There is a post here
that will probably give you some good build ideas. I would suggest taking a long look at Night Fox's post since he includes an SSD.
Motherboard/CPU: If you're looking to overclock grab an i5 2500k and ASUS P8P67 Pro. If not you can just grab the non "k" version and non "pro" version of the same components.
PDU: Not sure what this is, assuming PSU? check out this thread
for reliable companies and rough wattage calculators.
Also I think you might want to check the graphics performance list
, incase you want something with more oomph than what is suggested in the thread above.
