How to fit PC in a G5 PowerMac enclosure :> Options

[teknojunkie]

hey that motherboard looks like the g5 one in color haha.

Wow I just notice that sweet

[HacOSXuser]

haha yeah when i looked it at i was like wow thats pretty nice. my motherboard sticks out cause its purple hah. how much did that motherboard cost you? is it SLi Ready?

[teknojunkie]

Yes it is Sli Ready It Cost me $120 for 2 of them fully supported for vanilla kernel and onboard intel GMA950 graphics

[HacOSXuser]

how many gigs of ram does it support? core 2 quad?

[teknojunkie]

4 gigs and quad but im not gonna rig it that much maybe a core 2 duo and 2 gigs of ram im gonna use it for graphic designing backup pc because we have a mac book air and a Mac Pro no pc's and I hate the pc case looks and so basically dual boot xp and leopard and med gaming. the mac pro and air arnt mine my brother and my dad so they dont want to get me one so im building one :DAnd Nervous Chimp if read this can you show me a pic of your front panel cabling connected to your motherboard thanks

[HacOSXuser]

seems like a nice build. good luck.

hey nervous chimp, you getting any progress done?

[nervouschimp]

hey nervous chimp, you getting any progress done?

YES! I have made progress! I got my drive bay fans wired up and working.



OK, what I did was split the power into 2 molex connectors that will allow me to attenuate the 12v and 5v separately in order to keep the fans quiet. Basically, the 12v and 12v ground from both fans run to one molex, and the 5v and 5v ground run to a 2nd molex, that way I can easily connect a voltage controller each line and tweak until I get the right combo of noise/cooling. I am hoping that I only need a controller on the 12v line.

BTW, I was unable to power the bay fans on just 12v power. It required both the 5v and 12v lines to make them run.

Also, just like AquaMac said, the voltage lines are on the outside and the grounds are the 2 inner cables.

Nice work there nervouschimp, you are right, you only need to attenuate the 12 v feed. I used a couple of Zalman controllers with one of them turned down as far as it would go and the other slightly faster. They need to be set at slightly differing speeds to stop them creating harmonics.

Oh, crap... so i will need to run a separate resistor to each 12v line?

Do you have any diagram of this or any thing that can help me out you are so lucky you know how to do this type of stuff I want to learn lol

look at the end of connectors with the notches facing up:

left to right:

12v, GND, GND, 5v

Edit:

So I just connected both power lines to 5v and now the bay fans are actually pretty quiet.

so for quiet operation:

5v, GND, GND, 5v.... and no need for a fanmate!

Sweet thanks this one is for the harddrive fans right? or for any with foraand do I need a solder or can I just twine them up

this is for the drive bays fans... both have 4 wires.... i am not using any other stock fans so.... can't help you with anything else.... but they are prolly the same... just connect them 5v, GND, GND, 5v..... the lowest that most fanmates will go is 5v anyway.... so save some clutter.....

i twist, then solder, then shrink-wrap, but i like it to look pro, and be permanent...

So thier is 2 fans on the drive bay and also how come on the molex connector the other 2 wires are gone

Where is the best place to get one of the G5 cases?
I'm in Sydney [Australia] if there is a place a little more local...

Could I use the molex Connector for this one too

Im an Idiot I made smoke come out of the fans does that mean they wont work s**t

[CZ*DarkLight]

amantheboy08: smoke and even sparks? Yes, I ended up with this too. But dont think that the fan is gone, it will probably work with right wiring again... Mine ones work!
