OverviewCustomer ReviewSpecificationsProduct Tour
Sileo 500: Cooler Master’s latest silent mid-tower chassis, equipped with acoustic foam sound insulation material on each side, delivers perhaps the quietest experience that you have ever had in a case.

WIth anti-vibration pads inside the detachable HDD trays, the case reduces noise and includes vibration reduction pads for the power supply. With five 5.25" and five 3.5" drive bays (including four hidden and one external), you have room for lots of storage! Excellent cooling is provided by 120mm fans front and rear! Quickly upgrade and maintain your computer case with the tool-free design. It’s great for the do-it-yourselfer who needs a lot of flexibility!

Easy USB, e-SATA and audio connectivity is provided on the middle I/O panel. While you want a case that both satisfied you with its price and no noise, the Sileo 500 is the best choice for you!

EXCELLENT, SIMPLE, AND VERY QUIET

white Reviewed By: DaveO on 2/26/2009
Rating + 5
Tech Level Tech Level: high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: If you’re looking for a basic and practical case this is it. It is a very quiet and I recommend it HIGHLY paired with a very quiet and efficient power supply. Although I have never crossed the perfect case, this case provides moderate cooling for the non overclockers except with Zalman cooler or water cooling (Read below).
Cons: No dust filter, Hard drives squeezed close together (I am not sure if the fan blows that much air past them, but atleast the fan blows directly on the hard drives).

If this had a dust filter and had a larger gap between the Hard Drives this would would be a near close to perfect case for those looking for simplicity design along with whisper quiet operation.
Other Thoughts: Because it has sound dampening foam I would recommend keeping your computer in a some what cool place as the foam keeps heat in. The intake and exhaust fan runs just fast enough keep things cool. Designed for quiet operation the fans run at a lower rpm for a reason (no over powering fans to create noise). I do not recommend overclocking, unless you purchase a water cooling system or an upright Zalman cooler (designed like the 9500A) that blows the heat right out pointing directly at the exhaust fan. Overall I am very happy with it as I do not overclock like I used to. I prefer cool, quiet, and stable computing.

This user purchased this item from Newegg
Pros: Based on its specifications, (insulated design, front panel eSata port, anti-vibrations pads, brushed aluminum front panel, etc), and on user recommendations I purchased this unit. Here are my findings:
1) It's black, (if that is what you looking for), and it doesn't look half bad. I would even call it simple, but stylish.
2) I needed a case without a hinged front cover that only gets in the way when you use your DVD drives, etc. frequently.
3) It does have a front eSATA connector. I pray it works; I did not have a chance to test it yet.
4) The LED, switches, SATA, and USB cables are clearly marked, and good quality. That is honestly all I can think of as good.
Cons: 1) Cheap is the keyword what you can safely apply to this case. Not inexpensive mind you! This has no power supply, but a brief search listed 54 cases at newegg with P.S. Granted many may not have front panel eSATA connector or sound insulation. But that alone a case will not make!
2) The sound absorbing pad is not applied evenly, it is especially annoying on the inside of the removable side panel the most visible place and one that should be the easiest to fit. The padding is not even square; it looks like someone was cutting it out with an x-acto knife (after one too many beers) leaving 3/4 inch uncovered areas. Where it does fit ok, above the power supply, it must be ripped off to allow the installation of the supply. Alternately you could bend the supporting brackets for the PS. The choice is yours.
3) The front panel is not aluminum, it is plastic. Nice heavy, strong, but the only thing aluminum is the external driveways covers that you must remove when you install you
Other Thoughts: I almost never write reviews about items I buy. I figure that hundreds of users already said whatever was to be said. This case changed my mind. I cannot imagine that one person can be quite this bad; it must have been designed by a committee of like minded people. If you suspect that I do not recommend it you are right. As I see it, during the 30+ years I am in the computer business almost everything improved except computer cases. We have 3.5" Terabyte instead of 16" 20MB, hard drives (yes that is mega for you younger whippersnappers), and 32KB memory on a full size expansion card does not cost $3-400 any longer. Everything, except computer cases. They are just as noisy, most of them are flimsier, etc. or rather even more so. I needed a case for audio-video workstation so quiet operation was essential. In the past I used mostly Antec cases (at least a dozen, built for myself and others), and while I never had any problems with them I never was happy with their noise level.
Manufacturer Response:Thank you for your feedback. All Sileo 500s have an aluminum front bezel and acoustic insulation. Please contact Cooler Master USA support and we will gladly arrange and exchange your Sileo 500 for a new one. You can contact support through live chat or through the phone at 1-888-624-5099.

Good Case... If you dont mind a little modding.

white Reviewed By: Chz on 9/30/2009

Tech Level Tech Level: average - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: The case is built well and has a nice look with the blue pwr/hdd lights. Feels pretty solid and absorbs sound very well.
Cons: The foam insulation which touches most every inch of the inside walls is equally absorbent to heat as it is sound... not good for beastly GPU. The fans that are supplied with the case are not anything special. Prepare to replace them if you are a high end CPU user.
Other Thoughts: I had a x4 955 with stock heatsink running on board graphics and my cpu idled around 40c. After replacing the 120mm fans with 70cfm silenx fans and ripping out all the foam I got my idle down to 36. My computer was louder, but much cooler. I later installed a core-contact freezer heatsink and realized I probably could not have done so with the foam still applied. Overall, a great case for the money.

Tech Level Tech Level: average - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: Attractive functional look. Doesn't look like a jukebox. No windows. No bright lights. Lots of bays. Deep enough for a tall aftermarket CPU cooler. Sound damping makes it quieter than it would be without it. Sound damping mounts for the power supply. I got it on sale with free shipping. Arrived quickly and in good condition from Newegg.
Cons: Runs hot with stack fans. Cable management requires a lot of creativity. Expansion slots require screws to hold PCI boards because the tool free locks are not secure enough. Front panel switches block fan and require lots of creativity if a filter is desired. Sound damping pads are a bit crumbly and are not cut or installed accurately.
Other Thoughts: I removed the hard drive cage to allow more air flow and mounted the hard drives in optical drive bays. I put a pad on my bench and set the case on its top to let gravity help rather than hinder power supply installation. I added speedier fans to so the noise level increased. Even with a modular power supply cable management is very difficult. When I get some time I'll bring out the drill, nibbler tool, and Dremel so I can stuff some cable next to the optical drive cage. It's possible to remove the tool-free optical drive bay devices and use screws. I may try the CoolerMaster 4-in-3 bay kit (N82E16817993002) or the Titan (N82E16835192016) to get more cooling.

Tight PSU Fit, Silent Case

white Reviewed By: Bot-chok on 9/9/2009
Rating + 5
Tech Level Tech Level: somewhat high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: -Mostly toolless install
-I like the simple look overall
-Price is good for construction quality
-Super quiet
-Will fit a TRUE 120
-Nice looking
Cons: -Not much airflow
-Tight fit for PSU (but it DOES fit)
-I don't like the feel of the power and reset buttons
Other Thoughts: Because of the placement of the foam, the PSU is a really tight fit. I really thought I was going to push the PSU right out the top of the case! I am going to buy this again not for gaming but for lighter tasks. I don't think a heat breathing video card could survive in here.
