Need advice on gaming PC

Hi to all, i'm new to the forums, so sorry if i did not respected any rule (if that happened please tell me)....

I am trying to upgrade my old PC, but i am in doubt if i should buy a new ATX tower or my old one does the job;

AND

I am not sure in certain hardware parts, because of the global price (something like 1000.00€ ~ 1400.00$), so i am asking for your opinion.

This PC is intended to PLAY "HEAVY" GAMES, ex: I am waiting for a game to be released that is called "Storm of war" (i it will be released maybe next year - 2010), but there is no system specs yet, so i am trying to get a PC that runs Flight Simulator X smooth with great graphic quality (if it runs this game, it´s probable it will run the other one).

I would also like a PC that consumes the fewer energy possible and does not make to much noise, but these are last considerations, don't concentrate your opinions on these...

_______________
The new parts are:

POWER SUPPLY:
--- CORSAIR HX-1000W
--- or another you think its better in quality/price

CPU:
--- Intel Core I7 920 (2.66GHZ)
--- Intel Core I7 950 (3.06GHZ)

MOTHERBOARD:
--- Asus P6T
--- i trust Asus motherboards, but any other sugestion is welcome

GRAPHIC CARD:
--- ASUS GTX295 1792MB DDR3 PCI-E

MEMORY:
--- KINGSTON DDR3 HyperX 3GB 1600Mhz
--- not sure if it's worth buy HyperX memory or "normal" ones

The parts that i will use from my old PC:

TOWER:
--- Here are some pictures of the tower with no equipment in it:

Description of the main photo:
- from the top left to the right, there is space for 4 optial drives, next, space for 3 hard drives, next, space for a fan (or 3 hard drives), next, space for a fan...

- from bottom left to the right, there is space for the power supply, next, space for the motherboad and its outputs (above the motherboard, just next to the power supply, it has 2 entrance for air circulation)...

- you can view other pictures of diferent angles on the left side of the picture.


--- If it's better to buy a new one, especially because of the air circulation, shoot up a good tower (quality/price)

HARD DRIVE:
---

MONITOR, KEYBOARD, MOUSE:
--- no need to tell what i have, but the monitor i will buy one a bit later when i have enough money (to use HD)

SOUND CARD:
--- Sound blaster Audigy 2

NOTE: I live in Europe, i'm telling you this because there are certain hardware parts that are only sold in the US....
