for me, seven, it would be eight, but i switched my single F@H boxen to ECCP when i pulled the P3-700 cpu out and replaced it with a celeron 266@400, with that short time limit F@H has, i will only run it on boxen with fast cpu and SOLID internet connection
i am looking to become a jack of all trades, i want to run at least one home pc on all eleven projects, but right now i only have 8 pc's at home and then use the work farm to move around to projects that are lacking in active participation, kinda like a mini - ars flying squad idea like they do at Arstechnica
