What would be the best choice for a Motherboard & Case combo

If you were to get a Motherboard & Case off new egg as a combo what would you recommend? and if they don't have a good one available what would you suggest. I'm building a gaming and media computer and i mean extreme. the the motherboard has to be compatible with a high-end processor and high end graphics card. I also have a Samsung Touch of Color T240HD 24" LCD HD Monitor - 5ms, 1080p, 1920 x 1200, 1000:1, HDMI, DVI, Rose/Black , the graphic card has to be able to support it. which most will. ill have more ?s later

Well the case needs to have 4-8 hard drive bays. It also needs a 3.2 possessor that has the option to be over clocked and a graphics card with More than 512. it needs at least 12 gb of ram. also if you were to chose and icore7 of a quan while thing about cost what would you choose. and when considering a graphics card would you choose ATI or nvidia. Cooling is a big concern along with noise. i don't mind if the tower is big space isn't a concern .
i also want the ability to upgrade late if needed and a big power supply. would a 1200 watt be over doing it or should it be more? bling also might be nice. also i would like it if it can run demanding applications without lag as well. along if a hard core gaming option. mostly for online gaming.

12g of ram is too much - a lot of bechmarks actually run very slightly slower
