I'm pretty happy with the result.
Materials:
IKEA Ramvik coffee table (OOS now, found this one for $70 on Craigslist)
Dark Tint glass from OneDayGlass.com (pricey but worth it...around $150 after shipping)
Pi3 and 2 SNES USB controllers (plus 16MB SD card, 2 heatsinks, cover for PI) $88
8 2" I beam zinc pieces from Homedepot for supporting the monitor ($7)
Monitor (ASUS IPS 24") $95
Power strip and HDMI cord ($15)
TOTAL: $425
I didn't do the best job initially at cutting the rectangle hole so I needed to use woodfiller, black paint and foam padding, but this isn't needed if you do a good job initially.
