Exquisitely Modest Aesthetic Design

The IN WIN team presents the 303, a simple, yet elegant computer chassis crafted from steel and tempered glass. The distinctively clean front panel is complemented with a bright LED design to balance the overall appearance.

Radiant Luminosity

The IN WIN logo is highlighted “Neon” as well as the lucent stripped I/O front panel. These gorgeous LEDs also have the purpose of indicating when the PC is activated.

Accelerated Tool-less Design

In Win has set a standard for being an innovative computer hardware company. Mission accomplished with the 303 since it has perfected a tool-less design by being able to remove the beautiful 3mm tempered glass side panel by just pressing the handle.

User Friendly Dust Filter

This easily accessible dust filter has an embedded design for quick removal. It’s conveniently located on the bottom, and removing dust has never been easier.

Versatile Cooling Options

Overall, the 303 can accommodate two radiators (top and rear) and three fans at the bottom providing users with a well-cooled rig. The cool air intakes from the bottom creates efficient airflow for quick heat dissipation.

In Win's Attention to Detail

The 303 is constructed with 1.2mm SECC, supports 2.5”and 3.5” drive bays, and its separate PSU chamber provides an ideal climate without interfering with the motherboard and graphics card area. The specialized GPU holder can provide extra support to graphics cards. Yet another detail IN WIN oversees and manufactures to make PC building much easier.

Pretty good, not the best 10/29/2019 10:39:52 PM

Pros: - Open design for easy building
- Good amount of forward facing USB ports
- Looks great with the giant glass panel

Cons: - Airflow is not optimal
- USB quality is not up to snuff
- Only one dust filter

Overall Review: This is, in my opinion, one of the best looking cases out there, and while I'd still recommend this case to people building a PC I would have some warnings first:

1. The glass panel is set away from the case (no seals) and thus if you have a negative air pressure cooling configuration your case WILL be packed with dust.

2. The USB 2.0 ports were poorly made, and became unusable after a few times plugging things into them due to the pins bending. Thankfully, the USB 3.0 ports are of better quality and held up just fine.

Solid 4/12/2019 8:22:46 AM

Pros: Looks great.
Tempered glass is slick and pretty, easy mechanism to get it off.
Catching thumbscrews for the back panel is very appreciated
Thick steel
Good rgb FPC
No sharp edges

Cons: No fan included what so ever, a must for this kind of case
No rubber gromets for cable pass through
Would have like to have one at the to of the motherboard for the cpu power

Overall Review: Lack of fan is why an egg was removed.

Fun to look at, not to live in 7/5/2018 1:49:10 PM

Pros: Aesthetically, this case is amazing. The outward-facing fan mount at the top is a unique way to showcase your build, and the large open chamber beneath it allows plenty of room for creativity.

Cons: Unfortunately, aesthetics are all this case has going for it. The HDD mounts in the back are kind of a pain to route cables around, there aren't enough well-located holes for cable management into the main chamber, and overall cable management leaves a bit to be desired. Plus, the main chamber is awkwardly short, such that an ATX motherboard is nearly touching the top and bottom - as a result, I couldn't fit in the reservoir I bought for this case (though I admit that is my fault for not checking measurements).

However, the main thing about this case that's making me dump it is the airflow. With the only intake location at the bottom of the case, your GPU will block the air from circulating quickly, which causes a lot of heat to build up inside the case. In addition, if you're using the top 3 fan mounts as exhaust through a radiator, the air will not effectively exit the chamber behind the fans, and as a result, more hot air gets trapped there. My custom loop sees starting max temperatures around 55C on the CPU and 50C on GPU, but due to the hot air being trapped there, after an hour or so, my max temperatures are up to 70+ on the CPU and around 60 on the GPU. If I remove the front and back panels, this rise does not happen.

Overall Review: If you're going for a simple build, this case will make it look good. But if you intend to overclock, watercool, or really make any use of the top 3 fan mounts, frankly I'd say look elsewhere. The Define R6, PC-O11 Dynamic, or the Alpha 330 are all equally beautiful cases with drastically better designs.

