This might be a side note, but I think with video editing it is quite highly affected by the monitor you use and getting a nice IPS over an LCD would be beneficial for better viewing angles. Also make sure you get one with high contrast and good colors out of the box. Putting a nice screen on top of what these guys have suggested as a PC spec, you'll have a wicked setup for photo editing and music.
All that said IPS panels are expensive, the Dell U2410 is one of the best atm i believe but your looking at spending as much as it'd cost to make your PC!
for a decent price and amazing contrast the Samsung SynMaster F2380M is probs your best bet
Just something to factor inGL with it!
If she would have said it was for work I would have said this screen

Dell UltraSharp U2410 24" Widescreen LCD Monitor - Midnight Grey **REV A02** will cost £459.98 inc VAT ...

Also the Samsung SynMaster F2380M has no HDMI connection which may come in handy with a person doing video/audio creation.
