(I don't have many pictures for this one, so you all will have to trust me.)

While dropping off a couple electronics at the local recycling center today, I noticed a 23" Aluminum Cinema Display in near mint condition sitting near the computer drop-offs.

Rather than let it go to waste potentially unnecessarily, I decided to take it in and see if it worked (hey, you never know). Of course, it was only after I started cleaning it up that I realized it needed a 90W power supply to run, and all I had was a 65W from my 20". So I went back there, hoping to find it laying around someplace, but couldn't find it anywhere at all (go figure).

So when I then ended up following this trick online (http://www.fixya.com/support/t2630438-apple_cinema_display_23_led_short_long), I got it working with the 65W supply as a temporary solution until I can get a 90W in. Then, after hooking it up to the G5, it appeared to be in complete working order.

Needless to say, I'm very happy I was there to save this guy from certain doom - and upgrade my desktop in the process. :)

Very nice find!

I have the same model, which I got for €5 as the owner couldn't test it due to the lack of a PSU. I made my own with a 24V LED supply and a power connector out of an old Mac Mini, and since then (about a year ago now) it's been my main display.

These displays are stupidly color-accurate once calibrated. I've attached a report from the last time I calibrated mine.

I'm rather fond of these aluminum displays. AFAIK, the basic panel is the same as the ones used in the acrylic displays(at least the PPI is the same) but you get a USB 2.0 hub, FW hub, and the later ones have brighter backlights. I use a pair of 23" aluminums on my MP 1,1 at work.

I've never owned a "proper" PSU for one, and in fact I've been told that sometimes the 90W won't properly power them due to the aging backlights drawing more current than that. I cut the plug off and use a 24V LED transformer with all of my cinema displays. The 23" ones run on a power brick type, while I have a somewhat more "industrial looking" one with screw terminals and a metal case(which reminds me-I need to by another as I inadvertently shorted and killed my last one-using myself as a ground path via a G5 case-that was a fun experience).

I use a newer 27" Cinema display as the primary with my 5,1, but I still definitely have a soft spot for both aluminum and acrylic.

I have the 20" and 23" aluminum displays. The 20" works like a brand new display, the 23" however has been moved to the second display due to a weird vertical line pattern appearing. I really like the hub on these displays.

They are gorgeous displays indeed. I bought my 24" Alu Cinema Display 2 weeks ago. Unfortunately it has 2 scratches but they are barely noticeable. What kind of bothers me though is the ghosting effect or screen burn in on my 24" CD but I guess that is normal for such an old display. Does anybody know maybe if the panels can be replaced or if there are compatibles LCDs that aren't from the mid to late 2000s but newly produced aftermarket panels? I'd need one for my 20" CD because it has a rather big (1,5 centimeter diameter) white spot in the lower right corner which is annoying. It is however less noticeably when viewing from an different angle. IMO it is extremely hard to find an Alu Cinema Display in immaculate condition :( But then again these displays are turning 10+ years so I guess the wear and tear is normal ... Congrats to the OP on the score :)

I gave my 23" Cinema display (the last matte display) back to my university (I got it through a grant) last year, but that was after nine years of stellar performance. My favorite display of all time. Such a joy to work on.

I use a 23" ACD on my Mac Pro at home for gaming; it's wonderful to have the extra vertical space that it offers as compared to a 1080p display, the colors are amazing, and it's just overall a beautiful screen! I also have a pair of 20" ACDs, one attached to my Mac mini at home and another as the second display on my iMac at school in my classroom.

I had a 30" and a 23" model when I had my Mac Pro 4,1, they looked great both in terms of colour and aesthetics. The downside was the power draw, my electricity bill noticeable went up (mainly due to the 30") so I ended up selling them and getting some dell ultra sharps with led backlights
