Yeah, now that it's been frontpaged on slickdeals it will probably go OOS soon. This is the cheapest it's ever been, and as a bonus no MIR involved.
I've got notification yesterday night, it's tempting, but I do not run SLI/Crossfire, so fanless 460W would be more than enough for me. That, and PSU fans always get noisy within a couple of years, and unlike case fans, they're impossible to replace without voiding warranty. This has been the case with every single power supply I've got, including Seasonics. The latest PSU in my main machine is Enermax Modu82+, which was the quietest power supply when I bought it. Well, 3 years later the fan developed a chirping noise.
So here I am, looking at this deal, trying hard not to buy - go OOS already dammit. Hoping for Seasonic 460fl fanless power supply deal on BF/CM/Christmas, kicking myself for not buying when it was $80 at the beginning of the year.
