Streacom reveals DB4 passive cube case

Streacom reveals DB4 passive cube case

Streacom's DB4, pictured by FanlessTech, will offer completely passive cooling for up to four 65W TDP components in a 250mm cube.

Details of Streacom's upcoming DB4 fan-free case, due to launch later this year, have been revealed - and show a clever modular design that could allow for totally passive cooling of a surprisingly powerful system.

According to details provided by Streacom to silent cooling specialist site FanlessTech, the DB4 is a sleek 250mm aluminium cube raised from a surface by a single curved-aluminium 'foot' and fitted with a glossy piano-black plastic lid. The aluminium sides are cut with ridges running vertically, and they're not just for show: each side of the case acts as a passive heatsink for the components inside.

Streacom claims that the DB4 is capable of cooling 65W TDP components on each side, with a separate component able to be connected to all four sides. Speaking to FanlessTech, Streacom's Oliver Pusse explained: 'You can use one side for the CPU, one for a dedicated GPU, and another one for our fanless 250 Watt ZeroFlex power supply.' Even that configuration would leave one side free to cool something else, thanks to an interesting layout that leaves the motherboard sitting vertically and the input/ouput panel facing downwards - hence the raised foot and gap for cable management visible in some of the photos.

It's a clever design, and one that will appeal to those who need truly silent computing, but it is also somewhat limited: while the case is technically suited to up to 260W of passive heat dissipation, its limit of 65W per component - unless the user fancies daisy-chaining two sides together to cool one part, which is unlikely to work terribly well - means that top-end parts aren't going to be compatible. While CPUs will be relatively well supported - Intel's Haswell Core i7-4770S features a 65W TDP, for example - GPUs are going to be a different matter, with only lower-end boards like the AMD Radeon HD 7750 and Nvidia GeForce GTX 650 squeaking in under the 65W limit.

With that said, even with a sub-65W processor and graphics card a DB4 system should offer pretty acceptable performance, and while it isn't going to playing games across three monitors at ultra-high settings any time soon that's a trade-off many may be willing to make in exchange for a completely silent system.

The Streacom DB4 is expected to launch in late September or early October, at a price of €200 (around £170 excluding taxes.)

That wouldn't look out of place as the centrepiece in a dining room.
Give it some subtle rotating mood lighting and it's set!

but who plays games on 65watt parts. It's pointless...

As beautiful as it looks, and as much as I like the sound of a completely quiet PC, £200 is a lot to pay for a case.

There's a couple of problems that I foresee:

While this would be a perfect, slightly different looking HTPC, there's nowhere to put an optical drive (unless you have one as an external USB device).
Also, I'm guessing that this would need a fair amount of space around all four sides to allow for a decent amount of airflow for cooling - so it's not something you'd want sitting on your desk.

Great design, limited use ;)

Also, didn't Zalman or someone else already do a case where one of the sides was just a large heatsink?

looks cool and quiet

Hmm. SLI two 650s to compensate for a possible lack of GPU power? Then again, I'm assuming the case isn't M-ITX only.

Zalman and others did it. I especially remember the Thermalright HSC case

Ugly as hell! Yucky.

Who has four 65w tdp components in a system?

The main culprits are cpu and gpu.

Theoretically you could get away with one side cooling the cpu, which leaves room for 195w cooling power with the three other sides combined?

Love it! Not planning a new build anytime soon, but something to keep my eye on.

I don't know about you, (or anyone else) but I only ever use the optical drives to install new software, and even then, half of software is downloaded now anyway - having a USB one wouldn't really be a massive problem. My machine has had a blu-ray player in it for three years, never had a single blu-ray disc in it, not once, (contender for the stupidest £50-odd I've ever spent...).

Exactly what I was thinking - 7750's or 650's are fairly decent cards for gaming on a single 1080p screen anyway, a pair of them should satisfy most people, (Titan wielders excepted).

TBH, it literally be for super quiet htpc only surely? Seeing as you can buy those phantom evga cards... you are more likely to see a closed loop cooled pc with one of those no?

The 250W passive PSU comes embedded with the case, from I've read here and there. The 200€ price seams more "reasonable" to me.

You could plausibly cool a half decent gaming system in here, but you'd have to be a bit clever in doing it. I'd suspect that this would be best suited to an HTPC, or possibly a nice quiet fileserver/general server.

So how do you cool all the graphics card? Are they going to make full cover blocks for one case?

Oh, God! Let that be a single aluminum tube extrusion. Imagine bumming a slightly taller version from them... The things you could build.

I just fell in love with that sidepanel! :o

wow slap a 65w apu in there and poof decent media pc capable of light gaming that looks good and has no need for fans :o.

well for now it'll be richland, but kaveris around the corner so it's close enough to plan for.
