Doing another build for a friend, looking for advice

[MPTech]

I built a system for my neighbor about 1 1/2 years ago and now he's asking me to do another build for him (for his 17 year old daughter, he said her PC is old and "broke"), she's not a "first person shooter" type and no heavy processing requirements (takes digi pictures, but no heavy movie editting or anything).

I built him an inexpensive:
XP Home SP3
MSI K9MM-V mobo
AMD 64 X2 4000+
160g SATA
2gb DDR2
450w PSU
XFX GeForce 6200 / 256mb DDR2 / AGP 8x
all totaled it was under $400 (he had XP already)

he really liked it and wanted the same for his daughter. I told him I'd try to keep the price about the same, but he'd probalby get a better / faster PC for his money now than when I built the original.

quick search I found:
Biostar TA780G M2+ Barebone Kit - AMD

Biostar TA780G mobo
Phenom X4 9500
2GB DDR2-667
250GB SATA2
300w PSU

seems like a good deal, but I haven't worked with Biostar before, the reviews said the CPU was good, but there are faster dual-cores (!?!?!) for less money and the PSU seems a little weak.
(anyone want to weigh-in on the faster dual-cores?)

Any comments or better suggestions for his build? thanks
I wanted to keep the build around $300, because he still wants a 3.5 floppy (can't let go), front card reader, wireless network card

The PSU is way too small at 300 Watts, and won't allow any room for future upgrades at all. The X4 9500 is a good, and reasonably priced CPU, but you'll get better performance from a Core 2 Quad, and for very little extra.

I agree upgrade the 300 to 450-500 and the cpu.

Looks good to me other than those items.

The last 6 systems I have built I have used Biostar motherboards and I have not had a return yet. I looked at the mb you are looking at and since it does have a pcie slot for a video card,I would do as the other guys said and get a good name brand ps around 650 w anyway.As far as the cpu, my last personal build [my signature] I thought I would try the Phenom 9650. It is a very good cpu [I took it from 2300 mhz to 2550 mhz and it is stable] however I really wish I would have installed an AMD 64x2 6000+. I dont need the Quad cpu and the dual is faster stock at 3100 mhz. I have gathered prices for a friend on a new build complete for $455.00 ,XP pro,dvd burner sata hd,2gb mem,floppy,case,mb,cpu. PM me and I'll tell you where I found the best prices,free shipping. Good luck on your build.
