asus p4pe with lan and audio
crucial 256 mb pc2700
64mb radeon 9100
52x liteon cdrw

also what is a good cheap case for this setup...I am looking for a case with no more than like 3 5.25 external bays...

hoping to keep the ps and case under $75

350W fortron from newegg would be a good choice

Would the Antec SLK1600 with Antec 300w smart power be a good choice?

Hmmm...never heard of fortron before...anyone else have experience with them?

slk1600 w antec 300W would be an excellent choice
fortron is a very reliable PSU manufactuer

Antec 300w will be just fine for you.
