I am looking at buying a new 27 inch iMac. There are a chain of stores in the UK called Stormfront. They are an official Apple reseller and offer a 3 year guarantee as standard for no extra cost. I phoned them asking about the iMac I was interested in but wanted larger memory on the graphics card, 4gb instead of the 2gb standard. They told me I couldn't have it because it was incompatible with Fusion drives and would need to buy the SSD version to have the 4gb graphics. I argued the fact stating I could buy one off Apple right now with the spec I wanted, they went away and checked. After a few minutes I was told to come in store and order what I wanted and they would 'mark' the order and have it custom built in their Tech office. I assumed they were just a conduit for Apple so would therefore order it from Apple. Anyone had any experiences good or bad with Stormfront recently? I felt a little uneasy at the lack of Apple product knowledge by the staff technical or otherwise. I have been in there once 2 years ago when my current iMac had a HD recall and they seemed ok at the time.
