Pros: I will start off by saying that these drives are great thus so far. Seems to be the best bang for your buck. I bought 2 of these for my Dell XPS M1730 and set them up in RAID 0. These drives replaced the stock 120gb Fujitsu that came with the laptop. Noticed dramatic speed increases right away. Vista score went from a 5.1 to a 5.9. They seem to run fairly cool and quiet. Honestly i didnt expect for them to run this quiet. I can barely hear them seek. My boot up time went from 40 seconds to 25 seconds. This laptop has been pretty much powered on since I installed them 5 days ago. Still running well. No noticeable vibrations like others have said. Newegg had them shipped to me in 2 business days. Hats off to Newegg!!!!!!!

Cons: As others have stated, they do make random clicking noises when they are at idle. I dont really feel a need to get replacements or even feel that this is a defect. The stock Fujitsu drive that i pulled from this made the exact same clicking noise as these ones do. I have owned this laptop for over a year and i have always heard this clicking. I think if this was a drive issue, i would have had a hard drive failure a long time ago. Also it would have been nice if these drives came with caddy mounting screws. My battery life has decreased but this was to be expected.

Overall Review: Seems as if though choosing hard drive brands is almost like a Ford vs. Chevy thing. Especially between Western Digital and Seagate. I have owned both Seagate and Western Digital drives. The bottom line is there is no such thing as a "fail proof" mechanical hard drive. I have had both WD and Seagate drives fail on me in the past. I read all the time where people say one or the other brands are "junk" just because they whine about loosing all of this important data. NEVER trust any hard drive with important data regardless of how good of a drive you think it is. Make sure you backup everything you feel is important on another external hard drive or other storage device.

Pros: Its big!!!!! You have been warned. Tons of space for your video cards, hard drives and 5.25 inch devices. 4 fans included that make good airflow. Very bulky,heavy and sturdy and also comes with castors that make transportation easy.

Cons: None

Pros: Modular cables, 1000W, easy to install. Has been running smooth in my new build. The blue fan LED is cool looking.

Cons: None. But the ATX harness could have been longer. Had to get an extension cable. My fault for getting such a big case.

Pros: It works as it should. The fan adjustment knob is nice to reduce the noise level. At idle my temps are no higher than 35C and under full load, no higher than 50C on all 6 cores. But I have not overclocked yet. This is a cool looking heat sink if you have a clear side panel on your PC.

Cons: None. Lots have reported that it is hard to install but I had no issues. It is large so make sure you have a good sized case. Take measurements, and do your research to make sure it will fit.
