Small poll:

A GPU is not the only thing one might want to put into the GPU compartment, and I've recently made a change to allow for a fan swap. What would you put there?

Information:

After successfully finishing the Freilite Alpha in the PC-Q12, I of course had to notice how much space was wasted in that case because it wasn't designed for the components I built into it.

So I got to the drawing board and managed to scrape off two more litres, arriving at currently just under 5L. This is the PC that I wanted to build when I built Alpha, and it is now time to make it happen! (Well sort of, I have to finish the design up, but I want to get it out there.)

I proudly present:

The Freilite Brevis S



Isn't she a beauty? tongue.gif

It's this small:

Height: 420mm
Width: 60mm
Depth: 197mm

Enclosing Volume: 4.96L

It will fit this stuff:

Apart from the second HDD and DIMM, the riser and the upgraded PSU, I have all of those already.

Motherboard: Gigabyte B85N Phoenix

Graphics card: GALAX GTX 970 OC

GPU Riser: Custom flexible B-Type riser from LiHeat

CPU: Intel Core i7-4770T

CPU-Cooler: Noctua NH-L9i

RAM: G.Skill Value 8GBx1 1600 CL9, maybe a second one

SSD: Samsung Evo 840 120GB mSATA


HDD: Samsung Spinpoint M9T 2TB, maybe even a second one

PSU: FSP300-60LG at first, hopefully the FSP500-50FSPT




It has these design ideas: (Improvments over Freilite Alpha)

Intakes on only one side: This allows the case to be placed under my monitor, be VESA mountable or even be placed in a HiFi-Rack without suffocating the components and allows an extremely clean look from one side. (Alpha runs without sidepanels currently, so that's a huge plus)

Recessed GPU: By recessing the GPU into the case, the PCIe brackets don't stick out the back and the cabling for its power connectors can run directly into the PSU cabling area. (The former is very important, I frequently stabbed myself with the sharp corners of the GPU mount on Alpha, especially when carrying it around)

Portability: By being very thin and short, this case fits into many sidebags or backpacks while still leaving space for other gear. (Alpha is quite thick at ~88mm which made it hard to put a keyboard alongside it into my bag. It was possible, but not really a pleasant experience)

HDDs far from heat sources: By being placed on the cold side of the PSU and far away from the underside of the GPU, the HDDs experience the most minor heat from other components possible in such a small enclosure. (That's not an issue in Alpha, fortuntely)

Minimal waste of space: By using an angled flexible riser, having the PEG connectors intrude into the area in front of the PSU, letting the HDDs connectors intrude into the Mainboards PCIe connector space and using the space next to the GPU for a front USB3.0 cable, the height of the case is kept at a minimum while using every little bit of space available. (2L less with the same hardware, I'll take it)

Easy installation: To ease installation, most panels can be removed, giving easy access to most components. (Installation in the Alpha is very challenging and must be done in the right order)




What's left to do before I can make it:

Tasks:
  • Thermal dividers between all three main components, maybe made out of acrylic Done
  • Stands for vertical and horizontal mode
  • Sample of the flex riser from LiHeat to make sure it fits Done
  • Redo intake and exhaust holes Maybe done, maybe I'll redo them again

Questions:
  • Should the case be made a little bit taller to make sure the HDDs fit with mainboards that have their socket right next to the PCIe connector and wider GPUs? Currently you can only have two of the three at the same time or resort to one HDD instead of two.
    Yes, added 6mm to allow two HDDs always.
  • How can I mount the HDDs? Adhesive tape seems like the easiest way, it decouples the drives and makes installation quite easy. But it seems like a cheap solution.
    HDD bracket is designed with no drawbacks from adhesive tape.
  • Is there space for a TRRS 3.5mm audio jack? (That's what smartphones use.) I personally like that as a solution for Front Audio because you only have one jack which looks sleek but still maintain all functionality you'd get from two jacks.
    Yes, there is. Now to designing a PCB for that.

  • Is it possible to design the PSU mount in such a way that replacement PSUs can be mounted upside down? They should always have the hot side facing away from the HDDs and I'd want to enable the use of other PSUs. Jup, done.

Very svelte supermodel chassis.

You make adhesive tape sound cheap. Suggest you employ the two-sided foam picture hanging tape. It's strong, offers a little more isolation and not as cheap as tape. Or if you wanted to push the technical boundaries - Velcro. But since you have the height, you could have an elaborate elastic suspension system to reduce drive noise to minimal levels.

But, why use spinners in a supermodel chassis? Don't be cheap! Use a couple 1TB SSDs. If you need to take more data with you, stuff the NAS in the other bag. biggrin.gif

Have fun with the build!

Haha yeah, I remember you saying that biggrin.gif

Yeah that's what I used in Freilite Alpha as well and it worked pretty darn well. Well I would love to have something with strong rubberbands, but there' snot enough space to actually make mounts for that.

Because I'm not a supermodel nor the boyfriend of one so I don't have the money tongue.gif

Thanks, I really will.

Insane idea, hope this turns out great. How will you produce the case? What will happen to your Q12 PC?

Yeah I hope so smile.gif

I've got a few local shops in mind. It's only made of five aluminium sheets, three of which are 2mm thick, two are 1mm thick, nothing too complicated. The most complicated part may be the bend with high radius at the top, but we'll see.
I'll ask a few shops for quotes next week.

No idea about the Q12, honestly. Maybe I'll refit it at some point, but I don't really wanna throw it away.

Haha, hell no, before you throw it away, sell it to me!

4,73 liters, I think that's less than a PS4 / Xbox One. Looking forwards to build updates.

This is extremely interesting , Subbed of course ..
I like the idea of the audio jack in front-perhaps above the usb port?And just for the record , double sided tape has never let me down thumb.gif

In the upright position the only problem I am seeing here is the centre on gravity is too high. You'll need to either put the PSU at the bottom and or a set of feet that extend about half inch on both sides.

It's not well-made enough that I wanted to sell it to you. One of the threads I cut into the motherboard mount wore out and the standoff inside is completely lose. Apart from that, I cannot sell on OCN without being an artisan. So please, no further discussion of that in the thread.

Not quite, but it's similar. The PS4 is apparently 4.4L, the Xbox One is actually 7.2L, and it doesn't even have an internal PSU. I'm sorry, Microsoft, the Freilite Alpha was smaller than that. The Sony engineers seem to know their stuff.

But the Xbox 360 Slim is 5.3L, so I'm smaller than that, which is quite nice. No matter what changes I do to the case, I'll stay below 5L, that's for sure.

Thanks, I'll do my best not to disappoint you. wink.gif Yeah that was the idea with the front audio, I hope there's enough space there. I never said it would let me down, it just seems kind of cheapish.

Designing a stand is already on my todo-list, if you haven't noticed. So far I just haven't had an idea that fit well with the overall design.

The layout looks nice. Looks like it will fit in a standard 1U rack. My Slim Machine build is aimed to be more like the PS4 in shape, it has a more square profile.

Also, having a small access "door" on the side which you can unscrew to install or replace hard drives would be nice from a user friendliness point of view, in the similar way that modern game consoles do. This might be more difficult to do with the way you have your hard drives arranged. But I want to do something like this in my case. Instead of fiddling with cables, the hard drives attach directly to SATA adapters that are fixed inside the case.

I suggest making a angled stand with a bit of style. There is a SFF build about 3-4L in size that I saw on ExtremeSystems but I can't remember the name. It had a stand that was angled diagonally when you looked at it from the front, which added some asymmetry to the design.
