MIG-31

As shown in our recent Entry-level Buyers' Guide, you can now build a decent entry-level PC for around $500 - including an LCD monitor and the Vista Home Premium OS. If you already have a monitor and OS, or use one of the free operating systems like Ubunti or another Linux variant, you can get your desktop system cost down to about $300. We don't recall a time when so much power was available in the computer industry for so little money.
