    Beautiful, sturdy, clean, spacious, and beginner friendly. A genuinely well thought out case. The strengths of this case far outweigh the minor flaws and it is definitely a strong competitor to the Phanteks P400 & Enthoo Pro M, NZXT S340, Fractal Define S and other cases found at the 70$ price point.

    Holy cow where do I start, Amazing looks, great cable management, just amazing.

    But, 240mm coolers where a little confusing to install, but me and my dad figured it out ;)

    I would recommend this case to anyone who asks

    Can't say enough about how beautiful this thing is. Well worth it for the price and features. You can't go wrong here.

    from completed build OREO- A PC build for my mate

    What a dream to work in. Cable management was quite easy, there are plenty of tie-down points and routing holes for cables. I wish that there were grommets for the routing holes, but costs have to be cut somewhere. There are many options as to where you can mount an SSD, which I think is a nice touch. The basement for the power supply is lovely and helps hide all the PSU cables; a great addition for a budget case. I haven't worked in many cases, but this is the best one I've worked in so far, and sets the bar for budget cases. 10/10 has all the features someone would want in their first PC. Can't recommend enough.

    I love the case's look and it was an absolute joy to work in, just could have better airflow. ( When I got it it was $55)

    This case it much more roomy than my previous pc, with plenty of cable management space. There is a shortage of places for fans up top, but I only need 2 fans to run my rig.

    Great case! very stylish. Only gripes are its not completely white (accessories and back are black) and could use a bit more cable management tweaks like a bit more space in the back and some rubber grommits, but other than that, I love it!

    from completed build Yesteryear

    I'd give this case 3.5 stars. It was an amazon prime deal and appealed to my wifes atheistic. However the issue with the whole lineup of these cases is the front panel being solid. The cut outs for air intake via the sides are not sufficient to keep even a basic pc cool. I could measure a decent temp drop by taking the panel off.

    Pros: Removable psu shroud for easy install and cable management. Lots of cable tie down points to make cable management easier. Does support three 120 mm fans in the front.

    Cons: The front panel chokes the case and there are no other intake points. There is also only rear exhaust as the top panel is solid and non removable.

    from completed build First Build : Dark Ice

    This is an easy to build in fully featured case. It is easy to see that cable management was well thought out with dozens of tie down slots all over, large cutouts, and plenty of room behind the motherboard.

    I generally liked the PSU shroud as it helped with cleaner look, but since it was open ended it didn't completely keep cables out of sight.

    Solid case wasn't to difficult to work in, but not as roomy as I expected and propobly inferior to other cases at its budget.
