Well, just look at it as a step forward! 
Maybe it's not the PC you'd like to have, but you can build toward that in the future.
One thing you could try is what I did a few years back. Pick up separate pieces, and stock them in a cabinet until you have enough parts to build the machine with. I did that for about four months. It was driving me batty for a while, knowing I had all those parts for a much more modern machine, but couldn't actually use them until I had enough to make the thing run. But still, when I finally had enough parts, it was a joy to assemble and configure.

Those who fear the darkness have never seen what the light can do.
