when it come to collecting arcades games the 3 things you will need is,  space, time, and of course money. space is one of the most important thing i don't know why but when you start collecting this machines you cant really stop it`s nothing like receiving a new game and try to restore it and be part of your game room , time also is a big factor fixing restoring arcade is a lot of time consuming, and of course this all thing is not cheap at all ....
if you don't have the space, time, or don't wan spend to much money , you can build a MAME cabinet , you will just need a computer an empty arcade and basic skill in whirring , after that you will be able to play thousand of games on a single machine.
it`s what my friend ALON did , i help him to build a very cool mame cabinet but i realize something , even a single cabinet can be problematic , it`s not the fault of the money space or time , but one factor i forgot to mention earlier , WOMAN :( 
ALON wife (ANNA banana) couldn't take the fact to have an arcade machine in her house, to big , ugly ect...
my friend birthday approaching i decide to try something why not build him a mini arcade machine?
something really small who will take no space and on the same time look very nice.
after some research i found on ebay an empty countertop poker machine, the price was very good $50 , the machine is register as non working .

after few days this is what i receive, it`s a counter top poker machine , it`s empty only the pcb and power supply are remaining.

it`s made out of wood and steal , most of the wires are there .

i`m going to use the computer ALON use to have in is other machine and also the i-pac

i found a really good 9" monitor on ebay, vga for a very good price
my first challenge was how to install the 9" monitor to the machine ? well after few hours of search the best solution was to strip the all monitor and attach the front plastic cover to the top of the machine , for that i drill 3 holes into the steal and secure the front plastic . after that i reattach the monitor to it and leave the other half strip
after that i install the pc mother board into the machine with the pc power supply ,was really tied but everything went to place.
i rebuild the front of the machine with a piece of ply wood and install a joystick with 3 buttons and rewire everything to the i-pac
i install a new t-modeling and for the decoration i order some checkers decals on e-bay , for the sides i got some really nice video games characters
after 2 weeks of hard work ALON was able to enjoy is new birthday toy , and for the cherry on top of the cake is wife ANNA loved the machine ......
