More specifally this one - www.ebay.ca/itm/170919263968?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_1065wt_922

I recently purchased this one. I read some scary things about logic boards, blue screens and horizontal lines.. Are those just anamolies? I'd greatly appreciate some feedback. Thanks in advance!
 
I have that specific iMac and it is still running, the only downside it developed black/grey botches on the display, which were covered by the warranty but I have seen them too late (only visible with white or grey backgrounds and only on the sides).

Did not know, that it would still fetch that much money.

Anyway, I have upgraded that iMac to 4 GB RAM (6 GB is possible too) and also replaced the HDD with an SSD and am currently thinking about getting it a bigger SSD, though since it is stationary, an external HDD is always connected anyway.
 
Those don't have any problems with logicboards or blue lines. They're very well built and the only models that do have problems are the ones with the Nvidia GPU. Although there is a software bug that is currently effecting them. It causes the computer to freeze. The root cause is one of five kexts that have to do with the ATI 2400/2600 video card. This bug effects 10.6.7 through 10.8.2. Apple can fix it, but has yet not. Still a very good machine. Sadly, they may not be supported with 10.9 as they are some of the oldest to get 10.8. I use one of those as my main machine. Love it very much and it does what I want it to very well.
 
Black Grey blotches? What are they from? Do you know what causes that? Does it happen to all of them? If there is too many problems I'm tempted to just turn around and sell it right away..

Intell, that is very encouraging. Does the black and blue blotches only affect the nvidia gpu? Does yours have that too?

It was a problem with a batch of panels Apple used. If they haven't developed on your newly used iMac yet, they will not develop now.
 
I think you overpaid a bit. Plus, machines this old are losing compatibility fast, and I have seen many bricked iMacs from this generation (though mostly 24" models) But whats done is done. Its still a fine computer.

How do these computers just get shot?

The problems with the Nvidia GPU are that the video stops working entirely. The GPU in the Nvidia iMacs is the same that the Macbook Pro line has with the 8600/8800 GPU. Same GPU chip with the same manufacturing defect. The black and blue blotches are dust build up between the layers of the LCD screen assembly. Only some iMacs of the 20" and 24" models get it, but most of the 21.5" and 27" models have it. It can be cleaned out by disassembling the LCD screen assembly and cleaning it. Then closing it back up and sealing it better than the OEM seal.
