Pros: Very quiet. If I unplug and replug it while my system is running, I can't tell the difference. The rest of my system fans are in the 20-25dBa-range. It feels like it moves as much as or more air than the stock 780i fan did. The quietness and air movement are likely due to the thickness of the fan.

Cons: Two matters of taste: It's an odd color, sort've a mix between shiny bronze and silver. It looked fine in my system (looked dark gray against the chrome heatsink). It does not light up like some of its competitors while costing slightly more.

Overall Review: I attached this to the stock 780i northbridge using rubber pads and adhesive to keep it as quiet as possible. Others have recommended zip ties for this purpose. I tucked the cable behind the SPP's heat pipe and plugged it into the stock fan's header.

Pros: Does push a lot of air through your case, LEDs are not too bright or too dark, I personally like the shade of blue. The noise to air ratio is fairly decent, but see below for major caveat.

Cons: 21dBA is a blatant lie. I have other fans in my case that are rated at 21-25dBA and these fans are significantly louder than they are. I was using a single one of these fans for several months and replaced many of my other fans trying to quiet my computer. After ordering and testing two more of these and unplugging the original I realized it was THIS Thermaltake fan that was making me turn up my game and movie sound so high; my machine is nearly silent without the single fan, nonetheless three of them. My case is an Ultra Grid that I've rubberized (including this fan). What's worse is that there is NO way to control these fans (BIOS and 3-pin controllers do nothing. They have a 3-pin connector with only one wire (for reporting RPMs only, not control/power) and receive constant full-throttle power from a 4-pin Molex connector, meaning you either need to find a fan controller that can regulate Molex power or somehow electrically modify the fan. Have 3 of these, can't recommend them.

Overall Review: As others have said the hardware-store screws and green-wrapped power cable can be drawbacks depending on your setup/desires, although I had no problems with either. These are good fans for people who need a lot of airflow and don't care about noise, just don't be misled.

Pros: These are to your case what earrings are to a pretty girl... Only substitute "uniform" and "professional" for "cute." All of them were threaded correctly.

Cons: They cost shipping!

Overall Review: Used them on an Ultra Grid to replace hard drive mounting screws and PCI expansion screws. They're very sturdy and easy to grip. They also lock into a Phillips head better than most flat screws I've used.

Pros: No stability problems. Excellent price. They have headroom to overclock and match FSB on Intel Core 2 platforms -- for example, even at 2000MHz QDR these can still easily be set to sync (stock 1000MHz). I have mine running in sync at 800MHz 4-4-3-10-1T 2.25V. They get a bit warm at that voltage but even without any active cooling specifically directed at them they have remained stable at those timings for several months. Other low timings have also worked with different CPUs with no problems.

Cons: Blue coolers may not fit with some people's hardware. Personally, doesn't bother me, the chrome clips/trim help the look. Packaging/manuals need more editors to monitor English translation, although nothing was unintelligible. These do not seem to overclock quite as well as some of the Crucial kits with the special D9 modules, but they do reach great timings when underclocked and cost less.

Overall Review: Have them paired with a 780i and various Core 2 Duos.

Pros: They sound great; I can hear highs I can't hear with my 2.1 set or my car's custom (and very large) 4-speaker setup; surprisingly decent for music, although I use them for surround-sound games and tuning out noise (they excel at both). They're very comfortable, can get hot if the room is much above 75F, but probably not a problem for everyone. They simulate 5.1 as well as you can expect headphones to do so.

Cons: They do deliver base, it's just nothing exciting compared to any setup with even a cheap real sub. You can't and shouldn't expect too much base from skinny headphones, though. Since I have a 2.1 setup anyway, I often unplug the speakers from the 2.1 and leave the sub vibrating while I have the headphones on. It's a great combination even when I'm trying to be quiet.

Overall Review: While it's unfortunate that some have theirs DOA or break theirs, I've had these a very long time and have moved them through a lot of risky places traveling. I've even pitched them down on my desk a few times when games go wrong. They haven't broken in any way. They've got surround hookup, they're going to be stationary at one computer, so just treat them well.

Pros: I had a 40GB WD IDE drive extremely similar to this one on an old machine and it was still going strong after about 5 years when I sold it. The amount of space was sufficient for me then. Drive was also fast enough, I hadn't really noticed a file-loading speed difference between that 40GB (Windows XP) machine and any others until I got my 10,000RPM Raptor this past year.

Cons: Little space depending on what you need; with 500GB drives at ~$100, isn't really that cheap per GB. Still cheap if you KNOW you won't ever need more space, though.

Overall Review: I enjoyed reading the review below me about it falling out of a vehicle and surviving. After handling the drive and moving it between various machines I'm inclined to believe that reviewer.
