An EXCELENT resource for K7S5A owners can be found at
ocworkbench there are Thousands of K7S5A owners who post here, they actually had to archive the forum once already because it had so many posts on it. You'll see alot of people having problems, but often you'll see a "whos works great?" post and literally hundreds of people come from the woodwork to brag about there sucess stories.
(I feel like a broken record for saying so many times, Buz2b is probably sick of hear me by now

But, I've built over 15+ systems out of this board (possibly 20) over half of them were the earlier revisions and I've only replaced a few Cmos batteries and updated a few ECSD's in the bios manually when something seemed a bit off,
Now I did heed the advice that was all over the net when I jumped onto the k7s5a band wagon, I bought decent quality power supplies and almost exclusivly crucial ram (it was super cheap back then... now with this new stuff that is cheap I dont knwo what its like) and havent had any major problems with ANY of them.
I give it 2 thumbs up, but its now begining to show its age. but I still feel it fills the niche it was ment for better then any board on the market.
