Seems to have all the bells and whistles (though I wish I had bought the modular version). I definitely agree about the cheap no-name PSUs, I've seen some USD$10 ones go up in smoke after just a few minutes of use. Based on the little info I could find Googling it seems the most likely explanations are: IRQ handling weirdness (but that was more probable in older motherboards and kernels) ahci driver issues (I will reboot with the controllers in "legacy" mode to use the non-ahci drivers and see what happens) a bad drive, bad cable, bad controller, bad sector, something physically ba= d. Overnight I copied several hundred gigs of data (and still going) and the error has not been reproduced. Before installing, I did a full SMART test (a few hours) and a badblocks read-only test (even more hours) and neither showed any errors. I did not do a full read/write test, though. I haven't heard any unexpected noises coming from the drives (no clicks of doom), though I have so many fans going it may be hard to hear. Thanks.
