To me these have no value. I wouldn't bother unless they are very cheap, matching the price of more common hardware, like the 2.8-3.2GHz Prescott for the CPU and PCI-e HD4600 series for the graphics card.
Pentium 4 just didn't scale all that well. EE is more of a collectors' item rather than anything useful. You can reasonably beat it with Something like a Dual Core E2220 on stock clocks and this DC is a fairly good over clocker and generally nearly free of actually free.
As for the graphics card, these late AGP cards with adapter chips are the worst of both worlds. Have issues with compatibility for legacy stuff which makes them unable to run some games and slower than genuine AGP cards in some others, and the performance increase is pointless since you are already well above 60fps in the rest unless the game is locked, meanwhile they also lose performance compared to their PCI-e counterparts.
So 5-15 $ each.
