Is this $170 system good? (Have case, psu, 'mobo', keyboard)

I am planning a system for $170 with scrap parts. I have the power supply, keyboard, monitor, and os (Vista 32bit). I am buying this stuff (or your suggestions) in about a few days. I am going to use this for html editing, surfing, BF 2 is probably the most intensive game. Here is what I have:

Processor: AMD Athlon II x2 (55 dollars)
Motherboard: sorry to be generic, a AM3 (link) something like that. (hoping $60-70)
Memory: DDR3 1-2gb (which one?) ($20)
Hard drive: Seagate Barracuda or Western Digital Caviar ($20)
Video card: integrated (4200 maybe)
Total cost: $165 max


Sorry if you keep seeing me delete them, it's on accident, I promise!

I am wondering if
1) Would this junk actually boot?
2) Would it be worth my money?

Thanks in advance.
