Good Case for its price 6/22/2020 10:01:06 AM

Overall Review: Recently built a budget PC and decided to use this over the H510 because you get 2 of each display port and was a couple bucks cheaper. If you don’t mind a smaller case, this is a really good option.

Great Case but the Fan is Pretty Bad 6/4/2020 10:17:16 PM

Pros: -Looks awesome
-Was really easy to build in

Cons: -The case fan that comes with the case wasn't doing the job for me so I had to buy a set of fans

Overall Review: Would recommend to anyone that doesn't mind paying a little bit extra to get separate case fans. Personally, the looks of the case justify paying the extra for fans but I could see how paying extra might be a deal-breaker for some so I'll give 3 eggs instead of 4.

I really liked this case until I found a gap 5/20/2020 11:30:42 AM

Pros: this is my favorite MATX case

Cons: My case was filling with dust with 1 130 in the front and 1 120 in the back. I found a big gap under the bottom lip of the front mesh panel. It defeats the purpose of the mesh to have unfiltered air come in under the panel. Its like its there for a hand hold to pull the panel off. I looked at the Manuel and I could not see a picture to see if some thing is missing on the case I put air filter material where it was needed to close the gap.

Overall Review: I

Decent Case for size and price point. 5/19/2020 4:39:07 PM

Pros: - Decent build quality
- Good amount of space in back for Cable Management
- Nice looking case
- Detachable filters are a nice touch at this price point

Cons: - Power supply bracket unnecessary
- Needs to be a little wider/or taller for top mounted 140mm fans
- Front I/O cables need to be longer
- Bottom filter attachment is kinda bad

Overall Review: So I used this for a quick bedroom pc build. There's plenty of room to build in, and the back had a surprising amount of room for cable management. I'm use to having to kinda force the back panel onto these smaller cases to get everything to fit.

There are some small pit falls. The front I/O cables need to be longer for better cable management. They also got in the way of the front mounted fan I put in. The top 8 pin connector on the motherboard interferes with mounting a 140mm fan on top. I could also see installing a 280mm rad being annoying on either top or front. Bottom filter attachements kinda suck. They are these little rubber plugs that just push in. They don't stay too well so just heads up.

I listed it under cons but it's more of a neutral thing. The weird power supply offset bracket seems kinda unnecessary. Also the side mounted I/O was a little awkward for me due to where the pc is sitting.

Overall it's a decent case for the size, and just the cable management space in the back would make me buy it again. If you're building a budget system or a first system I'd definitely recommend it.

Great mATX case 5/18/2020 12:29:37 PM

Pros: - Seems to have pretty solid construction.
- Easy to build in
- Big enough for full-size video cards

Cons: - The magnetic dust filters are pretty lame but functional
- Side panel is thin acrylic not glass (i knew that before buying)
- Only comes with 1 fan. I recommend at least 2 more 120mm fans for the front. -- I added two more fans for the font just to push air through the case and my system runs cool.

Overall Review: Overall I would buy this case again. It was easy to build a mATX system in. I built a X570 R3 3600/RADEON 5500XT system for use as a streaming PC. After adding 2 fans to the front my system runs plenty cool even while under load while streaming 1080p/60fps. The only thing I'd say you could do to make this even remotely better would be to put a 240 AIO on the front to cool the CPU rather than just fans... but agian, my system stays well within a good temp range, so it's not necessary at all. 10/10 would recommend this case... would be even better if side panel was glass and not plastic.
