Computer case design - feedback

Hej everyone!

I'm Ingrid, an exchange student from Spain. That's why I'm not able, yet, to write in Swedish, sorry about that...

I want to show my project, because I would like to know your opinion and the mistakes I made so that I can improve my design to suit all of you.

This computer is based on modularity and accessibility. The users are who choose how to distribute all the components. In this image there are only three boxes, the first one contains the hardrives, the powersupply and the optical drive (as they are the ones which give the most heat off, so we can create natural cooling), the second box contains the motherboard and the last one only fans. The users can add as much boxes as they like, and of course they can use them as storage boxes for the tools, cd's....

All the boxes turn around the main axis, which is the on/off button and also it is where all the cables go through. This part of the computer opens in order to offer a good management of cables. The idea to pass all the cables through the main axis is to avoid tensions while turning the boxes.

Of course, every box has a lit with dust filter, that can be removed easyly to work on the components.

Well, hopefully with my explanations and the pictures you can understand how the computer works and of course, if you don't, don't hesitate to ask.

Tack så mycket!!!!

Sry, but the main heat in a PC is coming from the GPU and CPU (~300W+ in heat in total for a highend system), the HDD themself don't create very much heat nor does the PSU.

EDIT : other than that I like the idea and the design, would look great as a HTPC.

Sounds like a good concept Ingrid but the details are what make a great product imo. You should consider airflow: optical drives, hard drives and the powersupply are big producers of heat sure but the big heat generators in a modern system (especially a high-end one) is the processor and graphics card. How are you planning to get cool air into the motherboard compartment? Some more detailed plans of the box would be great, the pics so far look great though! Keep up the good work.

PS. Don't forget the problem of motherboard backplates and ports. By the look of your ports section one could think your chassi required a custom built motherboard or some sort of extension for all the ports.

We need to see more pictures of the design from another and closer view. Its hard too see how components and chassis will work together to bring the heat out the most effective way possible.
Maybe some schematics or more like "blueprintish" pics would help :3

But what I can understand of the design so far is that the air is coming out from the top. If so, don't put the filter on top. A filter at the output will do nothing but keep the dust in and on top of that hinder the air from escaping easily. Filters should as a rule always be placed by the intake, to prevent dust from entering the system in the first place.

Allso, what's about the big On/Off-button? If it's that big and exposed, well I would be nervous pressing it by accident, or drop anything on it
If you're gonna stick with the big red button, make some sort of housing for it.

It's not that you don't comprehend what's laid out before you, or that you're unable to process. It's all about what you're to live up to, your position, an identity created by the expectations of your affiliation.

Thanks a lot for your comments. I'm sorry I did this mistake, I really thought the power supply was heating a lot... But the idea is that everyone can place it as they like. In this case the motherboard should be in first place and than the other components. But the other components don't have to obligatory in one box, we can sepparate them as we wish.

When I was designing it, I thought I wanted to do natural cooling: the fans on the bottom bringing the heat up. But maybe every box can have independent cooling.
>> Do you think is better to sepparate the components in order to have more space in the box for fans?

>> Or just puting the motherboard on top (with its fan), the other components in another, and a box with fans it's enough?

Actually, as I said, everyone can choose their own placement but I would like to make a standard one which works.

According to the ports:
I don't want to have a custom built motherboard. I want to make use of the ports that are already in the motherboard, I don't want to make an extension, maybe I should draw them more precisely.

Dust filter:
I should have mentioned that I wanted to have the lit for every box with holes (for the outcoming air) that's why I wanted to put dust filter. So what do you think,

>> Should the lit be without holes for airflow in order to prevent the dust coming in?
>> Should the holes better be on the sides of the box?

ON/OFF

I completely agree with you, Alakai, it's very easy to have an accident with such a big button... I'll change that!

So, regarding all your comments, I'll try to change a bit the computer. And I'll come back with more uploads.

Thanks a lot for your help!!!

This is a good piece of work. I have some suggestions for you: always choose big fans, they provide more airflow to a lower sound level. But if you have designed using 120mm fans you may be good because the market space for that models are bigger than for the bigger ones like 140 or 200mm.

