Pros: I like the looks -- nice brushed aluminum. Overall quality is good. Ball-bearing fan quality is decent too -- quiet and good output. I still bought some ultra-quiet scythe fans and it made a slight difference -- surprised how little of a difference it made though. Very nice suspended HD mounting.

Cons: 1x 8-cm back exhaust fan _does not_ balance out 2x 12-cm front intake fans -- so air flow is only mediocre. You may need to turn off one fan but do some check thermal tests to make sure. Those little screws that secure the side panels are annoying to put on/off if you tweak a lot -- get some thumbscrews (see notes below).

Overall Review: Careful if you order more thumbscrews since they are the metric M3 kind, and most thubscrews don't have tight enough threading so don't work, so you need the geniune lian li kind -- they are inexpensive though so that's good.

Pros: Aluminum enclosure provides heat-sink, so doesn't need fan -- keeps it quiet. Good looks.

Cons: My drive didn't mount so enclosure didn't do it's job. The LED connectors are extremely hard to loosen and take out -- not a prob if you just put the drive in once and leave it. But if you're swapping quite a bit, this design isn't good. Also the 2 LED cables aren't labeled and you could easier mix them up.

Overall Review: Purpose of enclosure is to house drive and to enable drive to mount -- failed. When drive was properly installed, XP "computer management" utility saw drive but said space was "unallocated" -- this means that drive didn't mount (and of course I won't be reformatting the very drive I have stuff on!). When I went to work and borrowed a vantec enclosure (another brand), it worked as expected (ie: mounted). I'd another brand -- be willing to spend 5 to 10 dollars more for better quality.
