I've installed a custom desktop in my room specially designed for this (low table, inclined TV...). I'll post photos when everything is installed. Some may say it's nonsense to spend so much money only for enjoying MAME, but who cares? I'll also have a Dreamcast plugged with a SCART switch, for modern games. I'm so eager to have my new computer! I'm waiting for the CPU, motherboard and RAM to arrive on Monday. These are the parts of my Arcade Desktop:
