Hello. So, all this chat of fusion drives has gotten me a little green, so I've been considering upgrading my iMac with a SSD to boot the OS on. Now, I've not opened one of these things before, and, frankly, the prospect of ballsing it up and writing off my beloved machine is too traumatic to contemplate, so I had a look around for AASPs to do it for me. Anyway, got quotes back for the drive and labour of the following: 128 GB £178.80 256 GB £214.80 512 GB £398.40 The big one's probably out of my price range, to be honest, but for the other two, does that sound like a good price? Do you think it's worth paying for the labour, or do you think I should freakin' man up, rip the bastard open and do it myself? Thanks for your time.
