Help with Brother's Grad. gift computer

[Exsequor]

Hello all...new here, so I'll apologize first and foremost. My brother's graduating soon, and I want to get this out to him. The following is a list of components I put together on the extreme pc website for him, only I'm not that computer savvy. I have a few major questions.

1) will the standard fans that come with the chasis be enough for my cooling needs...if not what would you suggest?
2) are all the components compatable?
3) is this a good basic set-up that will allow him to upgrade? Worried about the motherboard
4) am I really that dumb? don't know if I'm buying a porsche and putting a focus engine in it...or a Hummer suspension.

Please let me know if I should focus more on something else, possible solutions to problems, any advice, or if it looks OK to you.
Again, I'm sorry for the bother. It's just that I've spent about 2 hours combing this site. And although I have a far better knowledge now, I know enough that I need help here...

CPU= AMD Phenom II x4 940 Black Box Edition-3GHz, 8 MB cache-quad - socket AM2+ (45nm)

Mother= Asus M3A79-T Deluxe AMD 790FX CrossFireX AM2+ Quad PCI-E 2.0 (1066 DDR2) 7.1 audio 140 W CPU support

RAM= 3x2048MB OCZ DDR3 PC3-15000 (1866MHz) Triple Chanel Reaper HPC

Case= NZXT Zero Aluminum (no PS) has front 1x120mm fan; rear 2x120 fan, side 4x120 fan top 1x80

Power= OCZ 610W PC Power Colling silencer 610 (SLI/Crossfire)

CPU cooler= AMD AthlonX2 64 Retail CPU cooler

Round IDE HD cable= Thermaltake 50cm UV reactive SATA cable

Hard DR= Seagate 500GB (7200) 32MB cache Barracuda 7200.11 NCQ SATA2

Optical DR= LG S-ATA GGC-H20L Blu-Ray

I/O Controller= ON board SATA, RAID0, RAID1 controller

GPU= Sapphire ATI HD4870x2 750MHz core (2GB 3600MHZ DDR5)

APU= Realtek ALC1200 7.1 High Def. Auio

Network Card= On-Board 10/100/1000 Gigabit Integrated Network Card

OS= Vista Home Premium 64--bit
Ok, so that took a while. is there something here that's not like the others? Can the motherboard handle this? Should I add somekind of thermal meter? Any feedback would be appreciated...I'm thinking of building my own as well (mine's like 7 years old), but I promise I'll wade through the thousands of threads to get a better idea if I do.

You do not need any extra cables - the motherboard comes with 3 SATA data cables. I recommend a Western Digital Black instead of that Seagate - Seagate is having massive problems right now.

WRONG RAM. That's a DDR2 board, not DDR3.

Oops...I had been looking at some asus boards that would support DDR3, but couldn't find it on site and forgot...sooo

These are the new specs, ***going to remove these cables...I changed HDD (thanks for the heads up) and RAM...will motherboard support this? or do I need to change it to 2x1024MB?

My sister is chipping in 500, and my parents are doing the same, so I'm trying to stay under 1,700. Will he be able to upgrade this enough? Am worried that DDR3 will be the new wave and DDR2 outdated in 2-5 years.
Thanks again GLC

I'm a bit confused - how much ram do you want?

oops, disregard this.
