Understood Ryszard. And I understand the "gotta replace everything" issue. OTOH if you NewEgg, a modern MB, processor and memory could be had for as little as $210. I use the AMD-790GX with the built-in graphics (I don't game).

MB: $90

Two gigs of RAM: $28

A triple core with fan: $77

Everything else in your system could likely be used. This is a very usable system if you are not trying to build a gaming system. I use thatBiostar MB and it is nice, though it has no MOSFET cooler. I use one of the first 4 core AMD chips (slightly lower clock speed IIRC), works fine. And I use that memory except 2 gigs / stick (slightly more expensive but more memory). I run SQL Servers on that hardware. Cheap and gets the job done.

Go with the Gigabyte MB if you want to OC:

$120

With either MB you now have an upgrade path to the new Phenom II quad core at a later date if you find you need it.

As you know building your own has the advantage of lower cost and upgrades down the road, though to be honest a low end DELL is a mighty powerful machine.
