I want to start building a computer but the only thing i am confused about is the different pc cases, theres so many different types and what motherboards fit into which? i search the forum but couldnt find anything.

also im am going to be using the PC in uni so i would like it to be small, such as the new small form factor pc's that are available but i dnt really mind as long as the tower has 1 drive bay for a dvd rom drive and another for a floppy drive.

You won't get an AT case or components if you're buying new now. They're an old standard, not made for some 5 or 6 years past.

The only comment I would make about cases, is try and manage with a standard size - the mini cases are all well and good, but are a tad "crammed - so makeing cooling more problematical, and upgrading difficult.

With a standard sized tower, you can use any motherboard you want, as there will be space for any size. It also means no buying mistakes over sizes, as almost anything you buy will fit into the case.

what is the actual name for a standard sized tower? mini, midi theres so many names, so dam confusing

Don't worry about what they're called - just look at the sizes - normally around 40-44cms high.

A midi tower is about the same in height as a 17in monitor.

The reason for AT, ATX etc cases revolves around the power supply unit and what voltages are supplied to the motherboard etc.

The mobo's dimensions and fixing facilities within the case are also involved.

See: click here for an explanation of the various form factors.
