Hi Steelwool - Welcome to AFN 
I see the guys are getting you all setup and having an incredibly similar sized setup, i thought it may be usefull to add some input.
I've used CFL, HPS and LED in my 60cm x 60cm cab, the HPS gave me the most trouble (Although i didn't have a cool tube setup), and i found LEDs to be the easiest way of getting the best yeilds from my cab.
you can get a sylvania Grolux extended blue spectrum flowering bulb if you're set on HPS - they're about £20 each and lasted me a couple of grows (although some people use them for ages longer)
If you don't live in a cold place, i would consider LED as a good option.
Space wise, I like to have a 10 litre and 6 litre pot in my space. I like 2 just incase one turns out bad. (i doesnt happen often) ^_^ Then there's just room for a movemant fan and a small tube heater.
I'm not sure if anyone mentioned a Temp and Humidity gauage. It's quite important to keep lights on temps to around 75-85f
Just throwing my 2 cents in
all the best