Not really high airflow? 1/10/2018 9:20:00 AM

Pros: - Nice simple design, minimalist
- Extremely efficient for hiding cables.

Cons: - There is almost NO airflow at all. 1 Exhaust fan out the back.
- No Front Vent to mount any fans.
- Glass panel only held in at the top by two clips, the alignment was a bit off near the ends.

Overall Review: I bought a pre-built system that used this case and It looks great both in the picture and in person but if you are going for a high end system, this case isn't for you. There is no room or place to mount any Top, Side, Front Fans. This is NOT a high air flow system. 40C CPU temp while idle with side panels on. Once I took them off, it went down to 26C. There are holes for mounting bottom fans but just NOT enough room to actually mount them when you're running SLI or Crossfire. There is a single exhaust fan out back and that is definitely not enough for the company to claim HIGH AIRFLOW. If I could return this case, I would and op for a bigger case or one with actual opening on the front panel.

These are beautiful case's. 12/22/2017 12:54:50 AM

Pros: The RGB hooked right up to my $5 remote so i didn't need to load the board B/S and i could also double wire it as there was 2 bridged headers. One case is wired only to wires 12v and #2 (red) Was a red build.
Came with enough screws and such.
It looks classy and is a top notch case.
Wide enough to hold a liquid cooled video card with zero issues.

Cons: Rebate form was posted a tad late for me. I bought 3 or 4 of these i wish i would of known sooner.

Yea if that's my biggest complaint i got problems right.

Overall Review: There is really not much work to do to on this case. Its big enough to hold everything right off the bat.
CPU RAD goes upstairs on 2x PP fans. RGB strips fit nicely.

Beautiful Large Heavy Case 12/3/2017 10:37:50 PM

Pros: Lotza of room,
Bottom is vented
No wasted room on antiquated OD bays
Sturdy- very Sturdy
Wide enough to hold a liquid cooled card.

An RGB controller and WIFI remote with 4 strings of LED's is under $10 (auction site) an can- will plug right into this if your motherboard has no RGB header and your already bought fans and led strips

Cons: My only negative point could of been avoided wit better QC- probably anyway.
The RGB headers were broke off on-inside the connectors. That was a fiasco to fix.

My unit showed up and looked like it was stuck under a truck somewhere. Side of the box was torn open, it was greasy. Packing thingy s were broke up and the case was kinda bouncing around inside the box. Driver didn't show it any love either thumping it to the ground and dragging to my door with one hand.

Overall Review: My MSI board was advertised as having "Mystic Light" - well that turned out to be a lie. So anyway, i put 120 AIO upstairs far right. Had to make the cutout a tad bigger- no big deal. When your video card ships, use that finger (contact) protector over any freshly cut edges if you think you need grommets or such. I did P/P on those fans up there on that.

My finished build with liquid coolers weighed in at 49Lbs.

I would absolutely recommend this case. I am here to buy 2 more right now just having an issue on color schematics

heavy steel box 11/29/2017 3:06:47 PM

Pros: Big , nice airflow if you populate all 7 fan mounts.

Cons: Rgb won't work unless you have a 2017 mobo. It has a 4 pin female header with a male adapter if you want to daisy chain.

Overall Review: So the difference between this and the normal 303 besides lights and type C, is the inclusion of 140 mm fan mounts as I takes but the top 3 are still 120mm... this case no joke is heavy, 24 ish without anything inside. If you are wondering about the side honey comb exhaust, it actually works if you have decent fans, for there are no fans including.

Fun fact: with the zip ties included you can tightly fit 4 120mm fans, same with the bottom intakes

reception In Win 303 White 11/11/2017 9:11:03 AM

Pros: - thanks to Newegg, delivery was fast (~ 5 days)
- the tower is a good product, nice, heavy and hard build

Cons: - the tower has only a simply bag around, with polyester boxes on 8 corners, plus the carton around!!
- no film on the glass door ?????
It seems to be the standard for In Win...

Overall Review: This tower has all you need for a good setup, on all ways.
But protection for delivery gives you the feeling like... In Win doesn't put so much money on final boxing. Cause one of the most enjoyable thing for gamer is unboxing new parts of your new setup.
