Semi Pro studio set up (what equipment do you need?)

[DIGITAL SCREAMS]

Guys I was just wondering whether we could list the necessary equipment that is fundementally needed in order to make decent sounding tracks. You dont have to list specific makes and models (this might just confuse the issue at this stage)....nope....this is more of a sort of run down for people like me - a noobi producer who wants to get a general overview of what is needed. I'll start this list off....and perhaps you guys could add to it:

DAW

Computer (Audio PC, PC or MAC)
Audio sequencing software (Cubase etc)
Audio + midi interface (soundcard)

Mixers

General purpose analog or digital mixer

Speakers

Dedicated monitor speakers

Instruments

Synths, drums, guitars etc

Outboard

Please continue list.....
