I wanted to share my recent build with Hyperspin frontend. I bought a used Dynamo Showcase HS-15 cabinet with a 34" monitor, marquee and a Tsumo Mega Kit in it. The monitor needed some adjustment but it was working, it probably still could use a cap kit. The cabinet included a Ultracade VGA converter and 2.5mm audio amplifier which made hooking up the PC easy.
The control panel I ordered a kit from Monster Arcades (I know, I took the easy way out). It came with two Minipac encoders.
I got the control panel overlay, cabinet decals and marquee from Game On Grafix.
For the PC I bought a used Dell Optiplex 7010 small form factor w/ Core i5 3470, 8gb ram. I added a Nvidia Gt730 (because I needed analog output), and a 2tb SSHD.
