I think I have everything picked out correctly for the upgrade, but I just wanted some feedback from people who have done this in the past before I make the purchase. The only thing I am not sure about is the current F_PANEL connection seems to have less pins than the new board. Is that a problem?

Should I switch out one part at a time and if so what order would you recommend? Also, I will be upgrading from windows vista 32 to windows 7 64, should I do that upgrade before or after installing the new motherboard?

Thanks in advance for the advice.
I'd say you are all set-the front panel having less pins will definitely not be a problem.Thanks for taking a look.

I did think of one more question though. My monitor only GOES to 1360 x 768 so would the video card I picked be overkill. The Radeon HD 6770 is quite a bit less so would the improvement be worth the $100 difference at that resolution.Any reason for selecting a micro-ATX board ? ?Quote from: patio on September 26, 2011, 12:41:38 PM

...Plus my wife is stingy on letting my buy new computers so this is a bit of a stealth upgrade...

i find cases on tree lawns every Sunday nite...some are pretty nice and servicable...
