Cooler Master's new PC case with 5.25-inch drive bay launches in Japan as optical drive boom hits due to Windows 10 upgrade cycle — MasterBox CM695 addresses the country's reluctance to ditch physical media
As evidenced by a recent unexpected surge of sales of optical drives as the Windows 10 upgrade cycle unfolds, Japan still uses physical media, perhaps more than any other region in the world. Due to the country's strong roots in technology and entertainment, mixed with culture, it's the only place that still prefers a disc over downloading or streaming content. Owing to that legacy, a new PC case launched in Japan by Cooler Master honors this tradition, allowing users to fit a disc drive in the MasterBox CM695, which features a 5.25-inch open bay in the front.
Usually, in modern cases this space is reserved for AIO radiators or just used for aesthetics, but the CM695's drive bay can prove to be much more functional — especially at a time when the country is migrating from Windows 10 to 11 and experiencing a dramatic surge in demand for disc drives. Not only that, but the CM695 can also hold up to four 3.5-inch hard drives for the ultimate off-the-grid media experience, or kickstart your NAS aspirations.
The rest of the chassis complements these drive bays with a vintage design that calls back to classic PC cases of the past, while still sporting a mesh grill up front, behind which lie 2x 120mm fans for optimal airflow. It's a large mid-tower enclosure, measuring about 209 mm (W) × 466 mm (D) × 478.5 mm (H), which supports GPUs up to 398mm long — plenty to house even the most gigantic cards of today.
There are actually two variants of the CM695: one with a restricted side panel authentic to vintage towers, and one with a transparent glass side panel for a more modern look. Otherwise, they both still feature solid I/O at the top with a USB 3.2 Gen 2x2 Type-C port at the top, allowing for up to 20Gbps transfer rates. Combined with the disc drive, you'll be able to rip discs and copy over the files to a flash drive pretty fast, or vice-versa.
It's also important to note that, unlike the recently unveiled Fujitsu Ryzen laptops that come with an optical disc drive built in, you have to supply your own for this case; it just comes with a slot for one. This might make the package seem less desirable since an external disc drive can serve the same purpose, but it's still an option for those who prefer to keep their setup consolidated.
Translating from Japanese, TSUKUMO eX., a popular computer store in Tokyo, spoke to local outlet IT Media about how they expect the case to sell in the region:
“It probably won’t be a massive hit, but there’s definitely a strong following among people who still want to build PCs the old-fashioned way. With the ongoing shift from Windows 10 to 11, those needs are growing. Being able to choose something that says ‘you don’t have to give up’ — that’s a good thing.”

The MasterBox 695 costs 24,000 yen, which comes out to roughly $157, so it's definitely not cheap, but it represents more than just surface-level value. A chance to carry forward your physical collection means more there than in the West, and, as IT Media describes it in their coverage, "If it's junk, BD drive is also," alluding to how a case like this transcends conventional budget-conscious outlooks. If you want a Blu-Ray drive in your PC, you now have an option to do so in a modern chassis.

Notton That partial fan cutout makes it looks like a hack job.Reply
That CD drive spot will get in the way of a tower CPU cooler, especially dual towers. There were a whole bunch of creative design workarounds in the 2010's to fix that specific issue.
I know CLC are more popular than in the 2010's, but a 240mm is baseline for 2025. That 5.25 slot is getting in the way of a 280mm or 360mm. -
Misgar ReplyNotton said:That CD drive spot will get in the way of a tower CPU cooler, especially dual towers.
Yes, they do seem to have restricted the depth of the case too much for large coolers.
I have an old Aluminium Cooler Master ATSC case, with enough depth for a full height (2 x 5.25") LTO SAS tape drive, plus two optical drives. It also holds four 3.5" hard disks and two 3.5" floppy disk drive bays (but I don't have a floppy drive installed).
As with any build, you should pick your components to suit the case. If the parts don't fit, you've bought the wrong case. -
mikethepoor It's nice to have that option even in a modern case, but I'll stick with my Rosewill Blackhawk. It has room for three intake fans or a 360mm radiator and still gives me one ODD slot (or four ODDs if I'm willing to drop to two fans or a 240mm radiator).Reply -
dimar I don't see what's the deal. There's no shortage of stock for cases with 5.25" drive bays. I have a 5.25" AFT mult card reader with 4x USB 3.0 ports, and a Pioneer BD burner drive for burning M-Disc for long term storage. If you need one you can easily get it.Reply -
Dr3ams I only buy cases with optical drive bays. I like to watch my collection of Blu-Rays on my PC, plus I rip physical copies of music and still have a collection of software on CDs. The bequiet! Dark Base 900 I own has a drive bay near the top. It can be removed to install a third 140 mm fan, but the case has six bequiet! fans that are more than adequate.Reply -

thestryker I'm moderately surprised this doesn't seem to be using ancient tooling like the last couple Cooler Master released. This looks to be based on either the MasterBox 500 or 600. The official specs show 360mm radiator support on the top so I'm guessing that's why the bay sits as low as it does.Reply
I gave up on 5.25" drive bays because the number of modern case tooling with them can be counted on one hand. There have been plenty of cases with support, but most are using very old internal designs. Either a USB enclosure or external drive work perfectly fine. I went with a slim external drive and the only problem I had was the amount of vibration which was easily resolved with an anti vibration pad stuck to the bottom. -
BillyBuerger I haven't given up on optical discs yet and still buy movies on blu-ray when possible. But that's getting hard these days. I gave up on 5.25" drives in my PC years ago. I have a slim external blu-ray drive. When something comes up that I need it, I plug it in, use it and then put it back in the drawer. My PC is becoming very minimal which I like. In addition to having to have space for a large ODD, that also means dealing with SATA data and power cables and routing those which I don't miss at all.Reply -
bit_user Anyone looking for an decent, inexpensive ATX mid-tower with 5.25" bays could do worse than Fractal Design Focus G. I just built a system in one. It's decent for the price, but beware that in spite of not being exactly small, everything fits rather snugly, inside.Reply

My three requirements were: 5.25" bays, dust filters on all the intakes, and otherwise compact. A big plus was that I could mount dual 140 mm fans in the front. And if you don't like windows, I can confirm that the side panels are swappable (i.e. so you can move the window panel to the other side), but Fractal Design won't sell you an extra windowless panel. Max cooler height (165 mm) might be an issue for use with higher-power CPUs. -

It appears you meant ATCS.Misgar said:I have an old Aluminium Cooler Master ATSC case,
BTW, I never knew Cooler Master made aluminum cases, but I'm also not surprised. So, why did they fall out of fashion? Scratch too easily, or something?
Huh? I pick my components first, then find a case to fit. I couldn't imagine doing it the other way around, unless it's some case you absolutely love and are dedicated to using.Misgar said:As with any build, you should pick your components to suit the case. If the parts don't fit, you've bought the wrong case.
There was only ever one example of that, in my case: the Silverstone PT13. It's as "mini" as a DIY mini-PC can possibly be, while still using standard components. It was quite an adventure that I wouldn't want to repeat, but ultimately worked out pretty much how I'd hoped.
