ASUS A31 Black ATX Mid-Tower Gaming Case, Dual Tempered Glass, Frameless

I always build Micro-ATX because I don’t need a larger form factor, and have gotten used to small, cramped cases. This case has plenty of room for everything, and plenty of spots to hide cables. It comes with magnetic top and bottom filters, and the front of the case is also fully magnetic, allowing for easy removal for cleaning, and fan installation. Compared to my other cases I’ve built, this one was the easiest.

If you just need a case for an matx motherboard, then this one is really nice with a lot of space. I know people will say the sama 01 or the lian li a3, but if you just bought an matx motherboard for the cheaper price and you don't mind a case the size of an atx case for a cheap price then this case is for you. Just gets really dusty on the outside if you live in a very dusty area.

This case is very solid and I just love the style, plenty of room also. Overall a nice case.

TLDR: THIS CASE FITS ONE OF THE LARGEST AND LONGEST GPUS AROUND THE MARKET (XFX 7900XT BLACK EDITION WITH Z SUPPORT BRACKET). IT ALSO IS ONE OF THE MOST HIGHLY VENTILATED CASES I'VE SEEN. I rarely write reviews, but this deserve one of those moments. I really like this case. It's not expensive for what you're getting and the 360 AIO Liquid Cooler front and top mount is really rare in a mATX case specifically. This also fits GPUs around 380mms of length. My GPU, XFX 7900XT, fits in this case with a bit of length to go, although, I had to top mount my AIO, Arctic Liquid Freezer 3 360, which is still impressive as I had ease installing my parts in this case. Additionally, this case has 5 PCI cover slots that are REUSABLE. Many cases in this price point are only removable but not reusable; this is such a nice inclusion to this case. Also, it came with all the screws and even zip ties to complete my re-casing of my PC. Build quality is better than anything I have seen at this price point. No sharp edges, a lot of spaces to hide and route cables. PSU and Motherboard power cable shroud is present. Front panel is easily removable for cleaning and actually building a computer. This case also comes with two EXTREMELY LARGE FILTERS: it spans almost the whole top and bottom of the case which are also highly perforated for cooling. DOWNSIDE: It DOES NOT COME WITH ANY FANS. This is a budget price point. Many people who are looking to use this case are in a tight budget. It would have been nice to at least include one or two fans with this case. Overalll, this is one of the biggest compatibility mATX case there is. It has class leading GPU support and ventilation. 360 AIO Liquid Cooler support in front AND top is hard to find in ANY mATX case specifically.

Was skeptical of the low price but the ASUS name was the key plus the board and few other components installed are ASUS that went into this case. Quality for the price is great! Single power/reset block to MB takes the guesswork out of the individual tiny connectors. Lots of room and space especially for air movement and cooling. Slight angle on lower fans looks great and easy to build in!
