All of these parts are used and I make no guarantees about any of them all I can say is that they were all working when I removed them. I finally got a new PC with 3 M2 drives and also put in a PCI host card with 6 more Sata's. One of the racks makes a beeping sound when you first put in the drive and lights up even with the key off but you just reset it on the front to get it to stop. The trayless EZSwap one is a generic no name one and it was always sort of stiff when swapping. Buy at your own risk. Thats why I'm selling CHEAP!PS: At any rate I'm ready to let some one else enjoy it. I'm sure you will be just as happy with this purchase as you would be with a new one. You can be assured that I have tested it for you, plus it's cheaper and you'll get it faster. I live in the Charlotte, NC area and will carefully package and ship just as soon as payment (Paypal Only Please) is received. I make a special effort to ship (USPS) the same day if at all possible. Thanks, worknathome.
