no front door panel, quiet, cheap, lots of room
PSU space a bit narrow, front panel tight, cable management
As noted on most reviews find on the internet, the case is quiet and cheap, exactly what I was looking for in a case. It also has nothing flashy on the outside which i consider a plus. a looks slick in it's simple way.
there is lots of room inside, and everything is a breeze to install.
just as a mention for installing the power supply. it does come with longer screws to accommodate the padding, the only real annoyance is having to squeeze it in.
The front panel needs quite a bit of force to pull off, a bit too much for me to be comfortable with.
other than that, great case! I definitely recommend it.

Looks, construction, low noise.
Acoustic dampening around the powersupply makes for a VERY tight fit.
Only one real weakness at this price - it was a pain to get in the powersupply. It may just have been the specific PSU I used (BFG 550GS) but I would imagine most PSU's with a fan mounted on the bottom would make it difficult. I had to bend the lower PSU holder bracket down ever so slightly to get the PSU in. Otherwise I would have mangled the fan grill.

Other than that, this is a quality case. I wouldn't use it (with the stock fans at least) with any high end video card since it is definitely not an air-flow oriented case. But for an office PC, HTPC, or a day-to-day PC, or even casual gamer, it would be great.

Solid construction, nice design and layout, nice features, decent price.

I actually give it a 4.5/5, mainly because of the PSU issue and not having fan filters. (Used drier sheets work great though!)

Attention paid to sound dampening.
Bit cheap construction.
Sound dampening foam's effectiveness is questionable.
Overall an excellent case for the money. The fans are very quiet and after modding a PSU to 5V, the box is near silent with only the case and PSU fans running. I think the foam helps a little bit but not as much as hoped. The quality of my Lian Li PC-B25 is much higher, so the price of the Sileo is warranted. Still I highly recommend this case for any silent computing enthusiast.

Comment: Coolermaster isn't a name that comes to mind when we think about quiet computing, so to be honest, we weren't expecting much. We are pleased to report that the Sileo 500 is a humble, affordable, and most importantly of all, quiet case. It doesn't stack up to a top silent case like the An

Comment: The Coolermaster Sileo 500 is a very well made and decent chassis for anyone who cherish their silence. Cooling performance is OK, considering there are only 2 x 120mm silent, low rpm fans to cool the entire chassis.
