Cooler Master MasterFrame 700 Customizable Open-Air Frame ATX Case, Panoramic Tempered Glass, Premium Variable Friction Hinges, Built-In VESA Mount, Test Bench Mode (MCF-MF700-KGNN-S00)

I'm NOT a fan-boy or a paid shill. I'm just a guy that likes to build computers. I was searching for an extremely large case for a water cooling build with a full size E-ATX (12"x13") server motherboard (SSI-EEB) I had already purchased 2 large format cases and returned them both due to poor engineering and design. (TT Tower 500 and a Cougar) After 2 failures in a row, I bought this CoolerMaster 700 HAF with a good bit of anxiety.I'm absolutely amazed.The first thing that stood out was they actually put thought into removing this behemoth from the packaging box. It's big, bulky, and very heavy. You can't simply slice open the top of the box and yank it out of there. It's a beast. CoolerMaster (CM) designed the box with 4 little squeeze tabs at the base. You slice the top tape and then pinch to remove each of the 4 little squeeze tabs around the base of the box. Then you simply slide the box up and away from your new case. Talk about EASY!!The next thing that shocked me was how easy it was to remove both side panels. There is a single thumb screw in the back of the case, at the top. You remove that with your fingers, and then slide the top part back about 1 inch. The side doors pop off with a gentle tug and the entire top comes off if you slide it all the way back and lift up. At that point, the case is wide open for your build. No tools!! The top part is held in with the thumb screw and the doors snap into place with metal clips in the case. The side doors go back on just as easily.As I said earlier, I'm building a massive server board with a bunch of water cooling. I'll have (5) radiators in this thing and it will hold them ALL. It has room for dual 480mm rads on the top and a 360 rad in the front as well as the bottom. It also has clear room for a 240mm in the back and I think I could stuff a couple tall skinny rads here and there. It has room for at least 3 good size pump/res combos or plenty of room if you wanted to separate those parts out and hang your reservoirs up high with pumps spread across the floor. You could get 4 pumps on the floor easily..... and that's just the front side. It has brackets for mounting your pumps and reservoirs too. They remove with a simple twist of the thumb lock. No tools.It's a massive case and built for anything you can throw at it. As such, it comes with a giant rack for your HDD. I'm not using those at all so I don't need this rack. I'm using dual NVME on the MB for my OS, and quad 2.5" SSD for storage. I wanted the HDD space to mount a pump/res combo. It comes completely out with a simple thumb press on a metal tab!! 2 seconds and it's out. No tools! Giant hole for almost any other type of hardware you can imagine. Awesome.CM includes a single 360mm radiator bracket. It's in the bottom of the case but removes with a simple twist of a thumb tab. Again, tool-less removal and installation. I got to looking around inside the case and discovered that if you don't want that 360mm radiator on the floor of the case, you can flip it over and mount it into the top or the left side!! (maybe you want pumps and reservoirs down there?) How cool is that?!?! They made the case with the right slots and tabs so that you could move the 360mm radiator bracket into any of 3 different positions inside the case.It does come with 5 fans. There are (3) 120mm fans (back and rad bracket) and (2) of their 200mm fans in the front. It does come with 2 different RGB/PWM control boards. I'm not sure how that will work with my SSI-EEB server MB since I don't have RGB headers. I do want to try and work with it, but I'm prepared to rip it all out and replace with a Razer system. I'll have to wait and see what happens when I get that far into the build. It DOES have the stuff in there if your MB is compatible.It also comes with a plastic case for the included hardware, and there's a LOT of it.I'm just super impressed. It's clear to me that CoolerMaster actually put thought into the design. It's all modular. It all makes sense. Stuff lines up and is put together in a logical manner. 5 stars across the board. Way to go CoolerMaster!!!

This case is absolutely massive in the best way. The HAF 700 EVO gives you so much space for airflow, cable management, and future expansion. I'm still in awe of how solid and premium it feels. Cooler Master really nailed the design and cooling options — and the ARGB setup looks stunning. It’s a serious chassis for serious builds.

Wow!! One of the best cases I've had in awhile. Fits a 4090 with no problem. It is light weight. My son has the black version, but I've always used white builds, so that is why I went with this one. The side panel has one finger screw on the back and then it just pops out from the top, so easy to get into it. I used the Cooler Master 360 Core II White AIO CPU Liquid Cooler with it and it all works great together. Case temps are staying very low, so it seems to have very good airflow. Overall a great case for a mid tower.

PROS:- Radiators breathe freely: though the "grate/grill pattern" is, uh, not very efficient technically. It should have just been a square hole cut out IMO. Regardless, This is why *I* bought this case personally. There is no hot air coming into or out of a closed air case through radiators. I like this a lot. I don't care that it's a very minimal impact. It just feels better to me. Though that means there is no airflow over the Motherboard components like VRM, Chipsets, or SSD... but that's not a problem for me so far.- It is very unique and has a commanding presence. With water-cooling it looks like a mad science experiment.- Very easy to work on. Everything is right there. You can see in the photo I'm fixing a water pump, and it's much easier than a closed case because any water that drips... well just hits the table.CONS:- It's HEAVY with watercooling. Watercooling often adds a lot of weight, but this bad boy is STEEL andLARGE. I HATE moving this thing with a passion, because it's cumbersome, heavy, and the only way to hold it is thin steel sections which hurt your fingers. DO NOT GET THIS if you need to move this PC frequently. DON'T DO IT.- It's open air... so expect DUST. If you put it in "bench" mode, there is slightly less dust coming down on it if you put the glass over it.... but it will still be there from air flow. I didn't clean out the dust to give you an idea of what 6 months may look like.- Takes up A LOT of space. This thing will require an entire side of your desk. Sure you could maybe wall mount it... but it's HEAVY and at that point.- NO vertical GPU mount. Really? For $200 I couldn't just get a little piece of stamped steel that lets me mount the GPU vertically like all the cool kids?- Terrible access to motherboard IO. Especially for video cards if the sides are angled in. Just look at the photo of that GPU. Yeah, gross.NEUTRAL:- Cable management is simply up to your ability. I personally don't care as long as it's not in the way. I want performance and ease of repair/access to components.First off, this is not obviously not your traditional "case". In fact it's not really a "case" because it's hardly more than some nicely put together stamped/CNC cut painted STEEL with hinges and a glass panel. It's hard to put it up against any other of your typical cases in any way. That being said, it's wildly silly and impractical for most users. Please look up Gamer's Nexus review on youtube. It's just not really a product for MOST people...But I'm not most people. You may like this if you're looking for similar reasons I wanted it. I had a bunch of water cooling equipment, I've always wanted to try an open-air solution, and I only care about performance and ease-of-use.1 Year of use:After about a year, I would say I don't regret buying it. Dust isn't much worse than a case without a good filter. In fact, you can just so easily dust this guy out while it just sits on your desk, because, well, it's open to you. But like I said, moving this sucks so much. I hate moving it to another room for various reasons... but you may rarely need to move a computer anyway, so not a big deal.IO sucks. I use usb extension or hubs, but when I have to go back there, yeah, it's garbage. The USB cables often just hang over the top of the case unless they are super long, since going around the thing is like walking around a mountain. If the PC is on your right, it's less awful, but if you put it on the left of your desk, yeah, gross. And the top IO panel is just that. A TOP panel. So the cables just jut out from the top. But I don't' care about aesthetics that much.The hinges have only slightly loosened up since I first tightened them. I don't know how long they'd hold up if it was in bench mode and they were angled up... but they seem pretty strong.
