Psystar quality??

hi guys

i am considering buying a computer or building a computer in a month or two.

i am 100% sure that i want to build a desktop computer

i am debating between building my own computer or buying a psystar computer.

the mac osx operating system on psystar interests me and their prices do not seem as crazy

i have no experience at all about building computers, i want a computer that will last me around 5 years with quality. i believe that building my own computer will give me a quality computer for about 5 years but i do not want to mess up anything by building my own.

do you guys have any reccomendations about psystar in general? any experiences or friends experiences? their open7 and openpro is what i am interested in.

thanks a lot, have a great summer!(if your summer started already that is ^^)
