anyone else have 2x4x7 set-up

Pretty much have on paper what I need to start. Already have tent,400 watt air-cooled light and a pretty good idea about ventilation. I'm begging here to see if someone would like to share their knowledge on how they set-up their's, such as fan placement,light,exhaust fan,etc. Did you and can you place any of this on the outside so as to save space. How many plants did you have in there comfortable. My first indoor grow and really want to get this baby off in the right direction. Good/bad/drop dead comments are appreciated. Thanks..........................

What you should do is do a dry run with your tent and light so you can see how hot it gets and adust as needed. I have my fan suck from the lights and filter. Here's a diagram and some pics.
