Just as easily, you could build the "budget AMD gamer" and drop the video card.

That motherboard has built in video. The video would be weaker than the
Llano system, but you don't need a lot of video in this case. This is
copied from the Toms site.
Processor AMD Athlon II X3 450 Rana-based 3.2 GHz CPU $78
Motherboard Biostar A880G+ Socket AM3 Motherboard $55
RAM G.Skill Ripjaws X Series 4 GB DDR3-1333 Kit (2 x 2 GB) $30
Graphics Card XFX Radeon HD 6770 1 GB <----- dump this $120
Hard Drive Western Digital Caviar Blue WD5000AAKS 500 GB 7200 RPM Hard Drive $50
Case Rosewill Challenger ATX Mid-Tower $50
Power Supply Corsair Builder CX500 500W 80 PLUS $60
DVD Burner Lite-On iHAS124 24x DVD±RW Drive $19
With this chart, you can see the X3 450 is a fair ways up the chart. So
it's a good purchase. The problem with a bulldozer board (A8-3850) is
the motherboard might be a few dollars more.

Of the AM3 ones that are still in stock, you could go with a 3.4GHz triple core. $85
The thing is, these are likely getting close to discontinued, as Bulldozer (A8) takes over.

Now, to find an AM3 motherboard. This is a microATX for $80, without a lot
of bells and whistles. No USB3 for example. Has a selection of video
connectors for the Northbridge video output.
"ASUS M4A88T-M AM3 AMD 880G HDMI Micro ATX AMD Motherboard" $80

There is at least one 140W processor in the support list, so VCore is probably OK.

4GB of RAM for $29. I selected sticks with heat spreaders, only so they
could be plugged in a bit easier without hurting your fingers. The low profile
sticks are a little harder to insert. If the RAM defaults to 1600, you can
dial it down to 1333 and keep the other timing.
"Kingston HyperX Blu 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)" $29

The BIOS on the motherboard has a VDimm adjustment, and can be dialed to
1.65V. Normal DDR3 is 1.5V. The adjustment thing adds in increments of
0.15V and starts at 1.2 minimum. (1.2, 1.35, 1.5, 1.65 etc).
Hard drive prices are all over the map (due to flooding in the country
they're manufactured). You can probably do better than this. The SATA 6Gb
also supports operation at 3Gb or 1.5Gb/sec.

This is the last case I bought. The door is horrible, so I removed it,
leaving the hinge hanging there. The hinge is spring loaded, and it might
be removable as well, leaving that door to rot in the box. I didn't pull
the hinge, because it wasn't absolutely necessary, but even the hinge
turned out to be a pain in the ass (keep bumping into it).

And this is the power supply I put in it, a 400W. No power factor correction
and 70% efficiency. Also, units like this do *not* come with A.C. power cords.
Buy the cord separate. (At least, I don't see a cord in the picture.)
This one also has a lot of Molex, so pick up a couple Molex to SATA power
adapter cables.
