In Win is one of the oldest manufacturers of PC cases and power supply units. The company was founded in 1985 and they recently celebrated their 30th anniversary. Unlike most other companies, In Win has remained almost exclusively focused on the design and marketing of PC cases and PSUs rather than trying to diversify into other areas of the market. Today In Win is offering one of the most comprehensive selections of cases, ranging from low-cost towers to entirely unique designs.


It's been a while since we had a deep look at an In Win design. In Win supplied us with the 303, one of their most recent ATX tower cases. In Win promotes the 303 as a combination of a unique aesthetic with practical design and a reasonable price tag. On paper, the 303 does appear to be a very interesting product. We shall have a closer look at its quality and features, as well as assess its thermal performance in this review.

Packaging & Bundle

We received one of the very first samples of the 303 and In Win did not have the retail package ready at the time, so we cannot comment on it. We did receive the full retail bundle though and it was unsurprisingly basic. The company supplies only a typical manual, the required mounting hardware, support braces for the heavy expansion cards and ten cable ties.

    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.

    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.

    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.

    need edit!!! Then I read them when I got home.

    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!

    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.

    The front badge absolutely ruins this case.

    My loge for the Anidees AI-Crystal lives on! ( )

    Ugh, that cream color harkens back to a time of sickeningly ugly cases.

    The interior and glass looks fantastic. The rest of the exterior looks like absolute dog shit.
