This is one of the best cases in this price range. You get a side window, two pre-installed fans, pre-installed standoffs, and four USB ports on the front panel.

If you're building in this, make sure to get a semi/fully modular PSU, cable management could be tricky.

very good case, and i like the looks, but i scratched my side panel window by cleaning it with a paper towel. :(

For the price, I don't think this case can be beat. It has very good cable management options for such an inexpensive case, it looks nice, and comes with the necessary fans. I could take or leave the plexi side panel but for what I paid ($10 after rebate) I am very happy. Much better than any other inexpensive case I have used.

Pretty good budget case.

It has a m a z i n g cable management for the price. Plenty of space behind the side panel, cutouts next to the motherboard, giant cutout near the front, cpu power cutout, everything you'd need. Comes with 2 fans with the 120mm having both 3pin and molex, and room for 3 3.25" drives (one ontop of / inside 5.25" bay) and 1 2.5" drive (more if you can hide them somewhere.)

Downsides. - Completely choked front intake, next to no air at all. - Snap off PCIe brackets except for one, but it's cheap so eh whatever. - You need to dremel off the side HDD bracket if you want to use a video card larger than 8 inches and PCIe slot wide.

Otherwise though, on a budget for a small low power system, GET THIS! You can cable manage freaking OEM power supplies in this case, lol!

One of the best Micro ATX cases out there for a cheap price.


  • Perfect cutouts for cable routing and managing psu cables. Decent space for non modular power supply cables.

  • Clear side panel (for showing off your awesomazing hardware)

  • Comes with 2 case fans. One intake and one outtak.. "exhaust fan"

  • USB 3.0 ports!! (there is 2) plus 2 USB 2.0 ports

  • Left side panel has extra space for cables (yes it matters)

  • Rubber feet

  • Good build quality, even better than some cases $10-20 more expensive tha this one.


  • Rosewill's quality control or something like that

  • My case arrived with two oily finger prints on the front panel which was really noticable and impossible to remove without soap + water.

  • One screw hole for the Power Supply mount had a little metal lip that had to be bent as I screw the power supply (minor issue).

  • Thumb screws for the side panel for were so tight and hard to unscrew out of the box.

  • Small rear exhaust fan 80 or 92mm. I wish it had space for at least a 120mm fan mount.

Overall this is a great case if you could get it for around $25 USD or $35 CAD

Good case for little money. Got for 11 dollars from Newegg (20 - 10 rebate) Enough room for cable management. There are two pre-installed fans though front one has little room to suck air. Side transparent panel is cool. Only concern is that HDD mount has no vibration cancellation so it amplifies its noise under use.

I posted this build just so I can comment on the case and yeah not a big fan. It's cheap and functional but the airflow on this case is crap. The fan has to suck up air through a hole in the front bottom of the case and it's not great. I think this PC is the loudest out of the bunch of built PC by yours truly. The acrylic window is a nice touch though. Not a fan of trying to fit in a regular sized GPU in this case. Short GPUs are fine.

from completed build As Cheap as Gameable

Cheap as dirt. Looks decent from the side, but don't expect much here. The panels are flimsy as can be. The airflow is garbage and with poor cable management, you're going to end up covering the front intake fan. You can definitely do better at this price range by going with one of DIYPC's offerings. However, if you're like me and have to have small, then this is about as small as you get with the mATX form factor.

from completed build Perfectly Mediocre Gaming Rig

Nice case. I like the aesthetics. Default back and front fans can get a little bit noisy under load. By the way, the side window doesn't actually open. And the front has no ventilation holes for intake; the front fan just pushes inside air to the back.

bootrec 10 points 10 months ago

Have to check measurements before you buy this case and compare with your video card, PSU, CPU cooler. It's simplistic in design but good quality build.
