Computer prices get lower and lower every day, but you'd be hard pressed to find many complete desktop PCs for under £150. Today, though, we've found just that: an IBM desktop computer, with screen, for £149.

This ThinkCenter M51 has a 3.2GHz Pentium 4 Processor, 512MB of memory and a DVD drive. A copy of Windows XP Professional is installed. As you might have guessed from the price these systems aren't brand new - we strongly suspect the previous owner will have been a company that has just upgraded its network of computers. Still, at this price they're something of a bargain. Click the jump for details.
