Building new system, need some advice

Im working on building a new system, i have some ideas on what to use but need a little more advice. I want to have some balance but mostly use it for gaming. I want to keep this system for a long time, but it would be nice if i could upgrade the processor and other components without changing the Mobo every year. I would like to keep the budget to $1200-1500 Heres what i have so far.

Case: Antec Solo mid tower
Mobo: ASUS P5E Deluxe
CPU: E8400
Heatsink: ARCTIC COOLING Freezer 7 Pro (if it will fit, anyone try it with similar setup?)
Video card: evga 8800GT
HD: 500GB, not sure weather to use WD or Seagate just want it more quiet than fast
PSU: preferably Antec not sure how many watts are needed
RAM: not sure gskill or corsair?
forgot to mention i would like it to OC as much as possible

thanks for any suggestions

yea i would suggest just buying budget parts. maybe get a cheaper mobo. gfx card is good. cheaper cpu OC it a little may be? i would suggest 600~700 watt PSU that is energy effeciant and has a long warranty. i know seasonic has some nice ones. thats one thing that can change from PC to PC without worrying about "upgrade" unless you plan to go sli or something then you might need more juice.

For HDDs, I have used WD's they are pretty good. just dont let them overheat or just make sure you have your data backed up, worst mistake you can make is not having a backup.

For Ram, i got some nice cucial memory ddr2-800 4x1gb for 50 bucks. on rebate. stuff is good and cheap.

My advice, Go budget and just rebuild in a year or two depending on how technology advances "new sockets etc." I'm not making the same mistake of spending all my money on a high end system that gets outdated too fast. Atleast this way you have a fully functional PC to sell for decent cash by the time of your next upgrade.
