ATX cases, build ur own PC

There are basically three types of motherboards. ATX...AT and Baby AT. The case must support the type of board you have so an ATX case is made for an ATX board. ATX has features that the others don't. One of them is that when you shut down the computer it goes off by itself as opposed to AT where you physically press a power button.

The reason the case lists the wattage is because most cases come with the power supply already in them. So the case you refer to has a 235 watt power supply in it. A mid tower  is a medium size case where a mini tower is a shorter one and a full tower is a taller one. The one you cited is about 15 inches high. It makes for more room inside to help increase airflow to keep it cool.

As far as being easier to build your own that is a relative question. It is not easier to build one than to buy one already built, but when you do it yourself you get many more options and choices and the good feeling when all goes right.             Mrbreeze

A "midi" tower is taller than a "mini" tower, but not as tall as a "full" tower.  The taller the tower, the most empty bays you have, for adding internal hard-drives and CD-ROM/DVD/CD-writers.

Most cases also include a 'PSU' (Power Supply Unit), which has been pre-selected to fit into the case; that's just one less detail for you to worry about when assembling your own PC.

OK thanks I didnt realise that the power supply unit comes with the case.  If the case costs about £30 ($48) does that sound right ie with power supply.  Are power supplies that cheap.  Or perhaps its the other way around, power supply comes with case, as metal and plastic case is cheap to make?

I currently have an ATX as the comp. switches itself off when shutdown.  I was annoyed when having purchased it, the case was larger than my old mini tower.  I take it then, there is no way an ATX board can fit into a small mini tower?

Finally nobody answered my bit about jumper settings on new motherboards.  Are they jumperless free so that it makes it impossible to short circuit the board?

I'm planning to build my own computer, so how can I make sure I have every single small part, right down to the USB connector plug?

Some motherboards have jumpers;
some motherboards are jumperless;
very few, if any, are jumperless-free.

Thanks to all.

Anyone know any website in the UK which sell "everything" you need to build a PC.  I would hate to have to find every part myself and then realise I'm still missing a screw or connector.

....and a static free area is where?  Bedroom ok?

I'd go to www.pricewatch.com and see if they promote any companies in the UK.  As far as static free areas go, be sure that you are not on carpet, try to be in a fairly humid area, and wear a static strap connected to an earth ground, such as the ground plug of an electrical outlet.
