This is just like the everyday air conditioner that we use. The only thing unique about this that the cooling unit has no moving parts. The only movin...
This page shows you the things that you need that you need to buid this machine.
Put epoxy on both sides of the peltier module and connect the heat sinks together. Note: Copper paste would be better.
Put epoxy on the heat sinks and connect the two PC fans to the heat sinks.
Attach the wood with epoxy.
Use the tube for better ventilation.

You can use a Computer SMPS, there is absolutely no problem with that. Go ahead. (y)
mr. clean. Power supplies supply power. They are like a source. Devices pull what they need from it. so 14 A module will only pull 14 A from power supply :)
how big is this unit...once it's built? how portable is it?
your power supply indeed has a to low current. the reason its blinking is becous it shuts down do to the lack of power / starts up for a second and then shuts down again ( this is the easiest way to say it its actually more complex) thats why your fans are twitching. if you wire it in series the current is to low for your peltier do to the fans that requir less current.
It is fun to read comments from some of the users. No offence but many don't know about peltier at all. I have been playing with them for past 2 months. They catch your attention when you see them at work. First of all, do not connect peltier with a battery. It will overheat and fry. Attach a heatsink or someother mechanism like water flow to keep its hot side cold.Which one is hot side and which one is cold?The side with text written is usually the side that gets cold when current is applied.I am in China and its super easy to buy them. You will not be able to get them from local stores, try online shopping websites.All peltiers can create electricity as well if you create temperature difference between its both sides. Warm its warm side while keep cold cold.To start with them by the TEC-12706 its should be dead cheap like under 5$
I hace recently purchased TEC1 12706. Provided power input to it from a 300 W SMPS. Volatge 12 V. Room temperature was ~35 degree . Heat sink and fan applied on hotter side that of CPU hitsink and fan . When I tried to measure the DC current ... using clamlmeter it showed reading to be nearly 1.6 A for peltier . I think it should consume 6 A why it is consuming less current.
a few notes, a radiator with water on hot side would be great addition. as your design is you are blowing both hot and cold air into a room (I admit they are blowing in different directions though) with a water setup on the back you could take the heat outside and let the air blow on it to cool it down. the addition of several items like a pump will be required.
also using 2 or 3 peltiers piggy backed will be better than 1
and last but not least is you may encounter an icing issue.
