3 out of 5 eggsWorks, but not impressed

Pros: Its a mATX case
3 x 3.5" drive bays
1x 5.25" drive bay
350 watt power supply

Standard TFX power supply - I've seen comments that it is non-standard, TFX power supplies are standard. If the PSU fails, then you can order a replacement just about anywhere.

Cons: Didn't come with a shroud as advertised, it did however come with a case fan. . I would have preferred the shroud as I purchased a case fan. They really need to update the specs on this product page to include that detail.

Power supply has 2 SATA power connectors, 1 Molex power connector, 2 - 4 pin power connector, and the systemboard power interface.

Bottom 3.5 inch drive position cannot be used for a 3.5 inch drive with the MSI systemboard I used. The metal edges of the drive cage would have cut off the USB 3.0 headers on the systemboard, I would have preferred a 2.5" drive bay there to allow the extra inch or so for any systemboard cables that hook in on the side. I can't use this spot for a 3.5 drive, although I could use it for an SSD just fine. The edge of the drive cage lands right next to the edge of the systemboard. I just bent the drive cage back to allow the USB 3 headers.

Other Thoughts: Overall this is a good case, its sturdy, without too many sharp edges, and packs a lot of stuff into the mATX form factor.

The missing shroud/added case fan details should be reflected on the product page.

i5-4590S, MSI H97 mATX systemboard, an inwin BL641 case, Samsung SSD, and 16 GB of memory, running windows 8.1. . this thing boots up FAST and runs quiet.

Manufacturer Response:


We are sorry for the inconvenience that you have experienced. Please kindly contact our customer service department at 909-348-0588 x 741 or email us at We will provide you a free new shroud as soon as we can. We will also inform Newegg to update their product information.
Thank you very much.

Pros: Awesome case, sturdy yadda yadda

Cons: Item description states that there are 4 USB 2.0 ports...not so. 2 x 2.0 ports and 2 x 3.0 ports. As such, the second two are useless without a 3.0 connection on the MB. Bad description and wrong photos.

Manufacturer Response:

Dear Sir or Madam,

4 out of 5 eggsA Labor of love, but worth the effort

Pros: Sturdy, modular design, easy to pull apart.
Nice clean look
No sharp edges, just enough room to fit decent M/C hardware
Perfect form factor for media center case - SFF PSU included

Cons: None really, just that I had to remove a part of the CPU Fan shroud in order to clear my CPU fan. Be prepared to take the whole thing apart if you need to make any changes, even to re-seat a cable.

Other Thoughts: It took me about 2 1/2 hours to assemble this thing and get the cable routing right; it takes about 1 hour to assemble a typical build, but it was well worth it.

5 out of 5 eggsGood case but be Careful

Pros: Great little case to replace work desktops to tabletops.

Cons: Sharp edges where the motherboard plate goes. I guess now I can say I bleed for my job. I'm still going to buy more. I'll just be more careful.

Other Thoughts: Smoother edges would be great other than that it works great. Or they could throw in a pair of leather gloves.

4 out of 5 eggsPretty good design

Pros: I have purchased over twenty of these cases so far. Replacing computers is an ongoing task at my job. These cases have replaced the old, large cases and make my job easier in design. They also provide sufficient power for a Pentium G2020, 4GB ram, 32GB ssd build for every normal workstation at my job.

Cons: At first installing an ssd can be difficult because of the funtion of the plastic/metal holders, but once you get it, it works.

Other Thoughts: Product recommended. I have been in the process of replacing all of the normal workstations at my job for months now (we have a lot) and I'm getting rid of the old cases and power supplies (these include a power supply each) with these and give staff more room at their desks.

1 out of 5 eggsBad quality PSU

Pros: The case is robust

5 out of 5 eggsIN WIN BL641.300TBL

Pros: Very small size, great for a small footprint. Just slightly bigger than the Foxconn Mini-ITX case I replaced. Well built. I do stand mine up upside down so the case fan, which I use as an exhaust fan, pulls the hot air out the top and I can see into the case thru the CPU vent holes.

Cons: Didn't come with a case fan. For the price of the case it should have.

Other Thoughts: Power supply works good and appears to have all the RF filtering in-place. I did have to open the PS up and insert a 56 ohm 1 watt resistor in the red fan power lead to slow the fan down to a respectable speed.

5 out of 5 eggsGreat Case, Company & Service

Pros: - great value
- great build quality
- wonderful, friendly customer service

Cons: *none really especially if you take the price under consideration.

Other Thoughts: Apart from being able to build my first computer project without trouble, I noticed I didn't have the side fan as pictured on the manufacturer's website. I called them but realized that it was actually labeled "optional" on their site. Despite it being my fault, I was nevertheless sent by the company the fan that I was missing. I do not want to put the company on the spot or anything nor do I guarantee that they will do you the same favor but this service, and the customer service person's politeness needs recognition =)

5 out of 5 eggs

Pros: good airflow
small and sturdy
looks good
matte part of the faceplate matches the CD drives I got perfectly

Cons: Cable management was a bit difficult, but once a computer is built, that doesn't matter anymore as long as airflow is still good.

Didn't come with a case fan on the side. I expected it to but that's what I get for not reading thoroughly enough. Luckily I already had a few spare of the right size for that.

The cpu duct lined up with my cpu fan, but the ram I bought has heat sink fins that stick up a bit so I couldn't use it.

Other Thoughts: I am switching to using this case for computers I build for the office from now on.
