New to water cooling need help

[MUZZL3FLASH]

Hi i am 15 years old and are new to these forums so forgive me if i am doing things completely wrong.
i am thinking of making a water cooling rig in about three months when i get a job. I have already found some parts online and would like your opinions on whether this is a good setup or a complete failure either way nothing has been bought yet so changes can be made the setup will be as follows:

computer components:
corsair 800D
gigabyte ga-x58a-ud3r
intel i7 930
Visiontek 900322 Radeon HD 5870 (possible duals havent even decided on graphics card just yet)
4gb ddr3 for RAM

water cooling setup:

Swiftech Apogee LP High Performance CPU Waterblock - Sockets 775/1156/1366

Swiftech MCP655-B 12v

XSPC RX360 Triple 120mm Radiator

XSPC Dual 5.25" Bay Reservoir

EK Gigabyte X58 Northbridge / Southbridge / Mosfet Liquid Cooling Blocks - (EK-FB KIT GA X58)
(http://www.frozencpu.com/products/90...tml?tl=g30c293)

Feser Xtender 120mm Radiator Shroud - Dual Green LED

Delta 120 x 38mm High-Speed Fan - 190.48 CFM (AFB1212SHE-CF00) (possibly)

plus water blocks for the graphics cards above

sorry if the way i have set things out is hard to under stand this is my first time making a post so feel free to tell me i am bad at it or how to improve that also goes for my system

Do you have the actual computer built and running yet? If not worry about getting the computer working well then think about buying water cooling gear.

That system shouldn't really need water cooling. Surely at 15 you have better things to spend money on than water cooling gear. Are you not still in school? Working and school?

i currently have the gigabyte board the processor 2gb ddr3 and a graphics card (not sure what type) that is about 512mb this is allready running but i would like to update my graphics card

the reason i am asking this is because at the moment i have these parts in a low airflow case that cant really be improved on and my computer keeps shutting down because the north bridge is over heating what i am planing on doing is buying the corsair 800d and if that provides enough cooling then i will not bother with water cooling if i still need more cooling then when i get a job i will save up my money and start getting the parts but that was not the idea of the post the main idea was to ask if this was a good system i just want opinions no water cooling parts have been bought yet so i want to know if this would work should it be needed.

P.S computing gear isn't the only thing i spend my money on and i am still in school but am i am all the top classes so the work is easy for me i always put my schooling first and exams are a few months away.
