5 out of 5 eggsIt's a Silent Winner

Pros: Try one and you'll see (not hear) why several PC builders are cropping up with their good packed in the Sileo RC-500. It's roomy, tasteful, and quiet. Simple and elegant, and has tons of 5.25" bay room for building a system with removable drive bays (I chose trayless SATA ones and have been delighted! Pop 'em in and out all day with ease!). The discretion is then yours to bling it up with lights via the bays (Fan controllers and such). Very nice design and looks all around. Well-marked motherboard standoff locations are appreciated. Lightweight and not flimsy or tacky in any fashion. When you've matured away from the UV lights, scrolling message RAM LEDs, and case windows with dragons and radon symbols on them, this is what to get yourself as a graduation present. Under the desk, or in the living room as an HTPC, this case is the big win. ^__^

Cons: Okay, so the PSU is a tight fit. Hardly a complaint... When you decide to get over this, man up and push into that foam with enthusiasm, you can also be assured a marked end to PSU-on-case vibrations. Fits any size PSU I've thrown at this model! One weak spot: The default fans are *not* top-shelf, so if you intend to build a real roaster in this case, keep that in mind and spring for some fans with more oomph. Yes, the magic sound foam also retains a little warmth - simple physics, kids. But again, a decent fan controller and some quality fans will top the package off nicely.

Other Thoughts: The anonymous poster driveling on about the bezel being plastic vs. aluminum seems to have a poor grasp of metallurgy in general. I applaud CoolerMaster for offering to replace his "special" case with a new one. He may have been confused and talking about some other model. Plastic doesn't get this cold in the winter...

4 out of 5 eggsGood Case... If you dont mind a little modding.

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.

3 out of 5 eggsIt's okay but ...

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.

5 out of 5 eggsTight PSU Fit, Silent Case

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.

5 out of 5 eggsI like it

Pros: It's quiet, ergonomic, tool-less, and relatively inexpensive. My quite power supply fit perfectly. I like the snap-in plastic rails and side-facing 3.5 hd cage that allow you to just slide in your hard drives. Decent room for a full-size AT motherboard. I even like the 'vertical-bar-buttons' for power-on and reset on the front. They are easy to find by feel in the semi-dark. The front face has an interior lining of vinyl that absorbs sound, and other surfaces are covered with waffle foam. The light-gage steel means you can't knock around the case without creating dents, but on the other hand you don't need a forklift to pick it up and move it. The case fans move an adequate amount of air and are just about silent.

Cons: There are 5 5.25" front-facing bays, of which 1 contains the DVD reader/writer, and there are 3 side-facing 3.5" slots in the HD cage. I'd rather have more space for 3.5" drives and less for 5.25" devices. I'd also like the i/o panel located at the top rather than close to the bottom. Unless they are less than the size of a brick or smaller, computers should sit on the floor. Why locate the i/o, power and reset buttons so close to the floor? (My solution to this oversight was to put the computer on a rack next to the desk.)

Other Thoughts: It's a really good case for a quiet PC. I look forward to the manufacturer producing another version that addresses the issues listed in the 'Cons' section.

5 out of 5 eggsSolid, quiet, very nice case, I'd get it again

Pros: Quiet, solid build. Easy to install everything including the PSU and HDDs. I've used two of these and highly recommend them.

Cons: HDD cage and drive rails aren't well thought out. They work, but if you have a loud HDD they'll hurt your noise performance. No front dust screen. No foam on the front or back.

Other Thoughts: Got this with the Rosewill Green RG530 supply and AMD Phenom II 940 and Seagate 1.5TB drive for a very quiet system and the stock AMD fan is the by far the loudest component and even then the system is as nearly silent as can be. My old 1TB WD HDD was considerably louder than the Seagate drive during operation and got banished for that reason since I use this as a home theater.

The feet are hard plastic, so for a quieter system don't put this on a hard surface.

5 out of 5 eggsI love this case

Pros: Solid construction, well thought out for my purposes. Tool-less design worked very well for me. Lots of capacity for my needs. I like the black brushed aluminum wrapping the front bezel and comprising the 5.25" and 3.5" cover plates. Best of all, it is indeed very quiet.

Cons: I am not crazy about the location of the power and reset switches at the bottom of the case. I tend to put a tower like this on the floor where these controls are harder to reach. I'd prefer smaller round buttons near the top.

Other Thoughts: I find this case to be sturdy, easy to work with, and roomy enough for any desktop I'm likely to put together. I initially installed a micro ATX mobo and some light duty components for an HTPC. After moving those components to an SFF case, I installed an EVGA ATX board with an i7 920 Nehalem and more robust ancillary components. The screw-less design allowed me to move components around easily. I found all component mountings to be quiet and secure.

4 out of 5 eggsHummer

Pros: It is quiet. My PC is on a shelf under my desk. I had a CoolerMaster Centurian which is a very well ventilated case. If fact it has so many holes in it you can hear all the fans no matter how quiet they are. It was more of a gamer case. The Sileo has padding all around the inside that muffles the fan noise quite well. The tool-less mounting works great and the case comes with plenty of mounting hardware for the motherboard. I had no alignment problems with the motherboard to rear cutouts as I have seen reported on some of the other more expensive cases out there. The power supply is "nested" in foam / neoprene so it does not transfer any vibration to the case.

Cons: I took an egg off for the problem below:
The drive cage in the bottom of the case is too rigidly mounted. When my WD 750 gig drive spun up the whole case hummed. In addition, my old Seagate 200 gig would cause a "thrumming" when reading and writing (my new Samsung 500 gig was perhaps 1/3 as loud mounted in the same location). I mounted the system drive in the 3.5 space above the drive cage where a floppy would normally go. That solved the problem. Also, the second slot under where the floppy would go is used by the front panel switches rendering it unusable. I now have to keep my WD 750 in a remote USB/ESATA dock until I can come up with a 3.5 to 5.25 adaptor. I will probably take the cage from the bottom of the case and rubber mount it in the 5.25 bay area.

Other Thoughts: These Cooler Master cases are great and possibly the best kept secret out there. If you don't want LEDs, a clear side window , a monster face or a 10" fan, then Cooler Master is the way to go.

5 out of 5 eggsSolid, Quiet Case

Pros: Foam-lined and really quiet
Nice layout inside
Large, quiet fans, front and back
Easy installation of HDD and what-not
Nice, flat black finish.

Cons: The faceplate for rear panel connections sticks into the case far enough to make it difficult to get the MB to line up with mounting holes in case.

Other Thoughts: If you're looking for a case that will show off your build's innards, this ain't it. No windows or excessive LEDs. Just simple, functional and quiet.

3 out of 5 eggs

Pros: Good quality,low price, whisper quiet!!

Cons: Beware of the 120mm fans as shipped,combined with the insulated case,they just don't pump enough air over a hot processor.

Other Thoughts: replacing the fans, would buy again.
