''Theres reference for mother boards that do this that you can turn the uncached memory into very high speed swap space. This means that as long as your working set is inside your cachable memory then your computer is very very fast. Anyone know if you can convince Linux to use swap in preference to disk I/O? (ie: swap out disk cache onto a faster medium such as this 'high' memory?) -- PerryLorier''
! Power Supply
If you want to blow up your power supply unit, simply forget to plug the connector into your motherboard after changing it, then plug the power into the wall. (This was a 230W Hyena brand [PSU] by the way). Update - it appears a capacitor blew its cover right off. See [pretty picture|http://www.wlug.org.nz/archive/images/psu.jpg?] Update2: it appeared to have damaged the [IDE] [HDD] as well! Moral of the story - don't buy Hyena brand power supplies.

+These may use [AC] (as opposed to [DC]) power supplies - some other devices don't like this :)
