Mac G5 Mod arg-ist

Aug 4, 2014

This time my case to mod is a classic. Powermac G5. One of the most popular and ,one of the most modded beauttiful case ever made. As robustness , ı can say it is a PANZER.

someone showed his love like ...

Some prefer to use such

Powermac G5 is one oft most modded case. but most of them, changed outlook of the case

My goals for this Project were to preserve the look of the case at outside ;and fit my PC s hardware including a full ATX MB. And watercooling.

I will to mod at two stages

First the mod on the case and and convert it for an ATX (BTX) MB …

Thenn as second mod to this case... for Watercooling… with acrylic tubing and alphacool capecora passive rads 642+142= 742

To use an ATX mainboard at this case, the back panel must be changed.

İf we wannt to adapt the case to new motherboard. We must change

At the back panel, the fans must be moved off center, to make a new I/O. and a larger room
for 7 slots

There are a lot of mods, one of them is ,

to make a half mask as Ben Katz did.

Link: http://build-its.blogspot.com.tr/2011/04/how-to-fit-your-pc-in-power-mac-g5-case.html

and mount them to thecase

Or we can use a MB tray with backpanel as gibsonc did.

Link : http://www.insanelymac.com/forum/topic/281165-powermac-g5-case-mod/

And cut the case, to make a space

And mount it

But I wannt to make a new back panel complett. With new fan holes , I/O and slots.
I wannt to use the original fangrill as well.

Drawn at corel... but ı musst make nearly 3000 circles with 3mm Radius..

And sent to water jet for cutting….

update 2 30.11.2014

İnside of the original case
To start, ı completely emtied out the case, including the latching mechanism that holds the front side panel on;

but be carefull , we must use latching mechanism.

The new backpanel came from waterjet ,
And this the new raw plate for backpanel that came from waterjet cutting

and and new backpanel bended.

Locations were determined to be cut in the old panel

marked places emptied with dremel.

Bended backplate temporarily mounted to the case

To mount MB tray ı bonded 3 piece 10x20mm aluminum profiles with Dewcon SF plastic steell.(epoxi)

MB tray (in 2 piece) mounted with standoffs.(they must be sanded, and painted)

I must make a place for PSU . to mount the PSU ı made a tray .

And mounted psu with this tray to the case

I made a duct from plexi for exhaust of PSU.

Mounted duct to PSU

And mounted the psu with exhaust duct to his place with PSU tray

This photograph is with a Corsair AX1200 photographed. İt is 200 mm long.

Therefore if ı have a problem with MB , then ı can use an Corsair AX860i . It is 160 mm long…

40 mm shorter, not to have a problem with MB and slots.

MB tray painted alu and mounted

UPDATE 11.12.2014

Original fangril mounted (from inside)

Backpanel with mounted grills (I must find 2.2 mm phillips self tapping screws fort he grill

The back panel brushed with 3M Abrasive Brush

The new backpanel with I/0 slots and fan grils mounted to the case

the latching mechanism that holds the front side panel is mounted again.

And the side window mounted with latching mechanism.
Case with closed sidewindow

I must add an white vandal buton becouse the led of original Vandals is defect ,and two leds for ON/OF and HDD.

Made 3 holes 3mm and 16 mm diameter.

Mounted the 16mm Vandal

And 3mm leds

And the new case with new backpanel

To compare.. Original Mac G5 and the new ATX compiant Mac G5- ATX

Next update is a different modified passive Watercooling, with a Cape CORA 742

UPDATE 19.12.2014

I want to built a watercooling system, for my modified MAC G5 ATX

And cool CPU+MB+Videocard. And use a PASSİVE RADIATOR.(no more fans to cool)

One loop but in two parts.as

3XHF142 rad >CPU> MB> 4X HF 142 rad>EVGA 680 Classified> REZ. >POMP

I want to see the case like this

Using a passive radiator , alphacool cape cora 7x142 mounted at rear sidewindow.

This radiators normally operate parallel .Like this

But ı want to use it as serial .Like this

Therfore ı must mod T-plug connectors of cape cora.. on the bottom.and block one side to to prevent fluid flow.

UPDATE 20.12.2014

And make special fittings (adapters) for connection on the top between cape cora and EK-CSQ ADAPTER 90

using 7 piece bended 16 mm OD clear acrylic pipes, to see color of fluid.

12mm acrylic pipe looks out very skinny to me…

I could use 16mm OD Copper pipes too… like this…in my 800D case..


but ı want to edd a little color to the case…

I planned to use EK-CSQ ADAPTER 90 BLACK

EK-HDC Fittings 16mm G1/4-black(is the best rigid fitting for 16mm acrylic)

and bıtspower case through hole fittings-black

UPDATE 20.12.2014

I had planne to use EK-CSQ 90 adapters,

But ı will change EK-CSQ ADAPTER 90 Black ,with Monsoon Light Port 90 Rotary Angle Adapter ¾ Black

and ı will illuminate the pipes from inline with Monsoon LED Stop Fitting Black(without monsoon comp. Fitting)

to get the illuminated efect with 16mm thick acrylic pipes like this

At last ı would like to see my MAC G5 case like this…with fluid color in bended acrylic pipes

outstanding work, for both cases !

So there's still some custom cut to do on the front panel for the PSU plug, isn't it ?

I don t want to make cuts on front panel. I shall make PSU plug at Back Side Window direct in to the exhaust duct of PSU.

I want to use Cape Cora as serial .Like this

Therfore ı must mod T-plug connectors of cape cora.. on the bottom.and block one side to to prevent fluid flow.

I made special stop fittings from delrin

and prevented flow of the fluid.

this is the loop of Watercooling, with serial working Cape Cora..
