That board I handed him looks like rats chewed on it so I have very low expectations.

Amazing how he does so much and has time for a family. I think that trophy belongs to you, dude. You work all day, cap all night, charter yourself to Tampa and still have time for your wife and young boys.

While getting sick at the same time... 🙂

Was able to pick up a Dual 2.5 GHz Power Mac G5 liquid cooled beast minus RAM and hard drive at the university surplus for a single $20. I couldn't resist. I've always wanted a liquid cooled G5.

Well that is sweet. Good find.

Great deal! Those G5s are beasts! Any indication of the LC system leaking?

Not yet. I'll keep my fingers crossed.

I would keep a close eye on it, my dual 2.5ghz leaked twice
However if it leaks you can put a pair of the old style heatsinks on it, thats what i did with mine in the end and it's been going for 3 or 4 months now with no problems

But if I did that, it would be like my other two Power Mac G5s.

So was there anyone that did analysis on these, to figure out why they leaked,
I know the cooling system was designed by DELPHI a division of GM, looks like they basically used an Aluminum A/C evaporator for the Liquid to air heat exchanging process.
The issue with liquid based cooling systems is they will all eventually need some kind of service.
Even with the ford model T, using natural convection instead of a water pump.
I'm sure you could still develop a leak causing the cooling system to fail… or scale build up in the heat exchanger would slow or halt the
convection process.
About the worst you would have to worry about with a hunk of metal as a heat sink (passive heat exchanger) on a cpu is dust clogging it up.
oh and maybe the thermal grease drying and caking, between the HS and CPU, but i think that is just due to poor quality thermal grease in the first place.
well, maybe the fan burning out, those case fans in those G5 towers are aggressive and very good quality.

I got a hand me down from a friend tonight - Powerbook G4 1.67 high res with the box, media etc. It seems to work well so just the cursory cleaning and it will be good to go. That means I have the first G4 AL book and the last.

Nice! Those last models with the Hi-Res displays were some of the best AlBooks Apple made, IMO.

Picked a 4th Gen iPod Touch with a completely smashed screen for free. Just ordered a cheap replacement for $28.

Make sure that display you ordered is the whole enchilada. The LCD is fused to glass in the 4th gen, and the digitizer was too.
Those 4th Gen iPod touches are pretty sweet. I had one before I got my iPhone and loved it. Got rid of it after I got my iPhone as I wasn't using it anymore. Too bad they aren't supported by iOS 7.

Posted by: mcdermd on 2013-12-02 13:39:55
Yup. I've done the replacement on these before.

Nice! Those last models with the Hi-Res displays were some of the best AlBooks Apple made, IMO. What I've found, though, is that the battery charging circuitry tends to go before the rest of the components on the motherboard so you end up with a laptop that runs fine on AC power but is no longer portable which sort of defeats the purpose of having a laptop. You can get replacement motherboards but changing them is a pain. I have two of them and neither of them will charge a battery. One has a cracked screen so I put that one into a Bookendz docking station and use it as a desktop with a stand alone monitor.

My conquests are so few a far these days but I fell into a Grape iMac with keyboard. Looks like I need the grape puck and the IO door, though. Don't even know if it works yet. Also picked up a VST SuperDisk drive and a DVD-ROM for PowerBook G3 for $3 each.

Made a lucky bid on a working Quadra 950 board for $40 shipped on eBay. Hopefully that gets my Q950 up and running for real.
