Preliminary specification on the second generation HDPLEX H5 series fanless computer case

Preliminary spec for the the second generation HDPLEX H5 series fanless computer case.
(These are final)

Dimension:
Internal : 75mm(H)X338mm(D)x360mm(w)
External : 430mm(W-Faceplate)X88mm(H with feet))x353mm (D)

This 430mm width is based on many request from audio PC customer.

Each H5 chassis will come with three HDD racks.
Each HDD rack supports three SSD/2.5’HDD or one 3.5″ HDD+2SSD.

Dual slot card is supported.

Hard PCIEX16 Riser is supported for ATX motherboard. (Use the 2nd PCIE slot on the motherboard)

Port:

Right Side:

Dual USB 3.0 and DC 12V Output with 5.5/2.1 DC jack for External HDD. (This unique feature allow user to connect 3.5″ External HDD from Seagate/WD/Toshiba without the need for another AC-DC adapter)

Left Side:
Dual USB 2.0, Power Button, Power LED, Speaker Output 3.5mm Jack

H5.S exclusive feature:

There will be a special designed power button in the middle of the H5.S faceplate. This aluminum power button is 38mm diameter, allow customized laser engrave logo. (Hello Steam Machine logo? ;))

The hidden power button board use MCU to control eight blue LED and provide three lighting modes (full light/half light/no light 60 seconds after powered up).

This power button will become a signature of HDPLEX chassis. It will also appear on future cube style NUC chassis and even H1 series.

Heatsink System

CPU Heatsink system is redsigned to support 8 heatpipe solution. I believe this will be the first 8 heatpipe cooling solution on the market.
The aluminum top plate will have fin just like the first generation.
The new copper baseplate is much taller.This greatly improves the compatibility. Motherboard with VRM heatsink or ATX 24PIN port on the side won’t block the heatpipe path.

The new HDPLEX 8 heatpipe heatsink system should support CPU with upto 125W TDP.

Optional HDPLEX fanless video card heatsink system.
This video card heatsink system also features 8 heatpipe.
The aluminum top has fin as well.
It support all popular mounting pattern for video card from A and N.
(43×43,53×53,58×58,61×61)

This passive video card heatsink system will support low power card like GTX750 with ease.

Power Supply

The second generation H5 of course support my 160W and 250W DC-ATX module and newly designed 90W AC-DC module.

The new H5 also supports dual internal 90W AC-DC module +160W or 250W DC-ATX combination.This fanless power supply combination can handle most mid range system with video card like GTX750

For third party power supply:

The new H5 will provide an optional SFX ATX PSU kit(rack+IEC extension). Users will be able to install SFX ATX PSU internally when using motherboard which width is less than 22cm. There are many microATX and ATX board with width less than 22cm.

SilverStone has a 600W fully-modular SFX Power Supply.

If you don’t mind passive, you could certainly use ITX motherboard+Titan+Silverstone 600W SFX ATX PSU in H5 chassis.

The second generation H5 chassis is a dual purpose chassis…Devil

I myself don’t care about gaming but where is the HDMI 2.0 card?Mad

The new H5 will feature an optional ATX bridge board which is installed on the back plate. Users can connect modular ATX power supply directly to this board. So changing power supply is never so easy:p

Should I say I am the first one to invent this ? :p
I hope this ATX modular bridge board will be useful for some customer who has to use ATX PSU and full size board in my H5 chassis.

IR

I have updated the IR receiver PCB. It has a filter and much better sensitivity. The IR head is also vertically installed on the PCB board and should have better reception.

The IR PCB will be attached to front of the H5 bottom plate via one M3 screw. The IR head will be outside the chassis like H1. But it will be invisible.

I really can’t wait to release the picture soon enough.
Some module is taking forever…Fire

More on the dual 90W AC-DC module with 160W/250W combination:

Some factories put two DC input on their high power DC-ATX board.
Their design is basically use one AC-DC adapter input to support 3.3V 5V rail and the other adapter to support 12V rail. This design works but might not to able to balance the load between the two AC-DC adapter if the main power draw is on the 12V rail.

My solution is different. It didn’t add one more DC input the 160W or 250W DC-ATX board. I designed a new board with dual DC input and single DC output. This board will dynamically balance the load between the two 90W AC-DC adapters.

Last, there will be H5.ODD which support 5.25″ type ODD.

The new H5 is quite a complex project. It takes very long to design and perfect. I think I am satisfied with the current result and I myself can’t wait for the release.
