Newegg is the place to shop. I use a shuttle ak31 version 3.1, and newegg has a refurbished one for only $59 with free shipping. If you bought an oem cpu, I suggest a copper heatsink for better cooling. The retail one works fine if you don't overclock. Sell you sdram in the paper, and make the switch to ddram. Check newegg's refurbished section for many other items. They have a good selection of cases. I recommend any case that has a 350 watt amd approved power supply. If you don't find one you like at newegg, try directron or electroseller.
