★★★★★I like
I had trouble with the wires at the back since I'm not too great at chaining it. Lol but it came turned out great. Helped my cousin upgrade his rig. Ryzen 3 3100 + rtx 2060 + 16gb ddr4 rams to a ryzen 7 5700x + rx 9060xt 16gb + 32gb ddr4 rams. So much better and cleaner. This will last him for a while. Happy with the case and build. The price is cheap and has 6 built in fans. Recommend the case to others for a M-ATX build.

★★★★★Buy it, you can't go wrong with it
The media could not be loaded. https://m.media-amazon.com/images/I/H1aaQ3ZzY-L.mp4 https://m.media-amazon.com/images/I/81CHuD58TaL._SY256.jpg This is the first time I've built a compact Micro ATX PC and let me you, this case made it way easier than it had any right to. Do keep in mind that you are getting what you pay for. The quality is definitely not poor, but it's does not look or feel cheap in the places it matters. This thing offers so much space to cram whatever PSU cables or sata cables you need to. Everything you do in the back panel is nearly invisible to what you'll see on the other side. Don't bother replacing the fans if you're on a budget! These things run shockingly quiet and if you're looking for RGB then you've already got a good set! I've got no complaints with these. Overall this thing is great. Are there better ones in the same price? Absolutely. This is all preference based. I chose this case due to it already having 6 fans and a really sleek design! I'm was really happy to see Antec still making really good cases! Also this thing has built in GPU support, that was such a nice surprise cause I had no idea it did.

★★★★Good quality, excellent hardware support, easy to work inside and fairly priced.
The Antec Flux M is a nice micro-ATX motherboard with a nice air flow design, a clean interior and front-mounted PSU compartment. Besides the power and reset buttons, there is a USB-A port, a USB-C ports and audio jack on the front. I was looking for the Phanteks XT M3 for this PC build, which is a very similar unit. It was not available, so I went with this unit and it was a pleasure to build on it. There was plenty of openings around the motherboard to route cables and also space on the rear to hide them. There are six 120mm fans included, three of them black and three are ARGB fans. The case has a toolless glass side panel and there are magnetic dust filters on top and bottom of the case. I removed the top air filter, since it exhausts air from the radiator and it works better without it. This case supports up to 175mm air coolers, so it should handle large coolers, such as Noctua NH-D15. It supports 360mm radiators and when using low-profile RAM it can support some thick units. I like the 2.5" SATA support and the nice cover to hide PSU wires on the back. I still use 2.5" SATA SSD to backup data. The PSU compartment has a mesh air intake, an air exhaust and is it isolated from the other components. The Antec Flux M supports long and thick graphic cards and there is a GPU support bracket built-in into the case. Depending on the motherboard PCIe place or thickness of the GPU, you might have to remove the included 120mm fans located at the bottom of the case. There are a few things Antec should revise. The cutout to insert the GPU should be a tad taller. I had to wiggle the GPU rear bracket and it was too close to motherboard capacitors. You definitely do not want to knock out motherboard capacitors when installing a GPU. I think Antec should have supported back-connect motherboards, just in case I decide to upgrade to one of those motherboards in the future. I would have like if all six fans were all one color for better aesthetics. Either pick all black or all ARGB fans. Even just three matching fans would have been better. All six fans' wires came daisy-chained together. I do think is a good idea to runs six fan from a single fan header.

★★★★★Perfection
This case was incredibly easy to build in. It’s very spacious, so you don’t have to worry about parts fitting, and cable management is simple thanks to the rear panel and plenty of tie-down points to keep everything clean. It comes with 6 preinstalled fans (3 RGB), which saved a lot of setup time. I built a mid-range gaming PC with used parts and even a massive PowerColor 6700 XT Red Devil fit without any issues. The built-in GPU support bracket was also a nice bonus for such a heavy card. I had just built a PC in a cheap $40 micro-ATX case before this, and it was a nightmare in comparison. Spend the extra money — it’s worth it.

★★★★★It’s great
This is a great case. I got it because I didn’t want the hassle of buying and installing more fans. This has 6 and they are doing a great job on my gaming rig with an RX9070
