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.

    Wow, talk about a 180 degree perspective. I think it's the mATX and smaller that's the outlier. It's only common for OEMs but are much less common for enthusiast custom pc services or individual system builders. Look at all the cases coming out, look at the motherboards, look at the heatsink sizes, the commonality of AIO 240mm+ watercooling, and heck just look at video card sizes.

    Nonetheless I would like to see reviews of smaller cases too. However even many of the smaller ones tend to be too big, since most nowadays are designed to fit full size PSUs, video cards, 120mm fans, etc.

    I don't think the numbers support that full ATX cases with custom coolers are the anywhere close to the norm. They get deceptively large amounts of attention from a small, but very vocal group of people. Those people are buying high margin parts with much larger markups than commodity equipment so various hardware manufacturers find it worth their while to make parts for them and send them out for free to sites like AT that then review them. The end effect is that it creates something of an echo chamber-like community that may fail to notice that they actually represent a tiny faction of the computing industry's customers.

    A "gaming computer" with a single GPU on a mATX board with stock CPU cooler and sub-500W "came with the $30 dollar Rosewill case I got from NewEgg" is common. Just as commonplace are the hundreds of millions of desktops and laptops purchased based soley on the fact that they're the lowest cost system on the store shelf that end up being dragged kicking and screaming into running games with maybe a cheap GPU that won't kill the power supply stuffed into whatever expansion slot might be open. I'd argue those situations represent the average PC gamer far more accurately.

    Unfortunately, those sorts of people aren't as exciting to talk about and don't earn companies large amounts for each sale. Competitive forces in the market dictate they generate very small monetary returns that evaporate completely the moment someone picks up the phone to call for technical support or to RMA something. Without that excitement, that group is largely ignored even though they're a huge majority.

    Not to go off on a tangent, but the reason why computers aren't "fun" to me anymore is partly because the mid- to low-end gets ignored. I used to cackle gleefully in my crappy apartment, making my spouse want to leave to work on the car or something equally non-technical, as I squeezed an extra 33MHz out of my already obsolete Pentium 100 and then grumble about how it made no difference in a benchmark becase of that awful Cirrus Logic video card holding back those gobs of extra CPU power from shining through in Mechwarrior 2. That was fun stuff...back when Tom's Hardware Guide was actually run by ex-M.D. Tom himself.

    The enthusiast market is producing more stuff for the larger cases. If you look at the major brands, most of their stuff are the ATX.

    The only volume production of mATX or ITX cases are for OEMs. The usual towers from Dell, Acer are mATX while the slim towers are ITX.

    However, what you point out confirms my issue even when trying to go small: the mATX are almost as big as full ATX. The only difference is that it's either shorter (but same width and nearly same depth and mid size ATX) or it's a big square. That's the only way to fit a full size gaming GPU and full size PSU. I have several mATX and they're all like that.

    Having a shorter case doesn't help in useful space savings when it's just as fat.
    So if the mATX is still big I figure I might as well go full size which I why I'm getting rid of most of my mATX stuff. The only exception would be slim cases Antec Minuet.

    I definitely see mATX as the ideal case size these days. With mATX you can fit a large CPU cooler if you are air cooling, up to two high-end video cards, and you get 4 RAM slots. You also still get a good amount of space for cooling. Frankly the vast majority of builds would be fine with mini-ITX, but those cases tend to lose too much cooling for my tastes. On the other hand, when you are talking about mATX vs. ATX, you are really talking about extra expansion slots that basically no one needs, and a slightly smaller fan area at the front of the case (and we have gains there as well from getting rid of external bays).
    The big problem with mATX is that options (and reviews) are extremely limited, especially for enthusiast-class boards and cases. Hopefully more reviews would spur more availability.

    The front badge absolutely ruins this case.

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

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

    Is everyone purposely avoiding the topic on cooling or plain forgot?
    There is little clearance to install fans on the "bottom air intake" due to any ATX motherboard extends to the bottom of the case, Not to mention the space underneath the case is tiny due to short case feet. The top/side vent is a joke.
    Sure the glass looks good, But I will not consider building any high end system inside this case if it's going to cook the components with its "no-airflow-design"

    I suspect the bottom holes are intended as passive intake for a negative pressure design with the fans on a top mounted radiator providing the overall airflow. I'm not a fan of bottom intake without casters or really big feet. On a carpet standard tiny feet tend to sink in deep enough to plug them entirely. Not a problem on hardwood, but your case ends up acting like a vacuum cleaner and the bottom mounted filter doesn't have visible indicators when it gets filthy and clogged. Reply

    My point exactly, Also "negative pressure design" never worked well, It's more of an excuse and translate to "we messed up on the airflow design".
    I have been building computer for over 10 years, In Win never struck me as a quality case maker. One day they woke up and suddenly decided to make a case with glass side panel and put a $300 price tag on it (909) does not put them in league with companies like NZXT, Corsair, Cooler Master who knows what they are actually doing.
