Raijintek Thetis Classic Aluminium ATX Cube Case Review

Raijintek Thetis Classic Aluminium ATX Cube Case Review. I’ve been waiting for this product for a long time, and I’m hyped to review it finally. Way back when I reviewed the original Metis, and then its bigger M-ATX brother (STYX) I couldn’t wait to see an ATX version. It’s finally here, in multiple colors and with a very enticing price tag. UK Pricing on the day of review is £86.99  (correct at the time of writing from OverclockersUK) Both the classic and tempered glasses version are priced the same, which is crazy right? Styled upon its predecessors this case offers full ATX motherboard, ATX PSU support and enough space in the roof for a 240mm watercooler. Let us answer the obvious question… is it any good?

[nextpage title=”Packaging and Bundle”]

The first thing that had me thinking was the box size; it’s much smaller than I anticipated. From the exterior you can identify its color and side panel options. Inside Raijintek has done a mighty job of packing the product, to ensure it arrives in pristine condition.

[nextpage title=”Product Tour”]

Normally we would look at the product exterior, and then take a closer look inside. Today we’ll still do that, but because I have the tempered glass version, it proved somewhat difficult to keep the inside a surprise, and a real pain to photograph too. Likes its brothers Raijintek have kept the simple no-nonsense front panel.


With nothing more than a discreet logo on the base and stylish push button at the top.


As I mentioned earlier, it’s way smaller than I expected but as you’ll see that’s a good thing, and there’s been no comprises made. For reference sake I stacked it side by side with the Mini-ITX version AKA the Metis plus.


On the top they’ve taken the same design, they implemented into the STYX Micro-ATX case, which we reviewed in the past. Under that sleek and discreet filter, is room for 2x120mm fans, or a water cooler but more on that soon.



Again, Raijintek has taken a practical design from elsewhere and reused it, but now with ATX support and 7 PCI slots to play with. One of their new fans in preinstalled, sporting an eye-catching white LED. A pleasant and welcome addition to the case.

If you’ve seen the other models, then you’ll know that is a PSU power pass-through port, which runs to the PSU in the front of the case.  While I’d like to have seen a 140mm exhaust here, I’m happy enough with a 120mm option.



Turning the case over to examine the floor, again it’s essentially an enlarged version of the Metis and STYX, like the STYX you can install a 120mm fan on the floor, and also 2x 2.5″ drives. What’s not clear to me, is why one of the drives mount sits over the 120mm blowhole. They had enough room for all 3, but for whatever reason, they’ve gone for this design. As we move on you’ll see it is not a massive issue, but still odd right?


The glass panels, proved impossible to photograph, but I must mention the ease of installation and removal. I’ve reviewed a few cases with tempered glass now, and while I adore what they bring visually, they can be annoying to fit. That said, these are by far the easiest to line up and refit I’ve seen. Their chunky, heavy and excellent quality. I would like, to have seen to additional protection, just in case any scratching occurs during shipping, but our sample arrived with not a single mark on them.



With the glass removed, we get our first glimpse inside and I’m seriously impressed with the layout and design here. For the first time, we see rubber grommets too, something not seen on earlier models.  Don’t worry about the rectangular slit on the left of these, as its completely hidden once you start building.  Inside its basically a direct copy and reuse, but slightly tweaked.

Internal cabling is neatly bundled and locked together for a cleaner finish and to help with the cable runs. Something not likely to see much action is the 3.5″ drive plate, that said it could be removed with a simple thumb screw.


Inside the Metis to aid with cooling, 2x120m fans can be installed and you should make use of that for sure, as this case has no air intake at the front. For radiators theirs no real limit but because the motherboard is inverted, a setup of push-pull fans will impact the lower PCIE slots however eventually. Unless you plan to run a mulit/ tri card setup, then you’ve got no reason to worry!

Looking at the backside of the motherboard tray,  there is a ton of room here for wiring.

Raijintek has made clever use of the motherboard tray with a  further 2x spaces to install drives. They’ve also added various clamping points for routing cables. As this side is also covered with a glass panel, you’ll need to spend some time getting it right. No issues to report with cable hole locations or sizes. A final new design element is the oversized CPU cutout, something that’s been an issue on both the METIS an STYX, but certainly not this time! So there you have it, and the first impressions are….just wow!

[nextpage title=”The Build”] Building in the Thetis should be straight forward and hassle free for most users, that said… I have a few tips that are worth sharing. You must install the rubber grommets into the motherboard tray and secure your SSD and other drives into place, before placing the motherboard. If you have a modular PSU then route the 24 pin  before adding the actual power supply into place.

Likewise, the USB 3.0 header might be troublesome, so fit that first.  Make use of the large rectangle slits to pass PSU wiring into the backside of the case, and not the grommets.  Finally, add you water cooling setup before the motherboard, and then lower it in at an angle.


We added as always,  our monster sized 220mm long Coolermaster PSU, and yes it does fit with ease. Once we switched to a regular ATX sized PSU (left and right images) that really opened up options for longer GPU’s

The case is really interesting and the end results are fantastic. You’ll need to be mindful of cable mess on the left side, a modular PSU or cable extensions is what I would suggest for a cleaner build


Final Thoughts

So then it’s time to wrap up our findings and deliver a verdict. First of all, was it worth the wait? As I said earlier, I’ve been waiting about 2 years to see the ATX version, and in short yes it was.

Is it perfect then? Sadly not, but the issues I have are trivial and not likely to annoy many consumers. Personally, I adore its small footprint; I much prefer this to something oversized. That said, I do wish it had been just a little wider and deeper. There’s just not enough room between the PSU and motherboard for my liking. Everything fits, but I would be happier with just a few millimeters more breathing space. My only real gripe is the 120mm mount in the floor, that is shared with one of the 2.5″ drive mounts. I just don’t understand the logic here; there is enough room in the floor for the fan mount and two areas for drives, why they overlap is just baffling.

Onto the more positive, and I could talk all day about the case. Lets’ keep it short and on point. Visually it is a stunning product and its 99% practical too inside. Now that we have an ITX, MicroATX, and ATX versions, my respect for Raijintek has peaked. Apart from my nitpicking, this is an almost perfect product. We have a choice in size, color, and a windowed or classic version. This is something very few brands offer. The sheer amount of hardware that you can install in this cute size case is mind boggling. Pricing finally, is very impressive when you factor in materials, finish, hardware support, and overall choice that is available.

As in the past, today is another win for Raijintek, and I can’t wait to see what they bring to market next. The product is available now at OverclockersUK
