Requirements for 16/24 WoW Multiboxing accounts

[PonasArnas]

Hey, so today I had this question. If I wanted to multibox with 16/24 accounts on one PC. Fps could be around 15-20ish, graphics as low as possible and no addons. What estimate PC build would I need? I assume I would need lots of RAM, but not sure about other specs, if any of you had this kind of experience or any knowledge, maybe you could advice me (using isboxer)? Thank you in advance.

run one account, take note of system resources it uses, multiply that by x, then account for overhead.
