Worst system (That I technically haven't finished building yet, still waiting on replacement parts) was a 20 dollar computer I bought at a thrift store. It doesn't boot, I think the power supply is bad, it has no memory and I put a Geforce 2 MX in it, mainly just to store the thing. I think it has some old 32-bit Athlon in it. 60 gig HDD I think.
