I recommend ASUS or Gigabyte motherboards as better quality alternatives. Any model z68 will do.
Thermaltake power supplies are not the best of quality, plus 750 watts is way overkill. More wattage does not equal better quality. These are much better and will still have plenty of power. http://www.newegg.com/Product/Productcompare.aspx?Submi...|17-341-050^17-341-050-TS%2C17-207-013^17-207-013-TS
