Awesome case for the price.. almost perfect!
Was looking for a bit more "upscale" look for my next build without breaking the bank. The new "must have" as far as looks go is having a tempered glass window to display de goods. While looking for a good case that fit the bill came across this beauty. Normally InWin is more known as a builder of unique cases with outlandish aesthetics and big prices to match. Not this baby right here. Under $100 and SOLID! All thick metal construction except for the feet and side glass window. Layout is not your usual but does work pretty good. Allows room for a solid ATX build with room for components of your liking. No constraints as far as sizes go since it is pretty ample. So I'd bet it will easily fit 98% of coolers (CPU) and Graphics cards out there without worries. On that subject, it is both aircooler and also watercooler friendly. Even custom water cooling can be accommodated with ease. And will look even better as radiator mourning up top displays the business side instead of the usual side only. Also includes a graphics card Support bracket to avoid the dreaded "sag" so commonly seen nowadays with long gpu's. All in all an awesome case for the price point (got it at $69 from its usual $99). Built in solid steel with large easy to remove side glass window. Comes in black or white. Paint on it is flawless (at least on mine it was great and covered everything as it should). And again, for the price can't be beat. All other options that offer the same or about the same are all in the $130 to $200 range. So not so good in my opinion. The only 3 things I would say are needed to make this case absolutely PERFECT would be: 1. Maybe about an inch to inch and a half more clearance from bottom of case to motherboard (ATX standard). As it is motherboard ends almost flush with case bottom which makes routing cables to those parts in the bottom edge of motherboards a bit cumbersome. Same goes with mounting a second Graphics Card, fans, even radiators in the bottom spots (fans and such would cover a good portion of the board, I managed fine but a little word of caution). 2. The front ports and logo illuminate in an icy blue (Indiglo kind of) color and can be a bit too bright if you game or use computer in a dark room. Also the color although going towards a "white-ish" hue, does not color coordinate well with some combinations. If they could make this panel be brightness adjustable or even better, RGB customizable would be awesome. 3. Last but not least, adding a couple of HDMI ports in front. The next thing is VR, and most headsets would benefit greatly if these ports were accessible via front panel. Newer cards geared towards that market are bringing an extra set of HDMI outputs that can be connected to he front of the case so allows it. So having them would appeal toa lot of VR gamers looking at this case as an option.

Amazing product. Beautiful and intelligent design. Feels like a high end case with a low end price tag.
Amazing product. Beautiful and intelligent design. Feels like a high end case with a low end price tag. Pros: Beautiful sleek design with the logo, and usb ports, and power button on the front lighting up to give a unique contemporary feel. The material is high quality with a thick side panel with honey comb cut outs for exhuast and nicely tinted and tempered glass. Fans are strategically placed to maximize air flow and visual appeal. Almost all cables are hidden on the back panel which gives the inside of the case better airflow and a clean design for display. The tempered glass window is nicely added touch that gives the case a beautiful appearance that gives it a sleek effect. Case features are well thought out and include removable plates for hard drive mounts, removable dust filter at bottom, brilliant cable management and concealment with double compartment design. Cons: This particular case at this price range does not include any fans. For my particular motherboard gigabyte 970a: The third fan at the bottom nearest to the back end of the case will not fit a standard fan without smashing the cabinet wires (Front side usb, wires for power switch, HDD LED, etc.). This is a typical placement for cabinet wires on most motherboards so it might lead to some problems when fitting a 120mm or greater fan size in that last fan slot. Overall this case is perhaps worth twice its asking price and is a definite buy. I was really impressed with the overall quality and design. I really like the look of this case. Buying new fans to fill the case will add another 20-40 to the price tag depending on what you go with but most people already have fans of their own. Despite it's flaws the case is still a 5 star case that is significantly under priced.

