5 out of 5 eggsD*mned Nice Case

Pros: Removable Mobo tray, rubber mounted and tool-lessly removable HDD. Solidly made, well insulated for sound, clearly labeled, and very well laid out. Provided standoff-driver a very nice touch. Makes a VERY nice home for the E6600 on a D975XBX2KR, Plextor CD/DVD and the 500GB 7200.10 I put in it.

Cons: 80mm exhaust fan is small, so therefore not the best from a strict airflow~cooling~overclocking point of view. Instructions aren't in the best English, but the case is laid out and marked more than well enough to not need them. So meh...

Other Thoughts: Built this comp for my sister, who has 3 pre-computer-using young boys. So I actually chose this case because it has a LOCK to keep out curious little fingers. Pleasure to build this one from more than one perspective.

4 out of 5 eggsHIgh temps with this case

Pros: Nice case with motherboard tray you can remove. Very well insulated and quiet which leads to the cons.......

Cons: This case is not your average Lian Li with cool temperatures. Ran a E6600 about mid to upper 40C. Ended up cutting a 4" hole lined up with the CPU on the side removable panel and installed a quiet 120mm fan. Temperatures dropped 10C right away with the cool air that was brought into the case from the side. Lots of insulation tends to trap lots of heat from the components which can heat the case up. I don't think the front fan brings in enough cool air and they probably should have installed a side panel intake fan instead of the rear bottom exhaust fan.

Other Thoughts: I am running a 8800GTS 320MB video card which really heats up the case and has its own temperature of 58C. But I would be aware of the potential for higher than average temperatures with this case. But if you are handy with a drill and hole saw if needed you can alleviate the heat in your case with one side intake fan.

5 out of 5 eggsGreat Quality

Pros: Very solid construction, extremely quiet! I had a PC-65B from LianLi before, and now I find myself having to look to see if my PC is on! I can barely here it, even with all the fans at max. they give you the tools you need to assemble, and easy to follow instructions (if you really need them). The rubber hard drive spacers are great--I have 4 HDs in here and don't hear a thing from them.

Cons: Price. Granted you are paying for quality, but it is a bit steep. Also, since it is so well sound-proofed, it does seem to trap some more heat in than other cases.

Other Thoughts: Great case, I recommend it to anyone who wants to get an almost totally silent solution with a great, solid design for a new PC case.

3 out of 5 eggscould be a great case.

Pros: suppose to be silent, but have not tested. build quality seems good, except the manufacturer defects. most all the features i am looking for.

Cons: 2nd case. both had small budges on the front cover where the 12 screws on the inside of the cover had been tightened too much. plus some minor scratches on the outside. i expect more from a $200 case. had to return both. a little tall for me.

4 out of 5 eggs

Pros: Clean design, IO audio & USB ports, removable motherboard tray, removable hard drive rack, removable PSU slot, and locking mechanism for front chassis.

Just a small list of the wonderful features Lian Li gives you for a reasonable price.

Cons: My only complaint, and was a complaint I had about the Lian Li PC60, was the motherboard mounting technique. The screws I was given did not even fit into the motherboard tray as they should. I had to kind of ghetto rig the mounting with different screws.

5 out of 5 eggsOutstanding

Pros: This is absolutly the most quiet case I have ever own. The case can easily be stripped down to the bones and put back together with thumb screws

Cons: The only slight con is the power light is like a laser. Too bright for my taste.

Other Thoughts: Worth the money

5 out of 5 eggsExcellent Case

Pros: This is one of the best cases I've seen. The attention to detail is obvious. Couldn't find a sharp edge anywhere. It's pretty quiet for all the fans it has. Plenty of room inside case, even if you have a extra-long video card. Slide out MB tray make installing MB a breeze.

Cons: The filter for the front fan is a bit difficult to remove for cleaning, and they could have allowed just a bit more room between the HD enclosure and the side of the case.

Other Thoughts: Lian Li's prices are a bit steep, but you definately get what you're paying for. Comes with everything you could possibly need or want in a computer case, it even comes with a special screwdriver for installing MB mounting posts.

5 out of 5 eggsLian Li rocks

Pros: SOLID construction.
Cozy interior.
Very WELL planned modular drive cage, I've never had hard-drives sit so well.

Comes with noise dampening rubber standoffs for hard drives.

Thumb-screws for almost anything.
By far, the fastest case I've ever worked with.

Cons: I had trouble finding the keys--only to discover them taped to the bottom of the parts box which was situated in one of the drive bays of the case when it arrived.

Sound matting may tear if you aren't careful with cable clips.

The wiring connecting the input panel at the top of the case gets in the way when installing devices in the 5.25" bays ( i just removed it and re-installed it later).

Sliding motherboard tray is a little flimsy when removing it, but won't cause any issues.

The front door ball-bearing latches are a little on the loud side.

The support bar at the top of the case needs more clearance for feeding a few cables over it ( helps get them out of the way )--I would recommend raising the height of the case by just a 1/2" or so.

Other Thoughts: The PSU duct scoop doesn't fit quite right. I had to push against it with a lot more force than should have been required to mount it after installing the power supply.

As others have said Lian Li builds awesome cases, but their English instructions are lacking.

No rubber stand-offs for motherboard or rubber in-lay for power-supply, but those shuoldn't be vibrating anyway--nor would I have expected them to include these.

Overall- i am very pleased with this case. If a full-tower just like it were available, I may have chosen that--but I just like lots of space.

5 out of 5 eggsNice Quiet Case

Pros: Nice solid construction; everything fits the way it's supposed to. The fit and finish is superb; a nice change from the beige boxes I used to put together. Nice fit with my Gigabyte GA-M59SLI-S5 (Silent Pipe)and Seasonic 600W (modular) power supply. I haven't built a system in over four years and it was a pleasure working with this. I read a lot of reviews before settling on this case - didn't want anything that glowed in the dark, just something that looks good and keeps it mouth shut. Surprisingly light compared to the steel cases I was used to. Well worth the premium $$$. Did I mention it's quiet?

Cons: One of the feet was a tad bit loose.

Other Thoughts: The (detachable)VGA cooling fan MIGHT not work with some of the silent video cards if the card's heat sink or cooling pipes extend much over the top of the card. I went with a standard fan-cooled card so it wasn't an issue for me. Be sure to plug in your modular cables on your power supply before installing the power supply.

5 out of 5 eggs

Pros: The quality of this case is unbeatable. The craftsmanship just makes you want to sit back and study each angle for an hour, gazing at the aluminum beauty. It's by FAR the quietest computer I've ever built - completely going beyond my expectations on acoustics. The front door is SOLID and the latching mechanism will last 100 years. It even includes a nice tool to secure the motherboard stand-offs (first time I've ever been given one for free!).

Cons: For being tool-less, it was still a pain to get the CD-ROM bezels off. I didn't have to remove the front cover (as others have); I just used a screwdriver to push in on the tabs from inside the case and then pulled with my fingers. It would also be nice if the rear intake fan had a dust filter on it. The stock rear fan is quiet, but has a very noticeable ticking sound so I replaced it with a PC Power & Cooling Silencer fan.

Other Thoughts: Others have reported that turning the rear fan around reduced their case temps; I did not notice this. I have gotten the lowest CPU/motherboard temps by far by just leaving the fan configuration as-is. Lian-Li engineers know what they're doing!

This is simply a beautiful, well-crafted, quiet case and I highly recommend it.
