Sounds like your building the same computer I build about a year ago. I have an Athlon 3100, cd burner (that I had) DVD burner, 120 gig HDD 1Gig Kingston RAM, one of those 15 in one memory card readers & an extra 20 gig hdd I had laying around. I also bought a capture card recently to convert some Hi8 video tape to digital but haven’t gotten around to it yet.
Shop around online, I got most of my stuff from the same place as a "bare bones" system, the motherboard, processor and power supply were already installed in the case & tested. If you've never built a computer before this is the way to go.
This is where I got my bare bones system http://www.americancomputech.com/
I looked up the order # here are the specs (keep in mind this is from a year ago)
M825G+Pro3100A Series Kit 1 $191.90 $191.90

TOTAL Shipped was $208.32
I bought the RAM & Hard drive from Best Buy & Ckt. City, both were on sale at the time (with mail in rebates)
I think the HDD was $80.00 & the ram was $100.00
I got my DVD burner & capture card from http://www.newegg.com/
The 1st DVD burner I had wouldn’t work, they were great about getting me a replacement. All I had to do was ship them the broken one at my expense, which was about 3 or 4 bucks.
I'm just using the intergraded sound & video cards which work fine for me. I could upgrade if I ever need to.
The DVD burner & Capture card were each about $50 shipped
I probably have someware around $500 into my computer, I think it works great. I'm not a gamer either, I'm more of a multi tasker/TV show/music/movie downloader, this setup works great for me.
