If you can afford it, it might be wrth your while to upgrade form XP home to XP pro, XP home is the most horrible OS I have ever used (including Windows ME
)
I would also reccomend maybe changing the Mobo for an Nforce2 chipset (The A7N8X-U is the best I have used)
I can also reccomend the NEC drive, I use it myself and unlike Most drives it always writes at 4X (Obviously providing you use 4x or above media).
AS you say the FX5200 was requested because you dont play games so thats fine too, though if you really want to future-proof your machine it may be worth investing in a better one like a Radeon 9600 XT, I know with a lot of these cards the better ones can be had for about £30 more so it may be worth looking into (This is coming from someone still using a Ti4200 and has no intention of upgrading since its stll running strong).
