    Amazing case, probably the best bang for the buck. but the cable hole for the 24pin is ugly.

    In Win is known for their unconventional case layouts and style. And they definitely push those boundaries as far as they can. The 303 is no exception. It incorporates an attic for the psu and exhaust fans. But what makes it creative is its sideways exhaust direction.

    But that doesn't come without a few challenges. The bottom fan opening/s does have a dust filter tray. Where that becomes a bit of a headache is if you want to place (3) intake fans AND you have a full size ATX motherboard, those fans and the motherboard's lower connections will interfere with each other. You will have to get creative with some of those harnesses/connections (e.g.: front io and/or usb3 connector).

    Another design cue that does get interesting is the attic. You can fit 3 exhaust fans along the panel, but the left most fan will be blowing air directly into your PSU. As for your other two exhaust fans, even if you keep your PSU cables managed, the honeycomb designed cutouts on the back panel seems restrictive.

    Overall, I still am completely satisfied with this case and what it brought to the table. You do have to get creative with your cable management. Not only does it have a tempered glass front panel, but it also has an easy removal method which makes doing minor adjustments very easy.

    Love this case. A good case to display great components. Requires a lot of aftermarket fans because it doesn't come with any but most would buy new ones anyway

    I love this case! It's so pretty! Cable management was kind of a pain because there's not too much room in the back besides the space by the top fans. Not much room at the bottom too. Can't use my front usb 3.0. Get motherboard with usb 3.0 header on the side.

    Almost perfect.

    Fantastic looks and great value. The only issue is there is not a lot of space at the bottom for a full size ATX mobo and 3 intake fans. All of the front panel connectors and USB headers would be blocked by the fans. Run a mATX mobo and you'll have no issues.

    One of the cleanest mid tower cases you can find for a decently low price. Side mounted radiator is a big plus. Very solid construction and unique design. Oh negative is the tight space inside, making cable management difficult. Would have been nice to have an extra inch at the bottom of the case so fans wouldn't block the bottom fan headers on the motherboard

    This case is the easiest to work in, and the most attractive case I've ever owned. Modding it is a breeze, it's very sturdy, and the glass side panel is gorgeous with lights behind it. I regret nothing about this case.

    The case is huge and sleek. More room than I know what to do with. Easy access glass panel is great. The sleek design sacrifices intake vents (you're going to probably want a negative air pressure system, as the only intake vents are all at the bottom) which leaves one rear exhaust as well as the top right exhausts. Some dead space with only wires next to those exhausts though. No optical drives, but honestly who uses CDs or card readers anymore? Biggest issue for me is the 3.5 inch HDD mounts on the back of the case, the mounting brackets are awesome and easy, but depending on your SATA/power cables to each device, it's hard to get them connected without extreme bending. The drive mounts are almost flush with the case frame, so you only have like a centimeter of clearance to connect your sata power and data.

    from completed build Dark Blue

    Pros:
    - Beautiful case
    - Quite roomy to build in
    - Affordable glass case under $100
    - Pretty sturdy materials in general

    Cons:
    - No rubber grommet
    - Prefer more cutout, or at least bigger holes.
    - Negative pressure airflow
    - I/O shield is positioned kinda hard to put into

    Overall, A good case, but with flaws.
