how far does it get in the boot sequence?
what screens do you see?
any noise?
I'd suggest checking your ventilation. (e.g. Vacuum out the fluff.)
I recently set up a Toshiba, which would overheat at the drop of a hat. (The processor has an auto shutdown feature, to protect itself from overheating.)
If it's not the ventilation, has the heatsink become dislodged?

The LCD never displays anything, don't seem to get any output from an external monitor either.  After pushing the power button it will light up, the CPU fan spins, then the fan shuts off but the power light stays on.
Are you getting any beeping?
No beeping

I've tried to power on while completely stripped (no cd drive, HD, etc) to no avail.  

I did replace the motherboard and cpu - however I bought the mobo/cpu from and ebay seller and although the item is "guarenteed working," I'm not overly confident.
If you're in time, I'd send it back for a refund. But do check the Toshiba warranty. I have had some success (LCD screen, HP SFF PC and other stuff) bought cheap from eBay but fixed/replaced under warranty.
Forced accept.
