Are you buying a monitor: I have an old http://www.newegg.com/Product/Product.aspx?Item=N82E168... which will be used. 1680x1050 resolution.

Additional Comments: I plan to build my mother a new computer for her use at home. She is a school teacher who is about to start back to school, so time is of the essence for me here. I will be ordering components tomorrow and build the weekend after-next. Please review and let me know if you see any red flags or any better deals. I've built about 5 computers over the last 10 years and feel comfortable building them, but I do not stay current with parts.

Any alternate suggestions to save money or get better value for the money would be appreciated. Her computer which is currently having issues was purchased from a store and I really don't want to figure out what is wrong with it.

Any suggestions for a comparable 100 GB SSD would be appreciated.
