My local Fry's has the xp2600 bare cpu with ecs via kt600 mobo for $84. Add a heatsink, and you'll get a decent setup for about $100. If it works. Some ecs boards work, and some don't. But at least you'll have 30 days to test it (for the mobo, 15 days for the cpu). If the board breaks, you might as well toss it. Ecs charges a $30-35 handling fee for their 3 year warranty, last time I checked. So the bottom line is, it's a gamble, but the mobo is almost free.
