If you can live without the small form factor case, Outpost.com usually have the Semprom 2800/3000 with full size ECS motherboard combo for $80 - $90.
I just received the Semprom 2800 + ECS MB combo and it's doing great. Straight out it's overclocked from 1.6Ghz to 2.0Ghz no sweat at stock voltage( 1.4V ) and stock heat sink. This is how it boots up, not tweaked from windows so it's robust OC.
AFAIK, the Semprom 2800 has bigger L2 cache than others, 256KB vs 128KB and it overclocks just as well. Others claim having taken this chip to high as 2.6Ghz.
I'm using an old PNY memory module with SPD of 2-3-3-7 at 200Mhz - 512MB.
This PC is my file server/video compressor/file sharer.
