Pros: Good enough range for me, but I haven't tried it past 10 ft yet. Attractive set overall. I can use the keyboard just fine to access the BIOS on my computer (Maximus III Extreme).

Cons: Doesn't come with an extension cord/dock for the USB receiver like other sets do which may be necessary for some people. Price is a bit steep, so get it on sale if you can.

Overall Review: If you can't access the BIOS on your computer with this keyboard, your computer may not like any USB keyboards or just some in particular. The scroll wheel has a feature that by default chooses whether to enable/disable the clicking/detenting based on what app you're using and what it deems appropriate, which was new for me. It can be set to always click or always freewheel if you prefer too.

Pros: You get the required connectors for fairly cheap.

Cons: You have to know what you're doing and fix this stupid thing or risk smoking something.

Overall Review: The dummy who designed this wired it up to make a dead short across the video card. You have to either clip or remove the pin from the 4 pin plug for the brown wire that is directly between the two yellow wires in the 6 pin plug. That pin in the 6 pin plug is supposed to be either +12V or disconnected, not wired to the power supply ground! Be careful using only one of the 4 pin plugs as others have suggested; doing that only supplies +12V to one of the three +12V pins on the video card and may cause problems with power hungry cards. Just use some tweezers or a small screw driver to flatten the pin retaining ears and remove the pin for the offending brown wire and tape it up or heatshrink it.

Pros: The new mounting system is nice, quite a bit easier to use than the system used on the 212 EVO.

Cons: The manufacturing process for grinding the base flat has taken a turn for the worse. This design puts gaps between the copper tubes at the base that should be filled by the aluminum base. Not on mine. The copper tubes were proud of the aluminum base by about 0.005-0.010". By the time the base was lapped somewhat flat with 500 grit wet/dry sandpaper on a flat stone, there was next to nothing left on the walls of the copper tubes. There are still some gouges in the aluminum next to the copper, but there are dents in the thin spots showing evidence that the copper walls are ready to break through. The walls had to be nearly gone already before I even touched it. Not good for cooling hot CPUs.

Overall Review: If you can afford it, go with an offering from the famous Austrian company. I need to build another 10 workstations, and the poor quality on this model has convinced me to look beyond Cooler Master. If you're stuck in this price range, get the Hyper 212 EVO instead. I've used at least a dozen Hyper 212 EVOs in the past with good success. The base of the EVO has the copper tubes all wedged together, and they're usually flat enough that just a few light lapping passes with 500 grit on a flat stone will make them perfect.

Pros: Came free with a processor purchase?

Cons: Requires a subscription to play beyond the 10 free days, an expensive one in my opinion. You'd have to be nuts (or have money flowing out of your ears) to pay the retail price for this and then pay a bloated subscription fee on top of that.

Overall Review: This is really a zero egger for me.

Pros: Inexpensive. Solid connectors.

Cons: More fragile than eggs evidently. It worked fine the first day, nice and bright transmission through the cable. Disconnected it the same day, reconnected it the next day, and it didn't work. It was not kinked or wound tight, but the transmission was suddenly dim.

Overall Review: Fiber optics are fine for pushing tons of data across the continent through buried conduits, but they have no place in a home theater system if they have to treated this carefully.

Pros: Inexpensive. Passes signals just fine, even the audio signals. Lets you use a DVI cable instead of paying for a new HDMI cable.

Cons: The HDMI connector does not fit exactly tight into the video card I'm using, but I don't see the signal degradation another reviewer reported. It fits a tad loose such that the cable would probably pop out if you bumped/tugged it a bit hard.
