UPDATE
Well, it's been a few days since I've posted. I have been busy though.
I've been going through all the old computer cases that I've accumulated over the years. Most of them are Dell's and other such proprietary crap.
For the most part, I've just stripped them for the hard drives. You can never have too many hard drives!
I did however manage to find an Asus P5Q Pro Motherboard.

I also cleaned out an older Cooler Master case, and I'm installing the P5Q into that.
I'm debating whether or not I want to use my fancy CPU Cooler on this or save it for a better MB later.
I do have a good Intel cooler, but I need the plastic locking pieces before I can use it.
I've got 3 sets of DDR2 RAM for it, shouldn't be a problem finding a set that is good, (pretty sure it's all good).
As you can see in the photo above, I'm installing a set of OCZ Platinum PC2 8500 RAM.
I'm going to put the Q6600 CPU that came out of my system into it to confirm whether or not it's good.
Of course, I always have a Duo Core chip to fall back on if the Quad Core proves to be faulty.
Just ignore the thermal compound on the CPU - I'm going to clean it properly when I install the cooler. It's just in there so it doesn't get lost, and to protect the socket.
Not too sure how much time I'll have to devote to this project over the next couple of days. I've got the usual month end errands like grocery shopping and such to do. I've also arranged to buy a portable dishwasher off of someone on Craigslist

Taxi driver is going to love me!

Nothing worse than standing at the sink doing dishes by hand when you have a bad back!
I'll let you know what happens when I get this system together in a few days... hopefully.
Thanks all!
