New hard drive (what brand to get)

[demon]

I decided to do some number crunching last night and I found out that the difference is about £4 (that would be the total with the delivery costs added and is less then the 3 day lite delivery option that I would be able to use at misco for this order) but then I did get that external 160GB hard drive about a year ago and it is already half full now (but it won't be when I get the new internal hard drive) do it'd be better if I forked out the extra money for the extra 70GB.
Besides I've already got the one critical part I need to get this all working (since if I hadn't then I wouldn't be able to supply power to the new hard drive)
