The Interior of the In Win 303

A fine detail that one can notice once the side panels are removed is the foam strip that In Win applied on the interior edges of the side panels. These strips seal the space between the side panel and the case, preventing scratches and cancelling certain possible rattling/vibration noises.

The removal of the case’s panels reveals a peculiar interior, with the PSU compartment above the motherboard tray but taking only the right half of the space. There are no cages for the drives or other items, leaving the interior looking very plain and empty. The metal frame that separates the PSU compartment from the rest of the case has slots for up to three 120 mm fans or an equivalent liquid cooling radiator. These fans will be forcing air out mostly from the right side panel, but some of the air flow will be getting pushed behind the motherboard’s tray.

The motherboard tray, the PSU compartment frame and the expansion card covers are black, whereas every exterior panel of the case is white. There is a fair opening on the motherboard tray for the installation of aftermarket CPU coolers that should be large enough for any ATX motherboard. There are openings to the top and right side of the motherboard for the cables, as well as two more openings below the motherboard in case a Micro ATX or Mini ITX motherboard is used. None of these openings have rubber grommets.

There are two slots for 3.5”/2.5” drives to the right side of the case, behind the motherboard. The small metallic drive trays are removable and one 3.5” or 2.5” drive can be installed on each of them using the supplied screws.

Two more drive trays can be found inside the system area, next to the rail where the large expansion card optional support braces can be attached. These trays can only accommodate 2.5” drives.

For the means of this review, we installed a Corsair AX760i with the red cable set, for strong visual contrast. The AX760i easily fits inside the PSU compartment of the In Win 303, with plenty of room for managing the cables. The excessive 32 mm clearance behind the motherboard tray makes cable management very easy. Note however that the PSU is installed with its fan facing inside the system, forcing it to draw air from the inside of the system area rather than from the outside of the case. Its position will also have its fan right in front the first 120 mm fan, if one is installed. This can significantly increase the operational temperature of the PSU if a radiator is installed there, as the thermal energy from the radiator will be getting released right in front of its intake.

The system area of the In Win 303 is roomy but narrow. There is virtually no clearance between the motherboard and the bottom of the case with an ATX motherboard installed, preventing the installation of a liquid cooling radiator at the bottom of the case. If a Micro ATX or Mini ITX motherboard is installed however, the use of a radiator up to 360 mm long is very possible. A radiator up to 360 mm long can be installed on the PSU compartment frame and a small 120 mm radiator can be installed on the rear panel of the 303. Liquid cooling may be necessary for an advanced system, as the clearance for air coolers is only 160 mm, ruling out many top-tier air coolers. Cards of virtually any length can be installed, but we strongly recommend cards up to 350 mm long, as longer cards will block the cable openings and the 2.5” drive trays.

    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

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