You may also consider making the feet a little bit taller because if there is such a small space between the floor and the chassis, the airflow will be limited. And just like the others say, the dust filter will be better suited by the intake.

Have you thought about placing the swivel outside the box?

That would give you two things:
Better room inside the boxes, currently you have room for 3 120 mm fans, removing the swivel would give you room for 4 fans OR one huge 240 mm fan. That would be a really nice option I think.

It would, I think, give the case a more unique look. Currently at a first glance it looks like most cases with its square shape.

Thanks for your inputs. I am working on all your comments.

Linqon, regarding your comment, what I did is to make the swivel much smaller, so there is enough space to put 4 120mm fans and even a huge 240mm fan. Thanks for your advice, because I realized it was maybe too big.
I will post some more pictures tomorrow!!

Thanks a lot for your help!

Hej all again:

According to your comments, I tried to modify my case.

I did a smaller swivel that makes the interior space of the box bigger and allows the user to place a 240mm fan in the bottom, and of course 4 120mm fan, as wished; and also have more space for the other components in general.

I also arranged the ports as they are nowadays because I don-t want to use a costumized motherboard as it seemed in the previous post.

I added a piece at the end which raises the box from the floor and separates it from the dust.

The cable management is the same as it was before: it goes through the axis. The user will be able to choose the lit from transparent or opac colour.

Please, Im open to feedback in design and technical aspects.

Thanks a lot for your time!!

Great design and great idea!

Me and a friend have been discussing the placement of the ports (such as USB, Firewire) but most importantly extension cards need (for a lack of better term) holes for their various connectors on the side of the chassis.

In it's current form it looks like you wouldn't be able to install a seperate graphics card for an example?

Oh! thanks!! Yes, you'r absolutely right. Now I was thinking that I should place all these ports on the bottom part, because otherwise it will be a mess of cables. And I'll put the holes for the cards! : )

Ok, we also thought about just that, a system for routing the ports to the bottom/back would be very nice but then you'd need to route the cables "outside" the chassis since the add in cards ports will be aligned the same way the motherboard ports are.

Another problem is that many videocards use a "PCI-slot" for cooling intake/outtake. Those cards would simply not work without a traditional slot.

We were thinking a modular encasing that you can snap on individually for each port to hide it properly within the design.

If I knew CAD I'd show you how I mean.

Hi, i like the colour.

This is how i want my case to be designed:
1. Esthetics
2. Low noise

C. Sufficient cooling
D. Ease of maintenance

1 & 2 are most important, the rest you won't notice very much unless you're into overclocking.
C & D are not that important. Airflow and low noise are two contradictions that should meet somewhere around "lowest noise possible with sufficient cooling". And you mostly build your system once.

I would like a description of the airflow in this case. The motherboard seems to block this as of now.
I have another question too. Atm. I have my case under the desk and it's really nice to rest my feet there during the winter season since it get's warm. Is this possible with this case or is the top too soft?

Great work!

Edit: Oh, are the dust filters washable?

I think I still would have preferred to have the swivel outside the box, but that's just a matter of my opinion.

The order of the boxes seems to have changed, I think the drives and optical drives should be at the top since its more important that the main board area with CPU and graphics card gets well ventilated. But I guess the idea is to make it possible to change order of the sections?

The bottoms of the boxes, they must be ventilated somehow to allow for the air to pass through. I guess you already have taken this into consideration but it wasnt mentioned and the pictures made it seem like the bottom of each box was solid.

It also lacks some intakes where the air can be sucked in since the bottom box seems to be pretty flat onto the floor. There should also be somewhere for the air to pass out. Or perhaps the lid on top is meant allow for the air?

This idea is really beginning to look nice. Just do some detail-studying on the backplate and consider that there will be expansion cards as well. Also, don't forget ventilation holes within the chassis, between the boxes. Maybe you have thought of this, but the pictures didn't show it so I mentioned it just in case.

Edit:
As standard you don't want cd/dvd on the same side of the chassi as the backplate. Maybe you could rotate on of these "boxes"?

