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

[ѕӎѳѳҭңӌ]

Oh damn it i didn't remember the voltage right, 12V pins are 30V with no load (in nervouschimps pic they're 25V which might be the lowest voltage with hi load.)... My bad with that one
http://pinouts.ru/Slots/ieee1394_pinout.shtml here's firewires pin out if it helps a little.

lol thats the page i was using. shal i just stick the white one in pin 1 for your board? will that work?

Well yea if you have the other pins right...
Btw you've the cable coming from front panel right? just an btw

Finally, the Mailman has arrived. what he got? Well, let's see:



A 2,7 GhZ Dual G5, with all guts in it, exept Superdrive and Harddisk. Sadly, the Logicboard is foul. So, lets make a nice HackMac out of it. First, Take it apart:




Apple-Salad anyone?

Then pry off the Mobo-Standoffs. Just a swingle with the Pliers, and *Pop* no more Standoff:






Time to whip out the Saw, and get of the faulty Logic-Board, of case exept of this little Stripe of happyness:






Fits Perfectly.

Now lets make a G5-Like DVD-Drive. How? Well, first solder a white LED in it in place of the boring green one, and build a "Emergency-Eject"-Switch at he Back of it. Later i have noticed, when you Press on Top of the Front-Left of the Drive, it Presses the Original Button (It's a LG H22N SATA-DVD-R)

Okay, whats Next? Right, the New-Old Motherboard-Standoffs. I screwed them onto the "Stunt-Double", and Superglued them in Place on the Tray. Then i unscrew the mainboard, and *tada*, all Standoffs in Place, where they have to be. Just make a little Epoxy-Glue-mess now, and they are Perfectly in Place, withstanding the next Nuclear War:



I Love "5 Minute Epoxy Glue"



Im just now Installing the Motherboard. Tomorrow i have to buy a thinner soldering-iron. The one i got is to weld something like rain gutters. No good Idea to solder the Backpanel with it, and, well, my Logic Boards are...well, out of Stock

Stay tuned for more

i have the cable coming from the front panel into your PCB. then the internal firewire header cable i bought only has 7 wires inside it. so i have connected all of them up, 2 grounds and the 4 wires for the twisted pairs, but i only have one wire left, the white power wire. if that helps you understand. bit puzzled with that really, but im not very good with actual electronics.

thanks!

Looks good

well, i have had possibly the best day yet on this project, and then possibly the worst ever!!

first off all i got everything in, and ready to go! all the parts, and then the watercooling bits and bobs. filled the loop, and went to start the pump....... not so good! its appears to be DOA!!!!!! so whilst fiddling round trying to reset it as per aquacomputers guidelines, i knock off a hose! so there was UV green coolant everywhere. so not so good. then my gpu block started to leak, but not on the fitment, on the actual block.

so i decided to drain it.... which was messy! it took me 3 hours to put everything in the system, and 5 hours to take everything out, and dry it!

cannot express how gutted i am, but i need a computer, so i set it up without the water and i am typing off it now! the feeling from going from a dell mini 9 1024x600 screen to a 30" 2560x1600 is amazing!

anyhoo, i am in discussions with aqua computer about my pump, so its gonna be another 4 weeks before i get another shot at building it fully again!

oh and (xs)solid, the pcb works brilliantly for the switch and led, but usb wont work... and neither will firewire. I was expecting that one but i would like usb. ill have a couple more plays!

EDIT: Please see attached screen grab! i have tried the usb header both ways on the pcb....

That's interesting, either theres a short circuit on pcb or something like that since it gives over current error... If you can take good picture from pcbs backside i could check is there problem with my soldering. Tho if you know somebody who works with electronics, ask him to check for bad solders.

I've tested USB, led, button and audio and those worked, but haven't tested FW since lack of time. Will look foward for that at this weekend...

so using your pcb, the firewire isn't necessary for power ground?

Power ground?
Mostly i just ment that i need to check the pinout

I'm confused because nervouschimp has written else where in this thread that the front panel connector uses the firewire to ground the power button... did you wire that differently somehow? I am a noob :-)

i think, due to the way the pcb is designed, it can get ground from a number of places, though i may be wrong. I do have firewire plugged in, so it is possible that i have the ground grounded even though the rest of the firewire doesnt work (if that makes sense)

I have got firewire to work in a fashion. it powers my isight, but os x does not detect it. ill have a look at the back of the pcb when i get chance!

Led, power button and FireWire share the same ground, usb has it's own.

If it does give power to a device it's good, maybe the TPA or TPBs are mixed and it causes the problems with FW...

Hi,

i´m new and like to start with a modd, just got the case....

My budget is about $500 - 600 and i like to modd it as a PC (sorry i know...)
but for more i have no money...

I like to know if i can use this Motherbard and how you guy`s thinking about this?!

ASUS P5KPL-CM G31 1600FSB

I also looking that i buy a like custom made PC over ebay and installit then in the new Case.

What you are thinking about? I listet all parts in the picture, is this ok for $450?

And what would you recomment?

Thanks - and you guy`s made a really good job!

x-solid, if you start from this post earlier in the thread and read the following 4-5 posts, it discusses the power/firewire ground issue I'm talking about... http://www.insanelymac.com/forum/index.php...st&p=614504

I'm wondering how this factors into the way you set up the PCB... let me know what you think!

thanks,

Wes

his pcb i think, uses the ground from firewire and distributes it to the power switch ground and led ground. this would explain why i can use the switch and see the led, as i have my firewire almost wire up correctly, just an error with one or more of the data cables.

please correct me if i am wrong however!

Can anyone tell me what type of screws are used on the motherboard standoffs? I have removed the standoffs with pliers and plan to remount them with jb weld, but I need to find some replacement screws first. Thanks.

Am I better off with a mini atx or a regular atx mobo with this tray (which honestly I think is ugly, does anyone know of a nicer looking one?)

[Gunner_Sr]

Wow, I love what you guys are doing here. So I have ordered my G5 case.

What is the cooling like with just having the two back fans (not sure on what size I would need though) and a stock Intel CPU fan?

Next, I am looking at what to do with the back ports panel, that is, the right approach.

I like the daughter-board approach using the connectors from a G5 board, but it looks way to hard and time consuming. I am not keen on using a whole motherboard tray with backplate. I have seen someone do a hybrid approach. Which is what mobo manufacturers do, that is supply a custom port plate to that mobo and you insert it into the backplate of the case or MB tray.

My question is how would it look if I took that approach, I want to keep the two fan grills in place without cutting too much?

BTW - (XS)s0lid - are you still making/selling the front panel PCBs, etc. If so, can you PM me I would like to get one?

Thanks.

Hi, I´m thinking of getting a G5 case, and I was wondering on where to get it in Norway or in Scandinavia.

Hi, I´m thinking of getting a G5 case, and I was wondering on where to get it in Norway or in Scandinavia.

Your best bet is a reseller of apple parts in your country, or you could try ebay and see if they ship to your location. The cases are a little heavy, especially if you want the power supply as well.

Cheers.
