Is 2017 5k 3;5 24gb 256 SSD much better than the 3.4 one? I can get the 3.4 one with a 512ssd and same ram for £100 pound less than the 3.5 one plus a one-year guarantee not from Apple. Is there much difference between the models?
I got in touch with the seller with the 3.4 one about whether it came with an original Apple box. I made a mistake mentioning who would want to buy one with a Fusion drive. He got back to me saying it did,t , But he put the price up by 50 pounds.

I can only think it was my message about a fusion drive that he put the price up. I thought I would get back to the other seller, saying it had been on there some time and would he accept 50-pound less than the price he had on there. He agreed so I have bought that one, As it was now the same price,, although a smaller SSD, I will put the OS on an external 2M 1 TB SSD and half for Windows with Bootcamp.With this enclosed

iMac is in Excellent condition with no marks / scuffs
This Apple iMac is in Mint condition and complete with the original box. It was a customised upgrade, that would cost £2,699 if purchased from Apple Direct. It has barely been used - bought for freelance work and no longer required and not used to its super-fast capabilities so no longer keeping. It should be
good if it is what he says it is.
