Updated Graphics 4 Days Powermac G5 Mod (HD7870)

At first: Hello tonymacx86 community.
In this thread I will show you my modded Powermac G5.
I made this Mod in about 4 days and a full work time of ca. 40 hours (maybe some hours more, I'm not really sure).
I started on Monday at 6pm and was finished yesterday on 4pm.
My aim in this mod (by the way my first mod ever) was to use as much of the original parts as possible.
In this 4 days i modded just the mayor parts of the case.
There are some little things to do like soldering some wires for the fans etc.
Accidentally i got no pics from the modding process.
Pics are going to follow soon.

EDIT:
Here you all got some pics.
As i said, I'm not completely finished.
I just finished the mayor part.

EDIT 2:

Also the plastic thing for better airflow fits.

EDIT 3:

Some new pics, i run the wires a little bit better and removed the "Cold Cathode Fluorescent Lamps" that you can see in the video.

as you can see, i modified the back fan holder to fit the main board ports on the back.

the back fan holder now fits very close.

in this picture you can see were i used my dremel to make it fit with the main board (this is the metal plate between cpu and graphics card).

SHORT UPDATE:
added cpu cover, also i got a new cpu cooler from which i will post a picture later.

Love it! If all goes well, should be finishing something similar this afternoon. Minimal cutting and maximum performance!

Questions:

Did you re-wire the mac PSU or did you retrofit a new PSU in the mac PSU case? My PSU was not able to supply enough current to power my hack, so I'm off to retro fit another in the G5 PSU case.

Did you wire the dual fans to fixed voltage, or were you able to run them to the motherboard fan control outputs?

You might consider cutting the IO shield and installing it with some blocks to prevent air reversion from the back of the machine. That would improve the look from the rear, but more importantly, it would improve cooling. Also, you could block off some of the holes on the mesh in the rear, same reason, so that airflow would only come in the front and only go out the dual fan ports (at least on the bottom of the computer, I suppose you could leave some of the top open for convection cooling in case of a fan failure). Nice work.
 
Cool runnings! :D

Doesn't even look that noisy, to boot!
 
I fit the psu from another case into the psu-case of the g5, soldered the original psu fans so they work with the new psu, but i think this system is a little bit too noisy with those original fans so I'm going to replace all the original fans with new ones.

At the moment I solder a new cable to get the dual fans working with the motherboard fan control.

Next week (when the store is opened where i can get some aluminum) i will close this big hole on the back of the case.

Just for a tip; when you purchase new fans go with (silent) Nexus ones. These are a bit more pricey but are well worth their bucks.
 
Or you can wire them to 5volts instead of 12v, for more silence as I did to my 500w PSU and is running cool.
 
I will use 12v because i also play games like skyrim (highest settings without legs) an the system would be running to hot.

UPDATE:
The dual fans at the back are now running over the motherboard fan control.

And because i got to much time this evening I eventually put some cool blue (sorry i don't know the english word) kaltlichtkathoden in the case.

EDIT:
Now i also can use the "slide to plug in" (don't know how it is really called) adapter of the cpu fan.
