

Australian made comfort chair (these are usually much better made & dont rattle to pieces like many imports).
Can be bought from 2nd hand office furniture dealers for less than half of new price.

Small TV with good sound, preferably duel speakers for sound quality, otherwise one will find themselves having to put the volumn up too high just to get some sort of sound definition. Cost New $120

A box with lid for the stray paper work.

A good size monitor to save unnessary eye strain.

UBS power surge protector to save your gear from being blown up & your files & programs from being wiped especially if one lives in QLD.
Make sure one plugs their Modem into it as well.
Quality units cost approx $150
Smaller systems are good for one or two electrical strikes & should be replaced after that.

Have a computer that has a backup hard drive for storing those important programs & files , approx 30MB is more than enough.

Cheers.
