Hey everyone, been lurking here for quite a while but I'm finally making my first post to show you guys a case I've been designing :D

This all started when I noticed how the heat spewing out from my 970 was heating up my hard drives in my Elite 110. It's still within the safe temps for hard drives (about 47 degrees), but it gave me the idea of mounting the drives behind the mobo, isolating them from the heat of the other components. I was also not completely satisfied with the look of the 110, I like the aesthetic of a mostly featureless rectangular monolith, which the 110 isn't. I liked vertical layouts too because of their small footprint. So, I started to play around with those ideas in Solidworks.

I ended up with what is essentially a Silverstone FT03 Mini with my own spin on it.

(I cut down the number of screws in a later design, too many screws make the case look like it has chicken pox)

Some more ideas came up while I doodled in solidworks:

-An open inner frame that would be easy to build in, and then the outer panels would attach to it give it rigidity. This results in a simple overall design with a functional, industrial look (i.e. screws and stuff showing everywhere)

-Water cooling! Looking at liquid cooled builds with single rads gave me the idea. WiSK's in particular, as well as this, this and this. I'm not looking to overclock (hell, I don't even have an unlocked CPU), the main reason is for the looks :cool:. Also, this'll be my first custom loop.

The case will be made entirely out of 3mm aluminum, bent to shape.

The dimensions are:
- Full Outer Dimensions(DxHxW): 202mm x 391mm x 246mm, 19.4L
- Dimensions without the top and bottom voids: 202mm x 295mm x 246mm, 14.6L

Two 3.5" drives are mounted in the back compartment using rubber grommets, up to 3 SSDs stacked up on each other can also be mounted in the same way.The res is also mounted here, which is of course a Swiftech Micro Res. I'm a bit iffy with having 3.5" drive support since SSDs are getting bigger and I can mostly replace them with external drives, but I do find myself using them a lot as part of my workflow and to store games and shit.

I'm planning to use a Fractal Design Kelvin CPU waterblock/pump. The design fits really nicely with the rest of the system, and the little pump is probably enough for this loop since all the tubing runs are so short (there are a lot of bends though, which do add resistance). I was considering the Apogee Drive but it has a troublesome fitting arrangement, while the arrangement on the Kelvin lends itself nicely to rigid tubing.There is enough space for a 140mm thick (60mm) rad with fans in push-pull.

Long graphics cards up to 289mm can be fitted, but I'm probably going to be using my short PCB Zotac GTX 970 for now.

There's enough space for an SFX-L PSU, hopefully Silverstone sorts out the fan issues.

Of course, there are flaws in this case, criticizing my own design is part of the process anyway :eek:. First, the 'void' in the upper part of the case where the cables go is barely enough to clear the height of a DVI cable, and the I/O port is very hard to reach once the top cover is screwed in place. For this I'm relying in the fact that I have small, feminine hands and thin fingers, plus the fact that I rarely need to access that part anyway once everything is plugged in. The second flaw is that maintenance will be a bitch. because of how the outer panels attach to the inner frame, I'll have to take out 13 screws just to take off the front cover to get to the insides. I guess I better get an electric screwdriver..

Here's an exploded view to show how the parts come together

And here's a fun little render with the case invisible :p

I should say that I didn't model most of these parts. I got the models of the GPU, rad and some other stuff from GrabCAD.

Here's a size comparison with the FT03, they're pretty much the same

So, what does the hardforum community think of my humble design? I've also got a few questions:

-Acrylic or PETG? both have their pros and cons, although since I want this rig to be portable (I probably won't be bringing it out very often, but just in case), PETGs impact resistance and flexibility will probably make it slightly better for my uses. Ultimately though, it'll probably depend on whether I can find PETG tubing that can fit on the 12mm bitpsower fittings I plan to use.

-Does anybody have experience using the Fractal Design Kelvin? I've seen glowing reviews for it but I've never really seen many examples of it being used in a custom loop.

-Should I ditch the reset button? It seems as though it isn't used much anymore these days.

-I'll be sleeving my own cables, but I want to do something slightly different for the 24-pin cable. it'll be very short of course, but instead of sleeving the individual wires, I'll have one big sleeve for all of them, so it'll be just like the stock cables except all the wires are black and it's sleeved in a nice grey color. This is because the normal sleeved 24 pin looks like it takes a lot of space, and the flaw in the orientation of the modular cable plug on the silverstone psus will probably make it look messy too. I don't much mind the look of naked wires, or maybe I'm just weird. So, is sleeving available in the larger diameter that I'll need?
 
