I am a graduate graphic designer and I have been using imac dv for almost 3 years now. I desperatly need to upgrade..but obviously being newly graduated i have ltd money. I was wondering if anyone know any deals or good places to purchase in the UK. Also i wanted to (when i get it) network the new computer with my imac..so i could perhaps use my imac as a hardrive? is that possible? excuse my ignorance.

No offence, but look at EBay UK or a classified ad wbsite over there, this is not the appropriate forum for that part of your question. As for the iMac being networked, all iMac's have come with 10/100 BaseT Network I/O's built in, so, yes, just enable file sharing on the iMac plug in the ethernet to a hub, switch or multi port router and away you go.

Do you want to upgrade current iMac or buy a new one?

I want to buy a new one. i want to bassicly use my imac as a glorified storage unit..but a nice blueberry storage unit!

Yes you can do it really easily but when you deal with real graphic files (ie >500Mb files), you will find it really slow and displeasant to use a network drive. The best advice is to work on your local drive (in a designated directory). Make, download or buy a program that will transfer the datas from the local directory (for example /workspace) to a remote directory on sepcific hours that you know you won't be using your mac (like 4-5AM). I think that Dantz Retrospect can do it but check out their website to be sure: www.dantz.com

Probably the cheapest in the UK becasue it doesnt have a show room but you know what you are gettting with a mac http://www.jigsaw24.com
