Pros: Convenience when working, looks good, inexpensive.

Cons: Loses access to the card reader slots. The SATA cable does not connect very securely to the MB connector.

Overall Review: Unlike others here, I had no problems whatsoever with the fit. Had some initial problems with the setup until I figured out one of my motherboard USB headers was bad. All three of the USB connections work well which is nice. The audio connections worked fine, after I made the appropriate changes to the MB BIOS and the Realtek I/O settings. I don't have an eSATA device yet so I cannot speak to that. No IEEE 1394 on my MB so same goes there. I just have SDHC cards so that is the only card reader slot I have used. That has worked very well when the slots are recognized. The reader slots show up as four removable disks when everything is working. Unfortunately, I have had those "disappear" twice now and the only way I have been able to get them to reappear is to disconnect the USB cables from the motherboard, reboot without them, shutdown and reconnect, then reboot again. A pity because without that problem, I would give this thing four stars.
