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.

    I'd not call a case "minimalist" if it sports a gaudy logo with bright, blue LEDs on the front panel.

    "Minimalist" now seems to mean "no external drive bays".

    I built a PC out of an Inwin case awhile back that had a similar backlit logo and button array. To my pleasant surprise, the logo can be removed and changed. The guy I built it for ended up using a clear piece of 3M film and a silver sharpie to inscribe his gaming handle. It looked really good and is a hit at LAN parties, everyone can find him without looking for his placard in the dark...

    I agree with this. The design is "simplistic", and even that is an stretch. It's just a boxy and "clean" layout.

    That being said, I like it a lot, but the front LED feels like unnecessary bling to an otherwise great looking case.

    spray paint will fix that logo window easy enough.

    I think you are confusing "minimalist" with a simplistic, understated, or muted design aesthetic. In this case, minimalist is referring to the fact that there are no external drive bays, drive cages, fans, minimal HDD/SDD mounts, and little else in the way of extra features.

    Of course, their own description labels this as a prominent feature: "Exquisitely Modest Aesthetic Design". I might be inclined to agree if they didn't have the "gaudy" logo front and center. The fact that it lights up puts a permanent axe in the "modest" description.

    Instead of wasting time arguing what is minimalist what is not, You guys are forgetting one of the main purposes of the computer case: Providing good airflow to cool your precious components. And I simply don't see it's possible with this case regardless what kind of fan configuration you use.
    The price is not bad, But it has no stock cooling so you have to invest in 2-4 case fans that can seriously push some air which this case desperately needs. I have seen lots of In-Win cases, All looks no airflow (hello, 805, 901, 909...)

    I actually have this case, I'm running 7 EK Vardar fans, with 2x360mm rads... The cooling is great.

    Could it be 5 degree's cooler in a case with better airflow? Yes most definitely.

    The real question is does it make a real world difference. Overclocked and under load it doesn't hit 70c on the GPU or Processor - plus it looks stunning. (Apart from the retarded blue logo, which I will get round to dismantling at some point.)
  • Aerodrifting - Thursday, October 13, 2016 - link

    And how much does a 2 x 360mm rad custom liquid cooling cost?

    Don't forget about the honeycomb thing on the side. Very unminimalistic.
