I bought another HDD a few weeks ago. I was going to buy one of those cheap BenQ LED backlit monitors, but I bought a new desk chair instead and couldn't afford both. Before that, it was a 1GB 4870 after the first price drop (somewhere around £230).
I have an inch-thick stack of OcUK receipts, though. I'm just more sensible with money than I used to be and I now only buy new toys when I can actually afford them and really want them.
