Pros: Super, duper, efficient. Well over 91% efficiency from 20% to over 100% load. Fan is whisper quiet. Should last forever, given its solid build and resistance to heat.

Cons: Can't set the fan to engage at custom temperatures.

Pros: Got mine for under $100. Lucky me. Super solid construction. Incredibly quiet and efficient. Very fast for 5400 rpm. I've got 3 in a Raid5 and they're awesome.

Cons: Not a 7200RPM drive. A bit too expensive now. Wait for prices to drop (6 months?).

Overall Review: If you want a bit of a performance boost, you can disable the power-saving options to have the platters spin at all times. Seek times will be much faster on the initial seek after being AFK.

Pros: Amazing boot time and application response. I use this for my OS and a few critical apps/games. So fast.

Cons: Err... not 6Gbps? Could probably use that bandwidth, since it clocks above 3Gbps in tests.

Overall Review: Be sure, FYI, to put your pagefile and other high-access files on your disk drives since SSD's have a limited number of read/write cycles in their lifetime.

Pros: Very well constructed. Great airflow design. I get tons of airflow with very little noise. Keeps everything under 40c even under full load. FILTERS! Usually they're impossible to find on a case this cheap. So nice to have. Simple aesthetic. Great placement of buttons/IO board. Easy to work in.

Cons: A bit hard to pick up. Could have used a bit of a handle somewhere on this 20 lb thing. Power supply filter is inaccessible once the PS is installed.

Overall Review: You'll not find a better case at this price range. GREAT ventilation options, really great drive cages and cord mgmt spaces. Awesome to have filters.
