Pros: I was skeptical of the wireless bits, and the 7.1, but after testing these out for a few weeks with music, media, and most importantly, games, I can say with confidence that this is probably the best headset I've ever used. *The 7.1 gimmick isn't universal, but in games where it's enabled (mostly shooters, I used Bad Company 2), it makes an astonishing difference when compared to an actual 5.1 speaker setup - the immersion factor is huge. *Voice quality on the mic was exceptional, although I doubt the voice masks will get much use. *The included software makes set up a breeze, including EQ, voluming, and custom profiles for the three "G" buttons on the left cup. *Volume control is also right on the headset, and interfaces seamlessly with win7.

Cons: *While these are exceptionally comfortable for their size, there's no avoiding the fact that you will notice these weighing you down after extended use. *It's a shame that these don't take advantage of the Logitech Unified Receiver, but since require a usb cable to charge anyway, so not a big deal. *The "hockey puck" has more than enough cable to run to the headphones while in use, but the usb cable to your pc may run a bit short depending on your setup.

Overall Review: These'll work as advertised - I was making a sandwich about 30 feet away from the receiver and was still getting crystal clear audio. Confirmed that the mic works at that range as well.

Pros: Comfortable for a relatively small/portable mouse. Satisfying scroll wheel (both stepped and smooth mode).

Cons: I've used three of these (two for work, one for home use), and all three have had the same problem: the wireless receiver looses its connection to the mouse, causing very choppy mousing, scrolling, and lost clicks. This makes the mouse unusable in general - buy this, experience the signal loss once, and you will forever live in fear that it will reoccur.

Overall Review: Logitech forums indicate that the problem can be caused by static charge buildup, and that removing the batteries and holding down all the mouse buttons for 20 seconds can fix this...temporarily. I tried this, as well as different USB ports, positioning of the mouse relative to the usb, etc. and the only thing that worked with relative consistency was placing the mouse no more than three inches away from the usb dongle (unbroken line of sight). Useless.

Pros: - Huge. This thing is enormous in every direction, and very easy to work with as a result. - Side loading HDD cages are brilliant, and the SSD support is built in - no adapters necessary. - Air filters are a good idea

Cons: - Depending on the layout of your motherboard and the length of the cables you get, it can be tricky to get some cables to stretch, especially if you're using the routing behind the back. - DVD cage tool-less design is not very good at all - no case should require you to snap off bits of metal and then physically force a drive through.

Overall Review: The door looks great - wish more of that material was on the rest of the case.

Pros: - Easy to install - Good signal (70-80%) at range, through walls

Cons: - Horrible GUI on the included disc - Having 3 antennae is cool, but positioning them can be difficult on a desktop. The PCI slot is usually above the PCIe slot on most motherboards, and all the rear ports (audio, usb) are usually coming out right above that, which doesn't leave much space for antennae

Overall Review: So far, no dropped connections or unexpected behavior.

Pros: - BIOS (UEFI) is very easy to use - Layout is good

Cons: - Felt thin during installation, almost fragile compared to other motherboards - After a couple months of use, started getting BSODs at startup - thought this might be the SSD I had installed. Nope. Started getting freezes at desktop in win7 - thought this might be the SSD or new Nvidia drivers. Nope. After trying multiple HDDs, GPUs, etc., I finally took all of my original parts off of this thing, put them on an old motherboard, and lo! No more BSODs! No more freezes!

Overall Review: Help docs weren't too helpful, but that's what the internet is for. Not planning on bothering with tech support on this - got it at a steep discount. Think I'll just pony up for a better one (maybe even step up to Z77).

Pros: Great timings, perfect for any i5 build, quickest sticks for the money.

Cons: Felt a little tight going in, remember to use the flat areas on the sides or you might bend a fin. Also, if you haven't read any of the other comments, the timings do not default to the advertised timings - you have to tweak the timings in your bios. Not hard to do with most mobos/manufacturers, but be aware.

Overall Review: Perfect fit for any serious gamer, but enthusiast overclockers with bottomless pockets should keep looking.
