$1K is actually cheaper than the comps sold in this successful KS ca. 2016
https://www.kickstarter.com/projects/multigamesystem/kawaii-cade-japanese-style-bartop-arcade-cabinets. I have a BOM spreadsheet for the countercades I've created and the totals are never less than $600, not including the many hundreds spent on R&D dead-ends. Apprx. $50 reclaimed mon, $25 Sanwa Joystick, $30 Sanwa buttons, $15 power button, $15 select/start buttons, $10 screws, $15 heat-nut inserts, $10 crimp connects, $20 wires, $15 HDMI splitter, $7 x 3 HDMI cables, $10 x 3 panel mounts, $10 speakers, $25 amp, $28 paint/clear coat, $23 spot putty, $50 filament, $130 R Pi5, $80 custom CP and sideart, $21 psu, $7 fan, $8 fan button, $10 JST connectors, $9 USB panel mounts, $10 LEDs, $18 encoder... that's just raw materials off the top of my head and I'm forgetting a bunch of stuff. A prototype countercade takes over 250 hours from CAD to completion. Subsequent builds are about half as expensive in times of time and only slightly less in money but are still not cheap! This is an expensive hobby but you get a lot out of it!
