first time doing a water cooling loop

[xdeathshot20]

so i just ordered the parts for my new water cooling loop for my pc.  The specs are right below.  I got a 280mm rad for the front, 240mm rad for the top, cpu and gpu blocks and of course everything else that is needed.  so my issue is this is the first time doing a water cooling loop and i dont wana mess it up. i am using soft tubing for this build.  the pump/res will be mounted to the front rad on the top fan using a bracket.  my questions are basically, how should i do the runs and how should i set up all the fans.  all the fans that are in my system will be corsair ml pro.  fan size will be determined by the radiator.  the only fan that i have thats not on a rad is a 120mm (i believe its a 120mm i could be wrong) in the back as an exhaust.  i also want to have a drain port for easy maintenance when needed.   so if you guys could help me that would be great.

get your blocks, radsand pump, and res in. then you will be able to visualize how you want you tubing to run

Front fans should be intake and the other 3 should be exhaust. The loop order wont matter. Like stated, get everything in and just plan it based on looks or based on the ease of draining it. That will also tell you if you need any special fittings unless you bought some already, along with the drain valve.
