*edit* I decided just to buy an Aria and mod the heck out of it. Look for updates in the near future! **

I have a Dream!! My dream is to not pay $100 for a poorly designed case! :) Actually, I have been following the Antec Aria following for some time now with great interest. The concept of upgradability and the diminuitive size (comparatively) of the Aria is very appealing. However, some of its "features" are not so appealing. So, for the last couple months or so, I have mulled over some design features for my new case with the Aria as the initial inspiration. Below is a schematic, or my hopeless attempt at one, for what I intend on building. But some information first:


My target motherboard is the Biostar M7NCG 400 which is why it is pictured in the design.
The heatsink dimensions are exact and are taken from the Thermalright SLK800 which I know people have been able to use in the Aria.
The DVD drive was measured from my current DVD burner


The overall case design uses a 120mm fan in the front of the case to blow air into the top region and the bottom region. The two regions are separated by some type of material that will ensure the air between these regions does not mix. Of course, there will be holes in this to allow the IDE (currently) connections and the power connections to pass through.

I intend on using modders mesh or some other material for the back panel so I don't have to use the 80mm exhaust fan I currently have listed. But if it improves airflow, I might keep it.

This next pic shows how two of the supported three hard drives sit as well as the orientation of the fan and power supply.

In both pics, airflow is from the left to the right, with the 120mm fan depicted as the large blue box on the left side of the case.

If you are clever, you will notice there is the possibility of this system having 4 hard drives in the bottom bay. However, since all of my drives are currently still IDE, I can't separate them sideways like that with my current cables.

The power supply I am going to modify is a 300W fortron standard supply. When I bent one of the toroids over, the whole thing (without the case) is only 2.25" tall. Since I also plan on moving the power connector, I didn't need all the extra depth the current case has either, which makes it 4.25" deep and 6" wide. Turns out these power supplies are just wasting space!

Actually, if it wasn't for the fact that I could get the PS this small, I wouldn't even have begun this project.

My design currently has overall dimensions of: 13.13" deep by 8" tall by 9.93" wide. Compare that to the Aria, which has 13.2" deep by 7.9" tall by 10.6" wide and you will see they are quite comparable. However, I feel my design has better thermal properties and I can even add a port tube to the top of the case to route fresh air directly to the cpu heatsink.

So, what do you guys think? I am going to do a 1/4" plywood mock-up first to see how it performs and then think about building a 'real' version.

Since I know this will probably be asked, my current dimensions allow for a 3" tall heatsink before it will run into the cdrom drive. If you can find a shorter optical drive, you can have even more room. The cdrom drive was placed fairly far forward to allow as much heatsink clearance as possible.

You can get some really small heatsinks designed for server racks, such as this:

It looks like the video card will hit the CDROM and HDD does it not? Also it looks like the video card is not going to have very good cooling because usually video card chips are on the down side of the card. From your diagrams the down side of the video card is not going to receive much airflow.

damn. I had a nice reply typed up and I deleted it :( I'll make it more concise this time :)

About the heatsinks. I would recommend you check out the Volcano 10+ that I use in my project HERE (http://www.ocforums.com/showthread.php?t=315717)
For $17 you can't really go wrong.

Dynatron also makes a lot of excellent HSF which you might want to check out.

I'm not sure what kind of overclocking you want to do so if you have the space then by all means go for the SLK 800 :) Just remember that it will be rotated 90 degrees since that's how it mounts. ;)

As for the slimmer CD drives. If all you need is a DVD capable drive then I might have something for you. I don't need two DVD drives in my mini PC ;) PM me if interested.

Yeah, I noticed that last night too. I will probably just make the case taller instead of getting a slim dvd drive.

The only reason I used the slk800 was because it is one of the few high performance cards that don't require the mounting holes. But I checked it this morning and the CNPS7000-CU from Zalman will fit with loads of clearance. I am going to have quite a bit of unused space in this case, but that just means I have more room for other "unplanned" additions right now.

I haven't a clue for what this PC is for (i'm guessing HTPC?) But to solve the gfx card clearance you could try the laptop CD rom as I suggested and if that still doesn't clear try a shorter card like a GF3 and if still not then a half height GFX card and if still not then use on board. But I'm thinking that with the slim CD drive even a full height card should fit :)

BTW what app did you use to make your design?

I used Coreldraw to make this. The reason I want this is because my current computer is too large for my liking anymore, but I want the flexibility to add whatever components I see fit. The Aria was the best thing my research has come across as of yet, but the thermal problems make it unsuitable for my application. Way overclocked XP, o/c 9800pro, 3 hds and one optical drive. The onboard stuff doesn't bother me, but I am constrained by my current hardware. Even though I would LOVE to get a slim cd, I probably won't.

Thanks and keep the inputs coming.

dont know if you have ever seen one of the arias run in real person but they are quite loud , you might want to take into consideration and change out the power supply fans for some quieter ones.

I am planning on using one 120mm enermax fan in the front per the diagram. They push a TON of air! That fan and the gpu fan will be the only ones in the system unless I end up needing that 80mm fan in the back. Today I ordered my motherboard, so I should be able to do some better mockups in the upcoming weeks.

Ok, here are the new drawings based on inputs received so far. I had to raise the cdrom drive so it would clear the video card. The problem is, now this thing is getting pretty huge. The frontal surface is a 9.5" square... not exactly very small. I have a LOT of stuff I can cram in there, and as I mentioned before, I will have the future capability of supporting 5 drives in this system, but that is kinda nuts for a SFF.

While I am off pondering my design, I leave you with the new pics

That 120mm fan will push alot of air but it is not going to do near as much good without a rear exhaust fan. The power supply will draw some air over the hard drives but you will need to have moving air across the processor.

Or atleast some kind of passive exhaust.
I recommend considering a smaller TFX12v power supply (I have a spare if you want it) mounted above the processor, and then move the DVD-ROM further over toward the PCI slot side of the case. This aould allow you to drop the motherboard down to the bottom of the case and possible arrange a better airflow setup. If you want me to I could work up a 3D diagram.

so you think I should put that 80mm fan back in as an exhaust as I originally planned? I just have to think that 120mm fan will do ok as it is moving about 80cfm by itself. The cpu will have a intake duct (not shown) so the only thing I need to do is get rid of some of the air.

Also, I am already working on rev 3 :)

Do you have some info on this power supply like a brand or sizing or something? A 3d diagram would be great!

Well, I decided to take the plunge and just order the Aria... Not that I am going to leave it stock or anything but it was easier just to have the internals already made rather than try to fabricate them myself. I have a GREAT mod project in the works for this so stay tuned in the upcoming weeks to see the progres.
