Greetings. It is sad but I need to sell my old computer as I have no space as I have just upgraded. I need advice on selling a power mac G4 mirror drive, dual Cpu 1.25ghz with firewire 800,2 gigabytes of ram (selling)with one Apple 17inch studio monitor screen, the apple keyboard (which was white but has turned to a cream kind of colour)cannot find the Apple mouse, the recovery disk and manuals. Not the original ram and no box. It also has an Apple Scsi card installed. At the time of purchase the G4 cost roughly $5000 just over 3000 UK sterling(using today's currency) with 2 apple studio screens. I also have an additional Tiger OS CD with it. The hard drive is the same hard drive that came with the machine. It is amazing how it still works. The DVD/CD writer drive can only read disks but will not burn to disk, how much does this take off the price when selling? I have a decent soundcard as the G4 was a workstation for music. It was the delta1010 PCI card. I have seen prices for these and they go for about £100 and upwards How much could one expect to sell a G4 power Mac? On Ebay they are going for about £130 about $211, one G4 I saw was for £180 about $292. My G4 has a lot of dust inside, how does one clean it properly? At the bottom at the front in the corner inside of the Mac there is so much dust I cannot believe it But I cannot access it because above it there is the DVD drive it is all connected together. Is there a website one can recommend or videos or any advice? Would be appreciated. I was thinking of using one could use some kind of air gun. Though I think someone who deals with making and taking computers apart would be best. I really have no experience in taking apart computers. It needs to be clean to make it function better. The G4 still works but it needs to be cleaned for sure. I was going to sell the G4 with the soundcard for £50 about $80 but seeing those prices I may change the price. Any advice on this would help. Thanks and have a nice day.
