Do you folks feel the quality and reliability of the PCP&C 510's are worth splurging for? If so, keeping in mind that I do not have nor plan to buy a PCI-E video card within the next year, which is the more future-proof way to go, the Deluxe or Express? I've got a lot of expensive hardware so power supply quality is of the utmost importance, but whether these are worth it compared to their competitors is what I'm unsure about.
