That link was posted 4 years ago. I read somewhere that a lot of manufacturers were supplied with defective caps, but that was a long time ago. I wouldn't expect to see that today.
As for new systems, I just built a new PC using a MSI Neo4 Platinum motherboard and Athlon X2 4400 dual core, with 2 Gigs of RAM, and a geforce 7800GTand a Raptor hard drive. It's awesome. Xp boots in 10-15 seconds.
