Pros: I own 3 of these. They keep every processor I have put them on cool and quiet. (30*c idle, 36* load with MX-2 paste on a I5 3570) (29*c idle 39* load with MX-2 paste on an I7 3820K) and (32*c idle, 45*c load with MX-2 paste on a Q9550) All of my machines tested running prime 95 torture test maxed.

Cons: Price, but at some point each year they are always on sale.

Overall Review: Forget the rest, buy the best! I only use Zalman coolers in all of my builds (20 in the past 3 years). Zalman products never fail, and they are extremely quiet! Never had one not fit either on many motherboards for the custom builds I make and sell.

Pros: Is a very well designed case with lots of features, including USB 3.0, open back for CPU cooler. Is very near impossible to add any case fans to this case. 1.If you use a Zalman 9700 or larger SPU cooler will bot be able to use case fans in top of case. 2. not for use with ASROCK motherboard Etreme 3due to heatsink on north bridge, the exhaust fan will not fit.

Cons: Is very near impossible to add any case fans to this case. 1.If you use a Zalman 9700 or larger SPU cooler will bot be able to use case fans in top of case. 2. not for use with ASROCK motherboard Etreme 3 due to heatsink on north bridge, the exhaust fan will not fit.

Overall Review: if you don't plan on overclocking, or have a tall north bridge heatsink on your motherboard, then this is a very nice case. If you have a northbride heatsink and cooling fan close to output panel, or are planning to put fans in the top for extra exhaust then you might look elsewhere. Not very useful of a case if you can't have any exhaust. Great features, poor design.

Pros: USB 3.0 in the back of your case and an internal header 19 (20) pin USB 3.0 header for ports on the front of your case. Very affordable solution to upgrade an older 775 socket motherboard to USB 3.0

Cons: People please read the requirements before purchasing. Does require PCI-Express 2.0 motherboard. Not a con, but some people review it as such for some reason.

Overall Review: Pair this with a Biostar 2 x USB 3.0 front case bracket or better yet a Syba MRA55006 5.25 multidrive hotswap with 2 xUSB 3.0(1x3.5" HDD hot swap and 1 x 2.5" hot swap front case bay and turn any old rig into a modern marvel!

Pros: USB 3.0 with 19 (20) pin header cable. Hot swap 2.5 and 3.5 bays. What more do you want? Sata 6.0GB speed USB 3.0 Super Speed! Everything you need to turn your case into a real workstation or upgrade a case for computer repair persons.

Cons: The only con I have is that the lever to release the 2.5" bay door looks like a button you should press instead of a latch you should pry. It took a little bit of time to figure this out. It should look like a latch instead of a button because there really is no place to really grab it to open other than using your thumbnail. Instead you are to slide it to the right to open. It isn't worth taking off an egg, because let's face it, this is an awesome value for all you get.

Overall Review: Very easy to mount and lines up with standard holes. Seems well made and hasn't given me any issues whatsoever. A great addition for any case upgrade for a very fair price.

Pros: This is a great item for those looking to upgrade their case to modern USB 3.0 front slots. The price of this is much cheaper than you would think. Uses an onboard 19 or 20 pin connector and not some run out the back USB plug.

Cons: Finding a quality bracket for your case to mount with, but not the problem of the product just a side note.

Overall Review: You may find it somewhat challenging to find a 5.25 to card reader bracket for your case. It should also be noted that the item can be detached from bracket and mounted directly in place of your usb 2.0 connectors currently in your case, provided a fire wire port isn't in between your slots, but who uses firewire anymore, heck just remove that too. That is probably one of the best features of the item is being able to directly mount the cable and ports into your existing USB 2.0 ports.

Pros: 4 External USB 3.0 ports that work.

Cons: The slots can interfere with the slot separators on some cases.

Overall Review: Really the cheapest choice for adding USB 3.0 to an older computer using a 775 chipset and PCI Express 2.0.
