The Exterior of the In Win 303

The In Win 303 visually is very simple, perhaps even excessively minimalistic. All of the case’s panels are metal and only the side panels are removable. The front and top panel of the case are entirely flat, with just the I/O ports, buttons and an illuminated panel with the company’s logo at the front of the case. We received the white version of the 303 that has white exterior metal panels, with the exception of the smoked tempered glass door (real glass, not acrylic) left side panel. The paint is very well applied. Note however that the white paint of the 303 is not perfect white or snow white, but leans slightly towards the floral white hue.

11.2 oz soda can added as a size reference.

Measuring 50 cm tall, 21.5 cm wide and 48 cm deep (19.7 × 8.5 × 18.9 in), the In Win 303 is not small for an ATX tower case. It has a volume of 51.6 liters, almost identical to that of an advanced ATX case but with optical drive bays, the Corsair 450D (also 51.6 liters). It is larger than the Zalman Z9 Neo (48.4 liters) and NZXT S340 (38.4 liters), which are relatively low-cost ATX tower cases, but it also is very heavy, tipping the scales at 11.2 kg, making it at least 50% heavier than typical ATX cases. A portion of that will be the glass panel.

The front I/O ports and buttons can be found across the right side of the front panel. A large square Power On button can be seen at the top corner of the front panel, followed by a small square reset button. An illuminated panel with the company logo separates the I/O ports from the two buttons. Two USB 2.0 ports, 3.5 mm audio jacks and two USB 3.0 ports can be seen in line under the illuminated panel. These six ports also have illuminated surrounds that will stay constantly lit as long as the system is powered on.


A look at the rear of the In Win 303 case hints that the interior design will be more or less atypical. The system area is at the bottom of the case and the PSU compartment is above it, resembling the classic ATX configuration. However, the PSU is mounted vertically, drawing air in from the right side panel of the case. One slot for a 120 mm fan can also be seen.

The bottom of the case serves as its main air intake. The clearance between the case and the surface is barely adequate, with the 303 standing on two large but short rectangular feet. A large nylon filters covers the entire intake, which can be removed by pulling it from the side of the case. We found this to be an excellent design choice, as the filter can be easily accessed from the side of the case. Considering the length of these filters, removal from the rear of the case is typically problematic and inconvenient, making this design a bit nicer.

    Perhaps you can remove that logo and replace it with a personal touch.
    But I also don't like that color, ruins the thing you could have achieved with the tempered glass, could have looked so much fancier. Looks like it is more geared to the Korean market or something.

    You should test your testing methodology to include both stock configuration--in this case, no fans--and optimal configuration i.e. with fans and with water cooling, since that's what is was made for. I'm pretty sure no one is going to run it fanless.

    I took at look at this case at the store and the first thing I noticed was that it was very heavy. I didn't know that the logo and ports lit up though, so it's good you showed that.

    At this point I blame the case OEMs for sending cases like this in for review. You and I aren't the only people who've raised the issue over the years in comments; but E. Fylladitakis appears uninterested in changing his testing methodology to make it not drag cases whose design is built around ventilation generated by other components fans (eg the radiator in this case, or the cpu cooler and GPU blower in compact mITX cases) instead of fans bundled in with the case itself.

    Exactly, this case is not and never was intended to be a passive case, and testing it as such is ridiculous.

    It would be akin to testing a thermalright cooler with no fans attached, since Tr doesn't ship fans with their coolers. Or testing a 240mm rad with no fans or water pump attached.

    Right now, this review tells us NOTHING about how the 303 would fare as a normal or water-cooled case. For all we know, it could be excellent, or it could have some weird airflow quirk that kills its thermal performance in the real world.

    Looks like a nice sturdy & cheap case.

    Oh has anyone noticed that DT is alive again? I know a lot of us are old DT readers before it went tits up.

    And yet its worse than before, mixing off base articles now with obvious paid filler content like a bunch of fake supplements. Reply

    I was at work so I didn't get a chance to look much at it. I was looking for a site on my favorites and saw it was still saved so I clicked just to see if the site was up. To my surprise there were new articles. Then I read them. Holy fricken run on sentence. Every article was in ESL or ETL. Reply

    I saw the black version of this case @ local Micro Center here in Columbus, Ohio. Decided to buy it yesterday actually. It is absolutely awesome, and it was just $84! Reply

    I'd like to see future reviews focus on mATX and smaller designs. These larger cases are uncommon outliers rather than mainstream so I don't think they're very relevant to most system builders and personal computer owners in the present day. Reply
