So my 2007 alu 24in iMac hard drive has finally given up the ghost Asked a few local apple authorised service centres for prices regarding fitting a new hard drive and was surprised at how much they were charging. One centre wanted to charge me £130 + VAT for service alone! So this got me thinking about sourcing my own hard drive and just stumping up the £55 for fitting, but I'm not sure at all about internal hard drives and not sure which ones would be required. I'm only looking for about 500gb of storage or less. A quick amazon search came up with this: http://www.amazon.co.uk/gp/product/B000Q82PIQ/ref=noref?ie=UTF8&s=computers&psc=1 Would that be what I need? It only has 16mb cache whatever that means. I ideally want to keep the whole thing under £100. I'm only doing this because I want to sell the thing and I'm guessing not having an internal hard drive will reduce the price of the sale by quite a margin. If anyone can confirm the above link or link to better deals that will definitely work with my iMac it'd be very much appreciated. Thanks!
