thats perfect two loops or one?
couple rad questions

For fans, I would look at the 1850RPM Scythe GTs, if you can ever find them in stock. Review here.
OK, so lets say 300W for each GTX480, 130W for the i7 gives 1030W. Bump that up to a nice round 1100W for some OC headroom and that is what you will be trying to dissipate at load.
Looking at Skinnee's results for the RX360:

We can see that even with high speed fans, the 360 will only just shift our heat load with a 15C delta (not great). So we have to go for a bigger rad, but then we knew that already.
So, for an RX480 rad we take the 1100W and multiply by 3/4, this gives 825W. Looking at the table, 1800RPM fans can shift that with a delta of 15C. Better but still not great.
Now an RX480 and an RX240, take the 1100W and multiply by 3/6 (or 1/2), this gives 550W. Look at the table again, now your 1800RPM fans shift it with a 10C delta. Much better (same result as running 2 RX360s), and good performance.
For overkill, an RX480 and an RX360, multiply 1100W by 3/7, gives 471W. Now 1400RPM fans can shift the heat with a 10c delta, 1800RPM fans can manage roughly an 8C delta. Great performance.
You can go push pull for roughly a 30% performance boost (makes a single 480 viable with a 10C delta and a 480 - 360 combo a monster with a ~6C Delta), or add shrouds for roughly a 6% performance boost. Details here.
Edit: And as Nick said, loop order doesn't matter other than res>pump. Water temperature rise is so small that it is far better to set the loop up in a way to give you the cleanest lines, least restriction and best flow.

3x 480's = 750w TDP, 980x = 130w TDP, x58=24w TDP. Your loop needs to cool 1004w at max load non OC'd.

The 360 at 15c delta, med. fans cools 860w a 480 is about 1/3rd more or 1143w of cooling. So with the 480 + 360 you are at 2003w of cooling or double your non-OC'd load. If you OC your at about 1200w or well below what those two rads can do. If you swap that 480 for a 240 you get about 580w of cooling for a total of 1440w, again well over your needs.

It will perform reasonably:
1100 * 3/5 = 660
@ 1800RPM you get a delta between 10 and 15
See if you can follow this:
(660 - 575.15)/(862.73-575.15) = 0.295
0.295 * (15-10) = 1.475
10+1.475 = 11.475
So a Delta of 11.5C
Average performance.
Yes OK, so it is badly laid out and not explained. Doesn't matter.

Ive seen the 360 rad at the bottom more than once on other fourms and if they did it im sure I could. Im going to mod the top for a 480 rad. Im going to have my fans blowing cool air from the outside into the case and a fan blowing out the back hot air.

See the 360 rad at the bottom? Its sure tight but it fits
