I used to think Antec was the premier supplier of cutting edge computer parts, but over the years Corsair has come out to become the top dog. Just look at their lineup, Obsidian and Graphite Cases, KICK ASS 2.1 speakers, top-notch PSUs, exceellent HSF, and last but not least their MEMORY!! i love corsair!
but really I can only say good things about Corsair, have had their ram for ages, was impressed the moment they starting offering the 8pin PCIe modular power adapters to their PSU customers free for those that bought the 620s before the 8pin were standard.