Looks great and I love the integrated handle into the case. Keep in mind that silverstone owns the patent on cases that have the videocard mounted in the way you do, one of the reasons the Ncase switched away from that design early on. You might be able to skirt around it with the handle being built in.
 
what's patented about the way the card is mounted? I don't get it. Can you get the source/patent info?
 
The patent number is Taiwan Patent M336464.

I know it has come up multiple times before in these forums the gist of it is due to the 90* mounting rather than videocard specific. Why else do you think you don't see any other 90* cases out there, the only other one out there that is even close is the originpc one and I think that one skirts the rules because it is configurable rather than fixed as 90*.
 
Did they get the patent outside taiwan? I've seen the european application but I don't really get it how it's possible to patent something like this.
 
I'm aware of the patent, saw it while going through the Ncase thread. I'm not planning a production run at the moment though, just gonna build this case myself.
 
Sorry for offtopic

@SaperPL: They have a patent for this layout in europe for nearly every european country you can see it in the european patent database.
You can made a patent on everything if the idea is new and nobody has published something like it. This means if somebody offer a idea without having a patent on it,
nobody can made a patent later.
 
I'll chip in here... We have patent for 90 degree rotated layout in Taiwan and China only. The US patent (5243493) for this design was actually filed all the way back in 1992 by the "Industrial Technology Research Institute in Taiwan" so it has already expired.

This means you are free to make any case with the 90 degree rotated motherboard design on your own and would only need to consult with us if you plan on mass producing cases with this design in Taiwan or China.

Let's sticky this post. Thanks Tony!

There'll be no problem with me making this case here in Malaysia then :). I have access to my uni's engineering workshop, where I'm free to do personal projects as long as I provide the raw materials myself which is why I'm using the same material throughout to save costs.

If I did intend have a production run of this case though, it'd probably need a redesign to make it better for the masses. I'd gladly do that if it happens to be popular enough, but right now it's made according to my own preferences as well as what I can tolerate.
 
This is very cool! Not all that small, but very unique and good looking. I love it, go forth! :D
 
I think ive read somewhere that those patents last only 2 years exclusive and than the approach is free for the rest.I think exactly a month ago abee made their version of the silverstone ft03 using the same method and i think others can do it too?Example:
http://www.abee.co.jp/Product/CASE/AS_Enclosure/RS07/index.html

Cool case but terrible airflow,cable managment,size and is a mystery on how do you plug a usb in the motherboard XD.

All grey,awesome case by the way!I hope you consider aircooling as a option.

Thanks for the feedback! Yeah it isn't the smallest sfx case around. I blame the 3.5" drive support, eliminating the back compartment brings the volume down to ~11.6L. But I do need to have them, for now at least.

In Taiwan, it looks like the patent lasts till 2018 (according to this, search for M336464) but admittedly I don't fully understand the whole thing at the moment, definitely have to study up on it though.

I'll definitely consider air cooling, but it needs perforated side panels to make the airflow not suck, unless I can find a way to implement the current air intake method to the other parts of the case. It's watercooling that really makes the clean look possible though.

I'm actually gonna be building another case along with this one out of the leftover aluminum, it's a tiny ~6.5L case that's meant to take advantage of small itx GPUs. It uses the same assembly method (panels come together to give the overall structure rigidity), and only uses two parts if you don't count the handle.

I call it the Greyling :D
 
Looks really good, both designs!

Two recommendations:

Round off any outside 90 degree corners, your hands will thank you during assembly. For example with Greyling the 4 corners on the left side of the case are sharp points.

Go for a loose fit diameter on the mounting holes in the exterior panels. In reality not everything will line up perfectly so having the extra wiggle room will save you lots of headaches.
 
Could you please render in perspective mode instead of isometric? Isometric renderings trigger my puke reflex (not kidding; it actually makes me nauseous). :D

Thanks for the suggestions, I'm a bit of a noob with modding and scratchbuilding so tolerances will probably be a big issue for me.