Keep up the good work!

PS.
Just interested in which motherboard and cpu-cooler you use as referense?

Note that the placement of I/O-ports on motherboards do not follow a standard so specific as what you seem to have in mind.

Motherboards include a thin metal I/O-shield, which is then attached to the chassis. This shield have standardized dimensions, however the placement of I/O ports within this area varies greatly between different motherboards. As it stands now, your design seems to limit the user to a specific motherboard, which limits the use and upgradeability of any computer built in your chassis.

Here is an example I/O-shield.

Edit: I found a better image:

This shows, in addition to the removable I/O shield, the other standardized components in this area, namely the expansion slots (although 8 slots are increasingly more common), and the motherboard mounting holes for ATX, µATX and other motherboard form factors.

Also, having these on the front of the case might not be such a good idea when considering that some 8-10 cables are normally attached here during daily use.

Hej again!

Reading all your comments I have to say I am a bit stuck with the airflow of the computer. I modified the legs, so now they're open and the air can flow from the bottom.

Every box has holes in the bottom, but then

>>Does every lid have to have holes also?? Because then comes the extra problem of the dust!! And if I put dust filter, than the air doesn't flow anymore? Am I right? Do you have any suggestions on how to solve this problem??

As you will see, I finaly put the back ports in one side, and there are some accessible ones in the front, so that the annoyable cables stay away.

>> I actually changed the order of the components because I understood it was better this way, so that the motherboard recieves air directly from the bottom fan. Do you think it is good this way now?

Thanks in advanced!!

The air has to pass through all the boxes so both bottom and lid of every box has to have some sort of opening. Assuming ofc that the only intake is the one at the bottom.

An airfilter filters air... In other words air passes thought the filter, otherwise whats the point? Some filters are a bit restrictive to the airflow but it's not enought a reason to not use filters.

EDIT: at the bottom, not in

EDIT no 2: On second thought, maybe the top box doesn't need air from the bottom box. If all the hot components are in the bottom box then maybe the top box could have a solid lid. Ofc then you need vents at the sides instead...

EDIT no 3: And you do have "sidevents", I need to use my glasses...

Your last design is really nice! But shouldn't the motherboard be turned 90 degrees clockwise? To get the cables attached on the rear of the case. Or have I misunderstood something?

I believe that you have to lead the air passing over the components. I have a sketch that might clarify how I think.

The way i found it most attractive was when the motherboard was on top.
So I think of it this way, from bottom up:
1 Small box with "legs" for the airintake.
2 Box for fans blowing upwards. Here the dustfilter should be placed, wont be needed anywhere else.
3 HDD, CD/DVD, PSU section.
4 Motherboard.

Every box needs a perforated bottom for the airflow but no lid since the bottom of the upper box makes a lid for the lower one. The top-box needs a perforated lid for the airflow, somehow.

Also it may be that the motherboard box need extra air-intake from one side to cool all components in this section.

I think that the backplate should be placed att the rear of the chassis and CD/DVD along with extra USB, mic, headphones on the front. Don't forget that the PSU needs to be on the rear of the chassi as the powercord connects to it.

This are my thoughts for the moment. Pretty funny to just say what you want, and someone creates a model for you. Ah, and I'm still interested in knowing what reference motherboard and CPU-cooler you use?

Talk about constructive critisism... jeez.

I think this concept looks really cool, it's an innovative idea that makes the computer easier to "break down", if you will, especially for the average user.
I'd be a bit worried about the proportions because it's going to be pretty big, but I understand that you don't have much choice when it comes to the standards you have to meet, which is understandable because for a project like this you kind of need a set of rules to adhere to.
The way it looks right now, it could work for a full scale ATX motherboard, but is probably more suited for the mATX standard.

All in all; I really like the concept, if you get it to work without getting to bulky, i'd definately consider buying one.

Hej!! Thanks sqrpshr! I tried to make it as small as possible and it's a square of 36x36cm and every box is 12cm high, and the fan+the feet=12cm high. So at the end it's a cube: 36x36x36cm
