It was quite hilarious how that particular build cascaded.
I started out with a Stock re-manufactured Acer Aspire, and then popped in an HD2800 pro so I could play steam games.
Being thoroughly unimpressed with that card, I dumped it for an HD2900 Pro, and then hit around 7k in 3d mark 06. Wanting more speed, and knowing enough to know that the stock Acer OEM board locked me out of overclocking, as well as the fact it did not have a full PCIe x16 2.0 slot, I replaced the board with a 780G Gigabit board, and picked up 4GB of OCZ reaper DDR2 to go with it. Knowing the stock cooler was just about useless for what I wanted to do, I shopped around for the biggest, baddest air cooler at the time, and then did some crude measurements and figured out that I could squeeze in the Core contact freezer 120. I ran that @ around 2.9GHz for a few months, and then replaced the 4200+ with a 5400+ BE when it came out. Lucky for me the old Acer oem stuff covered the cost of the new cpu (who knew that someone would've wanted the crap oem board) and I ran that one a couple hundred of MHz faster until a couple of years of abuse finally took out one of the BE's cores.
I still run the factory Acer IDE DVD burner in my current system, and recently replaced the 400GB WD drive that came with it.
Now I've got the parts from my old system gathering dust for a HTPC build. 😀
