I'd go with the above suggested build with this CPU but you could move up to the 46600+. The Brisbane runs a bit cooler and the Windsor a bit faster but heat will not be a problem with that machine. If it fits your budget, I'd go with the Antec Sonata III with the better PSU, quiet, very good PSUm and very easy to work with, especially swapping drives but more expensive that the Rosewell above, which would definitely work. I look at cases as the longer term investment because you can use it for future builds but again the Rosewell would definitely work. Using a similar mobo as the above for both my wife's and mine business machine and no problems. Both the CPU and 2GB of RAM will be more than enough for what she needs. If your networking and sharing a printer, would suggest a print server, I'm using the IogearAir and it's work with no problems. I partitioned my wife's hard drive putting the OS/program on the first and data on the second partition, don't have to worry about backing up data when you reinstall Windows. Also put a second backup drive in her machine and using Goodsync as the back up program. Given she uses it for work, back up is very important. Had to set up the machine to make it as simple as possible. Say computer and she's confused

Unless you have a copy of XP you'll need to get one, $90 for OEM. As for monitors, I like Samsung. Given prices you could get a 19" for near the same price as a 17" but their 900BF series is good. If it were me, I'd get a better monitor than you're using, unless your's is really top end, and give her your old one

She'll definitely get a much better machine if you build it and you'll save a little money. Most woman seem to be into saving money, which could be a selling point plus parts have much better warranties than systems. Usually 3 - 5 years depending on the part and lifetime for RAM.