Great case for those that like the showcase their rig besides just using it.
This is actually very easy to cable manage, however I have a fully modular power supply from EVGA and I make my own cables from scratch so I can make exactly what I need in the perfect length. This makes it super easy, even with two ssd's and two regular hdd's installed. I would highly recommend this case for someone who likes to actually look at their system instead of just shoving out of the way. I recommend this case for someone who makes their own cables and is looking to make their system unique. I do not have any of the wires to the front panel installed except for the power and reset along with the usb 3.0. Everything else can actually be unplugged and removed which makes it very clean. I only use the back panel connections . I will post photos of my system at some point in hopes it will help with someone planning a build with this. I am running an i7 7700k, gtx 1080, 16gb's of ddr4 2400 speed ram, 500gb Samsung ssd, 250gb Samsung ssd, and two Seagate hdd's, a 2tb and a 3tb. I am currently using a 750 watt power supply but I am literally almost maxing it out, so I will soon be upgrading to an 850 watt. All of these things work amazingly well in the Inwin 303. No issues with temps. I also have the i7 cooled with a H80i AIO.

Its great. Please read about Hard drive
Loads of room to work with. Wiring management could be better. Material quality is fantastic. Love the quick panel release. Great job on the 303 inwin! I love it One thing on the hard drive slots. You cant use a 90 degree data port. Has to be flat. I only had 90 degree angles

Great case, getting ready to by a 3rd 303 case.
I have bought 2 of these cases. One white and one black. My current build is in the black case. Built it for a water cooled gaming rig using an IAO cooler. The quality of the case is awesome for the price. Only draw back is the lack of grommets but that is an easy mod. This is a great case for modders. I have had this case apart and modded both cases. I ended up hydrodipping the MOBO tray and upper chamber of my first case and modded the color of the front panel of both cases. A lot of room for a custom res or two and a pump. They don't advertise it but I have seen people put 360 radiators in the bottom so some do fit. The bottom fans are a tight fit with the front panel connectors so if you not planing on running 2 video cards a Micro ATX or a Mini ITX will fit better. I am about to order a 3rd case in white for a future build for the wife. Running 5 PWM fans and a IAO cooler pump and this thing is silent. Have not played any demanding games yet to test the noise but so far I love the case. Do wish the glass was not tinted though as the inside of my PC looks nice

High quality case for a low price.
This is a great case for anyone who wants a show peace but doesnt have the cash to drop on a super expensive case. Its very easy to build in and the build quality is great, the case while empty is about 25 lbs so it will be rather heavey when your system is installed. Cable management is a breeze as well due to the psu shroud at the top. Fan instaltion can be a bit of a chore on the top mounts if you run a push pull setup on a radiator like I do, but once you figure it out the mount is solid. Airflow is great as well, 2 of the 3 intake fans provide my gpu with fresh air at all times and keep it under 65C under full load when gaming on high or ultra settings in newer games. For a visual review Hardware Canucks and Gamers Nexus have both done great reviews on this case and I reccomend checking them out.

the Case is sturdy and looks good but there are two problems
the Case is sturdy and looks good but there are two problems. The PSU sits in a cage at the top. In spot are 3 fan mounts, going right across the PSU fan, so pushing air though the top may not be as good compared to other cases with a bottom mounted PSU. The motherboard also sits at the case so if you wanted to have 3 fans on the bottom along with other PCI-E cards (NIC, Sound, GPU, Etc.) You will have to either give up 2 fans or squish everything together. TLDR; Not very good for expansion but looks nice.

Amazing case, minor cons depending on the owner.
Wow, what a great case! There is room for an atx sized motherboard and smaller, not sure about EATX as the desc says, as my mobo almost touches the bottom of the case. There are six fan slots, as well as using ur psu for exhaust. It beautiful and well made. Cable management is a bit rough as there arnt alot of cable ties. Routing is straight forward and not too difficult. Once you install bottom fans you will not have access to mobo headers sp make sure you plug those in before you put in your bottom fans. Other than that, enjoy the well thought out case! Temps are also great! Heat dissipation is amazing even when using air cooling. My dark rock 3 cooler fits just fine. I have it vertical in the case to blow all the hot air up and out of the case. I wouldnt recommend blower style gpus for this case, rather ones that blow hot air into the case upward.
