The poor man’s all-in-one PC costs $380 including a 20″ wide-screen LCD. Image shows an older 19″ LCD with a crude mock-up attached to the back. The entire computer including the LCD takes 58W in idle and 64W at peak CPU operation. The PC itself consumes 30W idle and 36W CPU peak. The CPU is a 1.33 GHz Celeron 215 processor based on the “Yonah” Core Microarchitecture with the equivalent performance if a Pentium 4 2.2 GHz. See George Ou’s blog for more details.
This is the back of the poor man’s all-in-one PC. The mock-up does not have sides or top to hold everything in but it’s good enough to boot the computer. The motherboard and CPU is a D201GLY which costs $70 at Fry’s Electronics. The power supply is an “80 Plus” 1U PSU from Sparkle Power Inc. that costs $50.
This is a profile view. It’s messy right now but it wouldn’t be with sides and top. The entire thing measures 80mm tall (3.15″) so it will not stick out too far from the back when completed.
Two screws 100mm apart are used to bolt the computer to the VESA mount.
Here’s a schematic of the VESA mount PC with sides, top, and bottom. The sides are half-inch thick MDF wood. The top and bottom are quarter-inch thick hardboard. The cost for the wood material is almost negligible since it was around $7 for a 2×4 foot panel. Check back with George Ou’s Real World IT blog for an updated schematic with higher resolution and dimension labels.
