Budget PC for BC2?

Ok, as part of my many sins, I built computers as a hobby. I've received a very interesting request and figured I might just as well ask your guys views on this as well. I have a budget of R10k to build a complete system. The only stuff that is EXCLUDED from that budget is

- A HDD (use an old one)
- A Case (use an old one)
- A keyboard (he have a gaming keyboard already)
- Mouse and mouse pad (he have a G5).

We need the following:
- MOBO
- PSU
- GPU
- CPU
- RAM
- Monitor (preferably a 24")
- Operating System

Now, my restrictions are:

1. It should be able to play BC2 at reasonable frame rates.
2. It should provide a reasonable upgrade path
3. It should last about 3 years
4. I want to keep my profit margin at around 5%
5. I don't want to overclock the PC at ALL! (stability is a much greater concern for me)

Given the above, what do you all think about the following 2 systems:

All the above prices includes VAT and my 5% profit. Now, I would really like to increase the graphics card to the 58xx series, but the price difference then just starts to exceed it too much. Also, without being able to confirm it, I would imagine on the above systems, the CPU will be the bottleneck in any event.
