I think I would consider a different hard drive. Weren't the deskstars known as deathstars for a while? Hard drives aren't that exspensive anymore, and IDE 80 gig 7200 rpm WD, should run about $60, how much is that deskstar? (Note there isn't a performance differance between ATA100-133)
As someone else said, that video card is completely pointless. Yes a better video card does help speed up the system a little, but for an office PC, just use on-board video, save yourself a chunk of change.
I would either pick a different heatsink, or just buy a retail processor (Heat sink included). Plus with the retail chip your get a longer warranty.
As some one else said a CD-RW drive would only cost a you a little more, if any extra, and would be handy for creating backups of customer lists. Those Sony drives aren't the fastest thing on the market, I know, I ditched mine a couple of weeks after I bought it. CD-Rs aren't the most reliable for long term storage, but it would make backing up customer lists and such very easy.
Next whats the deal with the $100 dollar case?? That really isn't necessary, especially when trying to build something cheap. You can get a case that will cool great and is sturdy for $30 or so.
For example, I've used several of these case for PCs I've built for people, they are sturdy, offer great cooling, and heck most of the time when I buy them they include a free keyboard and mouse. This case also has a good power supply in it.

Then whats the deal with the NF7, you are building something cheap, this isn't necessary. That NF7 is kind of pointless, especially with that CPU. You would be much better off getting an MSI board, they make good stuff, and will be half the price.

In my opinion you went cheap in the wrong places, and exspensive in the wrong places, switch them back around, you are building an office PC.
Also keep in mind most of the prices I listed where prices that I would pay at my local PC shop, online they should be cheaper.
Also 256 MB ram is what I consider the very mininum to run Windows XP, maybe you could save some money by methods above, and add another 256 chip in there.
I have been hearing many complaints about dead pixels and such on the flat panel displays, so choose carefully.
Hopefully this helps some.
