This Is a 2001 Dell Optiplex GX 150
With a Pentium 3 CPU Running Windows 2000.
I Got this PC from a Junk Store For 300 Thai Bath.
It Didn't Boot when i first get this PC.
But It Actually Boot without any repair. But the harddrive is dead.
And I Install Windows 2000 SP4 Because It orginal OS is Windows 2000.
Anyways Have a Nice day.
