IF you Sammy has the same inputs as Mine I would seriously consider using the VGA Input instead of the DVI input, use the PC input source selection, The VGA input supports 720P direct off the video card, I tried both methods when I set mine up & this route was the most trouble free.
At a 1280X720 HDTV Resolution and the Picture quality is virtually identical to using the DVI input on the VGA PC port at least you would be hard pressed to see any differance, this eliminates any overscanning issues, you do lose about 1" around the perimeter of the screen using this method but it eliminates a lot of issues. Set up your video card using the catalyst drivers to run in HDTV mode 720p Forced @ 60Hz and this will eliminate any overscanning issues you may be experiencing, its just the simplest method to use with most Sammy Dlp's, and it works great. Congrates on the successful build completion.
AS far as fan noise antec fans are usually very good niose wise, but you might want to consider switching the up the fans to High and then using a couple of Zalman Fanmate fan controllers Around $7 bucks each to more precisely control the fan speeds & noise level.
