The Sega Naomi Universal was manufactured in both Japan and the UK.
The dimensions of the Control Panel are 630mm x 127mm. The move strip inlays measure 480mmx70mm.
European models were normally shipped with either Sanwa 29E31S or Nanao MS-2932-S. Both monitors are VGA only monitors, not capable of being used with JAMMA games. It is possible to change the electronics on the 29E31S to make it CGA/EGA/VGA capable, but not the Nanao.
The Naomi Universal can be converted from a standing cabinet to a sitting cabinet by following the Sega Naomi Universal Sitdown Conversion guide.
PSU by Sun (400-5397-1) is very similar to a normal PC ATX power supply. Instead of a receptacle for a power cord, it has 110V AC input through a male 3pin AMP_Universal_Power connector. The PSU cannot operate from 220V AC.
Original fan is a 12V two-wire Yate Loon D80SM-12 80x80x25mm rated 27 CFM, if it's noisy it's a good idea to change it. A nice replacement is the Papst 8412 NGMLE at only 19db, though any 80mm 12V fan should work fine.
