Gaming PC for Grandsons - Suggestions appreciated

[RickAnderson]

My grandsons (ages 10 and 14) are visiting this summer and to alleviate the constant "He's been on the computer longer than I have" refrain, I decided that we would build a second computer.
Parameters:
1) I would like to do this for under $800.
2) I have a monitor, mouse, keyboard, speakers and don't require a sound card (onboard is sufficient).
3) It must be capable of playing Battlefield 2 (hehe - I plan on kicking some tail Muhahahahahaha).
4) I am planning on upgrading the CPU and possibly adding another video card in the future (once the FX CPUs come down in price).

Here is what I have picked out so far. I know I am missing a Power Supply and just took a guess at a satisfactory case (any suggestions would be appreciated). I saw an Ultra XConnect 2 power supply in my local PC hardware store and was impressed with its modular cabling.

Mobo: ASUS A8N-SLI Deluxe Socket 939 NVIDIA nForce4 SLI ATX AMD
CPU: AMD Athlon 64 3500+ ClawHammer 2000MHz HT Socket 939 Processor Model ADA3500ASBOX
Video Card: XFX PVT42EUDE3 Geforce 6800 XTreme 256MB GDDR3 PCI Express x16
Memory: Crucial Technology 1GB 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered System Memory Model CT12864Z40B
CD/DVD: PLEXTOR 16X DVD±R DVD Burner Black IDE Model PX-740A/SW-BL - Retail
Case: COOLER MASTER Centurion 532 RC-532-SKN1 Black Aluminum bezel, SECC chassis ATX Mid Tower

Any suggestions would be appreciated
Thanks

Welcome to PCMech.

What you have so far is good. I would skip the Ultra power supply and put in something like the Antec TruePower II 550w.

Don't forget Windows XP.

Battlefield 2 thrives on RAM, if you can spend a little extra, 2GB would be a good addition.

One other question - Does the CPU come with a fan or do I need to buy one? If so, any suggestions?

Thanks

The CPU wil come with a heatsink and fan if you buy the "Retail" chip. If it says OEM its just the chip.
