I have bought and installed 8 ECS K7S5A mobos on various systems for my friends and family, and it's the only MB I use with them. Its great because it has everything already on board except a modem and video. I used to have an Abit kt133-raid mobo, and it always freaking locked up. The K7S5A is about 1/3 the price, and provides much better features and performance. It's easy to upgrade too. You can start out with a duron and sdram like me, and then upgrade as you find good deals. It supporst both DDR and SD ram. AS for the duron, you're getting it for $30, which is a pretty good deal.
