2005 Sony VAIO VGN-FS742/W running Windows XP Home Edition SP3
This was an eBay purchase for $10.00 (alongside with $15.45 shipping and some tax), I also bought a new screen for this laptop since the old one was broken (it costed me $19.49 with $9.88 shipping and tax). Other than that, this laptop is HORRENDOUSLY SLOW.
Specs:
Intel Pentium M
Intel 915GM Express Chipset
512MB RAM

Windows XP Home Edition SP3
