You should have checked anandtech earlier. I sold off one of my frys combos for $45 shippped. It included a sempron 140 retail boxed with msi board. All brand new. At newegg, you can get some discounts on the regor 240 combo specials with board and ddr2.
i mean what mobo in specific, i need only a name and specs n stuff cause im in the AUS, so its different here. Im thinking of going with the g.skill ripjaws 4GB 1333mhz CL7 ram, and the AMD BE 955 3.2ghz, the gigabyte GA-MA790GPT-UD3H mobo.
still no idea on which is the best reliable cheapest 750w psu tho.
