TheBigNoob's G5 Mod Worklog

[kiwisincebirth]

There's no denying Dschijn, your mod was the inspiration for me to do that. The lian li hard drive cage is an excellent product to conceal those sata connections and consolidate power cables. I was so surprised how snug everything fits together.

I'm going to be modifying motherboard cables so they are shorter and won't interfere with airflow tonight, hopefully everything everything will be done by end of night.

Have been following you work, very impressive, am looking forward to your next update. BTW I did the apple PSU conversion also, and from what I have read looks fine to me. I wrote about it my G5 Worklog (link in signature), toward the bottom of the first page. I also used the 4 bay Lian-Li drive bay in my build, notice you only use three bay any reason?

Thanks for all the positive feedback guys! So basically it's ready to be done but there's a catch that might force me into buying a new power supply. It appears that the 135mm fan with my modxstream has a safety mechanism that prevents the psu from staying powered on if it's unplugged. I've tested the power supply and all the numbers are right, but if that fan is unplugged then the power led just blinks and refuses to power on the computer. In my infinite and sleep deprived wisdom this morning, I managed to rip the leads out of the fan when I was soldering basically rendering the fan useless. I've tried using resistors to trick the psu into thinking the fan is plugged in, but to no avail. maybe somebody has some ideas as to what to do to trick it into thinking it's there, else I'll be running to mircocenter tomorrow for a psu that is a little more "mod" friendly.

Why only 3 drives? I have amazon prime and that's all I could find that and I don't really want to use the marvall chipset sata connectors, so if it gives me the ability to add another 3 for all 6 intel sata ports in the future.

Does anyone have any ideas on how to remove jb weld? worse comes to worse, i'll just dremel the psu mounts off.

here's some pics of what it would look like completed for posterity's sake

Can you not attach one of your new fans to the fan header plug on the PSU board, then you wont need to trick it, cos it will have a fan.

Fans really only come in the 3 basic configurations 2,3, and 4 pin. Its only the 3rd pin that provides any signal back to the computer (tachometer), so the only thing your PSU can measure, except maybe the current draw (but I think you have rulled that out).

The vandalised fan, how many pins did it have, three? I looked for the spec sheets for you 60mm fans, but what wasn't clear was the number of pins on the connector. If it has three pins you should be good to go.

I can, the catch is that it's a 2 pin style D female connector, so I'm waiting on the linked adapter to arrive to plug in some fans into that, also I have some 40mm noctua fans to put inside the psu housing to help push air out of the back.

said adapter

and fans [got 3 of them]

I figured i'd need the fans and if the adapter doesn't do the trick, then i'll be looking into a psu that's a little "dumber" when it comes to safety checks. I've noticed a lot of people used fractal designs/corsair psus for G5 mods, might opt for one of those if it falls through.

Clean work so far!

Removing JB Weld is actually not that hard....doesn't have much shear strength so give it a good side swipe with a hammer and a screwdriver and it'll come off pretty easy.

JB Weld is one of my favourites but in the end it is strong but not bullet proof.

Sure thing, a flat head and hammer took it right off. I ended up removing the OCZ ModXStream in favor of Corsair's CX600M. I have it functioning correctly, but it seems that my motherboard has shorted out and is currently in route to gigabyte for repairs. The good news is that the power supply is completed, correctly now. I have tested it on my two other machines and it seems to be working fine. I'll be going back into the psu to clean it up a little more later this weekend, I'll post and update showing the progress soon.

Just got to wait on the fixed motherboard!

I love the white psu extension cables. Thinking of doing the same with my mod

Looking very good

Final Update!

After hours of testing it turns out it wasn't a dead mobo (doh!), I had actually fried my ram. Thankfully RAM is the least expensive component aside from a optical or spinning hard drive, and the 2nd time through I knew to buy the low profile Corsair Vengeance RAM to ensure that the Noctua DH-14 Heatsink would fit correctly.

I've kept the computer running since friday and there has been no indication that power supply is defunct. when it's all said and done, this thing is a beast. Some final glamour shots, if there's a mod that see's this could we move this thread to the completed mod's sections?

Really gives your an idea of how close everything fits together

Nice work! I'm very happy to found your G5 Mod because I was planning to do exactly the same mod (ATX PSU to Power Mac PSU housing, use exclusively Noctua fans, buy the mod kit from The Laser Hive and use fancy cable sleeve) but with ATX (not mATX) kit and mobo.

Actually, do your PSU still correctly working? Do you have any suggestion to make to any other noob (like me) who want to rehousing the G5 PSU?

Also, with 10 Noctua fans + your GPU fan... what about the noise?
