Cooler Master HAF 912 Advanced Computer Case 'ATX, microATX, USB 3.0, Mesh Side Panel' RC-912A-KKN1

I highly recommend this case to anyone with a mid or high-end set of PC components in need of a case with adequate airflow and room for expansion. This case is astoundingly quiet and very roomy. 2 x 230mm intake at the side and front near the bottom mean intuitive air flow (i.e. ambient intake at bottom, exhausts at roof and rear where the hot air of components rises to) along with 1 rear exhaust 140/180mm fan (it's one of those) and 1 top exhaust. I installed an extra roof exhaust fan, the Cooler Master MegaFlow 200 with LED for its impressive cooling and sound properties. All in all, the setup work very well. On top of the HAF X, my upgrade also encompassed buying a new CPU and motherboard and RAM. The CPU is an i7-4770k with a Corsair H100i water-cooling kit and the temperatures are the lowest I've ever seen on a CPU (pretty much ambient temperatures across all cores) when not under intensive load. This is surely a testament not only to the CPU cooler but also the case itself. The H100i radiator block fits very nicely in the case on the roof and the dual 200mm exhausts help it do its job very well.Installation-wise, this case made things very easy. It is very roomy and even includes features I was not aware of prior to recieving the case, like the graphic card cooling duct which allows a single 140mm fan to be installed in a graphics card cooling role, taking in air from the front 230mm fan. On the topic of the front 230mm fan, it is a very nicely placed fan in that it cool any drives you might install in the ironically named 'hotswap' (because drives there basically won't even begin to get hot) bays down below, keeping drives at a very desirable temperature.Cable management is made easy in this case thanks to various features like gaps in the motherboard tray made specifically for the purpose of feeding cables through. These helped a lot during installation. The front panel is a nice design also, with a cover for the on/off, reset, and fan LED buttons which comes in handy. The plethora of available ports on the front end is also convenient.All in all I highly recommend this case and wouldn't want any other. For a decent PC you want a decent case, and this looks the part as well as doing great justice to the components it houses with its unrivalled cooling performance.

This is a beautiful case. Some say its ugly but I love everything about it. Huge amount of room for expansion and the sheer size of it makes cooling child's play. The front exterior has many corners and grooves which are easily cleaned using a dedicated anti-static duster, I will occasionally go over it with a half and half mixture of Isopropyl alcohol and water applied with a ball of cotton. Care should be taken when going over the side panel as the rivets holding it in place are plastic, not metal. One of these rivets was missing on arrival but that wasn't even noticed till long after the build so its not an issue for me but others may want to check closer if it might be.As with all computer builds, one should always take ones time less one makes an error and has to undo a step in the build process. In this build, I started with fan placement to lessen the possibility of unnecessary contact with the motherboard and/or other components. The side panel fan has been replaced with a Noctua 200mm and another top fan added, other than that and with all the fans hooked up to a controller, the case cooling was complete. Other cooling options are available and the included manual runs through them, after a fashion but I think four 200mm fans and a 140mm rear fan is quite enough, for me.I’m running an older AMD FX8350 under a Noctua NH-D15 with two NF-A15s without LNAs and temperatures don't go above 50c under load. Cable management is easy and there are other cases that allow for better routing choices but I’m happy with what the HAF X allows. The on/off button seems to present some with a difficulty in that it is next to the smaller front light and reset buttons. The light button is above the reset switch but for added error elimination I would simply suggest leaving the light on.Very little noise comes from this case which was a surprise to me since I have it positively pressured in that all the intake fans run at full tilt whilst the top and rear exhaust fans run at minimum. Its more like a light rush of wind which gets hardly noticed once engaged in a task. I removed the filters for even better airflow and you really do get better airflow without them and any dust build-up as a result is easily removed with the anti-static brush I mentioned before. With a case like this which side panel is so quick to remove and reattach, the entire dust removal process takes minutes though I suspect that, for some enthusiasts, the desire to change or alter something within might be a temptation as it is for me.I’m content that the HAF X has done me proud and that it has dealt with the high temperatures that the 8350 generates, going forward to Ryzen with their much lower wattages will mean lower fan speeds and even less sound from the rig. I’ve seen a lot of the newer cases on offer since buying the HAF X but they don't interest me, not yet at least and I will use this case well into the future unless graphics card get so long that I will have little choice but that's a long way off, I think.I've now installed a Ryzen 5 2600X in this case and couldn't be happier, both with the processor and the HAF X's ability through the motherboards AI to handle the temperatures even better, obviously because the Ryzen runs very much cooler than the aforementioned 8350. With the CPU fans normally running at less than 200 rpm most of the time, I cant hear a thing from the case which is good news as I listen to a lot of music via a rather nice external sound card from Sound-blaster but that's another review. With the new chip and a graphics card I've promised myself this Christmas (another review) I'll be using this case till 2023 at least despite Mr Gates's efforts to frustrate me (another review). Gamers know what I mean.Love the HAF X even more now that Ryzen means that I don't have one eye on the electricity whilst Chopin calms me to jelly as I'm hypnotized by the pulsing lights emitted by my lovely HAF. Write again in 2023.

I have just thrown this purchase into the council recycling skip. It was an Amazon warehouse buy. The 30 return window is gone. It is unsellable on ebay.Never again will I waste my money on Amazon Warehouse. From delivery, the case's plastic side panel was falling off. I spent £10 on black oxide 3.5 bolts and nuts to repair the side panel. OK. Next, I intended to upgrade the cooling. I bought same brand Coolermaster specified size fan to add to the top of the case. It would not fit. It was the right size in theory but you have to saw off the edges, drill holes etc etc. etc. So I went for a "rescued" fan from ebay. This did fit- just, but how geriatric was the "rescue" - my guess is 10+ years - and what if I had to replace the other fans? Then I discovered only 1 of the 5 case fans could be replaced. They just dont make these sizes any more. (I recently discovered that Lian Li have started designing "unique size fan" cases. I will NOT be buying one of those.) So, thinking this was a gaming build, I decided( Screw The Fans!) to do water cooling. Coolermaster says this case is designed for that, right? Wrong! No fitting holes for radiator AND you have to cut out structural portions of the top to get any aio to fit. The case turned into a money pit.
