Any Dual Chamber mATX cases (like BH4) with filtered positive pressure?

[PeterScott]

I saw the Bullet BH4 by caselabs and fell in love with the layout, but not the price, does anyone build something like this, but with more reasonable price and decent positive pressure setup.

All the others I have seen mess with the air flow, or build excessively large, or just look plain ugly: Corair Air 240 comes to mind.

Here is the Bullet BH4, quite small for mATX (W-11.00" x H-9.50" x D-13.0"), yet with a very straight forward ventilation with dual 120mm intakes:

Vertical Orientation.

Affordable Alternatives with this layout? Preferably filtered intakes to aid in setting up positive pressure.

Raijintek Aeneas. Dual chamber layout with horizontal MB. Takes a little modding to optimize intake/exhaust airflow, but decent when tweaked. Stock fans are crap, but can make good shroud donors. After mods my Aeneas has a 2 degree gradient between ambient and internal temps at load.

Not at the quality level of Caselabs, but for <$50 not unexpected.

There are a few but you wont get positive pressure inside any case.
Please dont honestly think you can maintain and hold possitive pressure without the usage of loud overpowered high static fans and silicon sealant.

The case would need to be well sealed and with that many openings, that aint going happen without using rubber/silicon seals. (or a U Rack where basically the entire shell is one frame.)

You can also look at bitfinex prodigy series, as well Fractal node 304 & Core 500.
There is also the thermaltake Core V1 which is a very open case.

The one you probably want tho is the node 304 or core 500, as it has all the bells and whistles your asking for including the filters.

Good point about real positive pressure, @aigomorla. I'm glad you're the one who had to go negative on the positive. ;-)

My Silverstone FT05 gets pretty close to the positive pressure points - filtering dust while cooling well. Until you turn it off. Then the dust just settles down into the open top (back) as does the cat and her fur.

Those itx cases mentioned are good, except to use a mATX board in those will require a hacksaw mod to the motherboard. The TT V21 (big brother to the V1) is another good mATX case option on the cheap. Possibly the closest to the caselabs in function - just not in quality.

Thanks guys.

I put them all in a spreadsheet. The big draw for the Bullet BH4 was it's small size, that the dual chamber design potentially brings to the table. It's only about 22 Liters, with a nice clean layout.

The other mATX dual chamber models mentioned are >40 Liters.

I think I'll drop back to my mATX fallback. The define Mini C. It has all the characteristics I want, but I was hoping for something smaller (it's about 36 liters).

I plan to set it with only intake fans first and see how that goes. That should be positive pressure. I don't see why it would need rubber seals. Just more intake than exhaust.
