First time PC Case grow advice needed! Black Jack Auto fem x2

First time poster, have been reading a lot about cultivation and have finally ordered my seeds. My plan is as follows

Full Tower ATX PC Case, spraypainted flat white (mylar alternative)
Two 120mm intake/exhaust fans. Intake at front bottom exhaust rear top. Exhaust fan equipped with homemade carbon filer (activated carbon)
Space limits me to CFL's, looking to purchase up to 15k lumens either using two higher wattage or 5+ lower wattage CFL bulbs. Will run 20/4 from germ to harvest
Will run a mixture of 6500k spectrum during veg and switch over to 2700k during bloom.
Will be using a quality soil brand without nutrition and will feed with quality nutes in appropriate doses. Will provide appropriate quantities of p, n based on cycle.
Homemade SCROG net to maximize yields from 2 plants.

I have a few questions for anyone who's willing to help.

My first concern is airflow, I own two yate loons that move about 100 cfm ea - is that too much cfm to produce a favorable environment for my plants? Also, will a homemade activated carbon filter covering the exhaust 120mm reduce the air out-take enough to create an imbalance in airflow ?

For two plants in a 22"(h)x9"(w)x22"(d) computer case, is 15k lumens appropriate ?

During the initial 2-3 week veg period, will the plant be able to cover most of the scrog net? Because these are auto's their life is finite and I want to make the most out of them before its time to harvest. Will I be needing to continue training the plant into bloom or is my window of opportunity limited to the auto's veg period?

Lastly, what is an appropriate ph of chlorine-evaporated tap water to feed my plants?

I thank you all for your time and look forward to growing with the community!

yes, that will throw off your airflow a bit...try a stronger exhaust and weaker intake...
you could do well with a 150w hps in there, but ive done pretty well with micro cfl'ing. get as much light as you can in there...
try and get as much of your training done as early as possible...you want your girls using all available energy for flower production...
depending on medium, i try and keep my ph between 5.8 -6.5...
...happy growing!

thanks for the response! I will indeed look into that fan solution.

I've been looking at ballasts to support an hps system. It's difficult finding a retailer that ships to canada with affordable ballasts and proper spectrum hps bulbs (2700 for veg 6400 for flower)

The only place I've found has lowest 250w ballasts for around 140, 400w is 170 and the bulbs are only about 30+ each - they do however produce around 30-50k lumens so damn ><

any suggestions as where to buy / what hps setup is best for a pc case? the ballast needs to fit and the light needs to mount properly.

- I've been looking for a 3x3x3 grow tent, or something just slightly larger than a pc thats easy to work with. If you guys know of anything better let me know

Yeah what you want is a MH or HPS, preferably 250 since you aren't using mylar, but the scrog will make up for that. Here is a link to a cheap 250W make sure you get the 6" cool tube reflector so it will fit inside the pc case. It also comes with a free warranty, lol.(Edit- you might want to not buy their bulb because it is probably shitty, so just get a nice 250W MH bulb[ http://www.hydrofarm.com/product.php?itemid=1506 ] and a nice 250W hps bulb [ http://www.hydrofarm.com/product.php?itemid=7789 ] these will give much better results and lost alot longer than the shitty ass bulb you will get. )