Here you go ;)

These are just the default settings in PhotoView 360 though. I didn't actually know what perspective mode was until I saw your comment, I have so much to learn
 
Quick update
Ha1AROD.jpg

ditched the reset button and rounded off some corners. Also changed the mesh design on the Greyling.
 
So I recently saw a review of a TFX power supply on Jonnyguru which got me playing around with alternate Greyling designs using this form factor. Thing is, they don't seem to output as much power as conventional power supplies.I'm just wondering, would this be enough to power something like a GTX 960?

k8CxYXN.png
 
There is a PEG8 connector which means it should be able to provide up to 150W through it (by PCI-E/PEG specification) which should be enough to supply up to GTX 970 itself and there's still the power drawn directly through the slot (up to 75W). GTX960 should be okay, 970 or even 980 may be possible.
 
Jup, that's definitely enough. I'm running a 970 off a 300W PSU, no worries there. :D
 
Well, It does state that it may supply a max of 348W on the 12V if needed (though it seems to have 2 rails for it). So it could easily feed a 980, I believe.
 
It's probably a single rail anyway, being a VRM design (and having each individual rail rated for significantly more than 1/2 the total 12V rating). Be a bit weird to try and cram two actual rails into such a small volume, rather than just one supply and two individually fused outputs.

I've actually seen that on many small 1U and FlexATX PSUs, single strong rails seem to be harder to pull off than two weaker rails that have the same output. Not sure whether that has to do with volume or whether it's easier in general.
 
Thanks for all the info guys, although I've decided to stick with the original design just because a standard SFX psu is probably much easier to find than more exotic form factors.

Speaking of the Greyling, I've cleaned up the design a bit

I don't believe I've shown you guys the internal layout yet, but here it is. Its exactly how you'd imagine, given the simplicity of this case

Some big news, I've got my hands on the aluminum that I need for this project, so expect to see some actual work in progress pics soon!
 
Guys, I have an idea for using a standalone DDC pump and cpu block instead of the Fractal Design Kelvin. Using a Bitspower Q plus fitting, a vertical piece of tubing would be attached that'd act as a 'reservoir' of sorts and more importantly a fill port, sort of like using a T-fitting in resevoirless loops. Would something like this work well?

I'm not an expert in watercooling, but shouldn't the pump be at the lowest point of the loop?
 
That'd be ideal, but it should be fine as long as you make it so that it doesn't run dry.
 
Great design on the loop - it should be fairly easy to fill. There are two very big issues, though.

1) That 'reservoir' / fill point absolutely needs to have a cap on it so that dust, ext. doesn't get into your waterloop.

2) With the pump bolted straight to metal like that, its vibrations are going to make noise.

Thanks for the advice, but of course I'm gonna put a cap on there :b
Although, it seems that the only way I could do it is fitting > female to female adapter > cap. There doesn't seem to be a more straightforward method than that for rigid tubing, like a fitting with a female thread.
 
Very cool, very unique. I like the Transformers-esque feel it has (to me anyway). It's probably too rich for my blood though, I've never wanted to invest in water cooling.

I'm jealous though, I've always wanted to design my own case... I would probably do air cooled and set a standard dual slot ITX on its front, put some short feet on it, and do a mesh hood on the top where all the cables plug in to make it look like the cables are still coming out the back...

Interesting that you say it has a transformers feel. Some of the stylings of this case, particularly the panel lines, were inspired by gundams. But you can definitely learn Sketchup and just play around with it and design your own case, 3D modelling is fun :)
 
Small update!

For the Greylith, the previous design had some bends in it that would be impossible unless I had a fancy bending brake, so I made some of the parts of the inner frame separate pieces.

Here you can also see the adjustable radiator mount, to help with alignment for the new tubing arrangement.

I've put a proper fillport on top using a passthrough fitting, adjustable for different radiator in/outlet spacing.

For the Greyling, I decided to elongate it slightly to fit a standard 120mm fan. I've removed the front cover for now, still thinking about a proper front grille design

I'm thinking of adding some USB and audio ports on the front as well.

That's it for today!
 
I really like the all grey colour scheme and the industrial design. All those screws make this look amazing. The blue LEDs inside the buttons are a bit tacky, but I understand that they are popular.

Overall 9/10, hope this gets to be a real case soon.
 
Very impressive, but i'm gonna wait for the smaller version especially for the TFX one!
