I have just spent half the afternon trying to decide whether I should buy myself a shiny new stainless steel keyboard for £25 and decided it was too expensive !
Nice one Kate, make sure you put it to seriously good use.
I hate it when I see all singing all dancing top of the range, high spec PC's going to waste in peoples spare rooms. You know the ones I mean, they have to have the latest, fastest and bestest just to outdo their mates and then realise they don't really have a use for it except for emails once a week and it sits there throbbing with pent-up energy, gathering dust.
The one I use is only slightly better than your old one but plenty fast and stable enough for my humble purposes, I will wait for the new BTX form factors to become mainstream before I decide to upgrade again.
