If you think none of those are good deals her is what I looking for a refurbished 650mhz to 1ghz 30gb min 128ram min decent video card decent sound card usb & network card for $175 or less.
You can pick up a new box for under $200, I guess... m/b $50, with gfx, LAN, USB, and sound onboard, 256mb RAM $40, processor $40, keyboard & mouse $10. Case & PSU $40. The only extra cost will be the moniter, and you can pick crap ones up really cheap. A 17" CRT shouldn't cost too much either.
Generally refurbished computers are crap value for money, unless you get a decent moniter with it. New boxes cost next to nothing, I was overpricing a bit. Asking for a "decent" video and sound card is asking a bit much for $175 for the entire system though. I guess it depends how you define decent though :P.
