I'm typing this and probably breaking the windows xp min. specs.
Intel Celeron 433MHz Socket 370
Mainboard is an i440BX chipset
192MB of RAM

8GB HDD
90W PSU
CD-ROM
Pretty much running 75-100% CPU usage lol. Turning this into a linux box! Just bought a new NIC and USB 2.0 Card.
EDIT: OMG. The min. req. for XP are like <300MHz for the CPU and 64MB for RAM. I'm having trouble running it on THIS!
