Case form factor/ size

[dkm]

Just purchased an Abit BH-6 mb, and it won't fit into the standard
ATX case which I have aquired. The dimensions are of the board are 305(12) x 190(7.5) mm (inches). The mouse/kb/ printer ports are on the longest side of the board (near the corner). This is my first attempt at building a PC, so any help is appreciated. What size/style/form factor/power supply do I need? Thanks.

If I remember right the BH6 was full ATX . You'll need a midtower ATX case minimum I would guess. Look for a case with 3or4 5-1/4" expansion slot in the front. Also, at least a 300w power supply.

Umm....thats strange. I've got that same board in a mid-size ATX case and it fits just fine. A bit tight, but it fits.

Also a 250W should be just fine cause thats what I'm using on that board and I've got no probs.

Thanks for the help, but I think I have found the problem. Talked to a tech, and the power supply for the case I have has double power plugs for the mb, which is apparently what the AT form cases use. The Abit mb has the single socket for power, which would indicate an ATX form. Guess I'll have to just get the proper case. Thanks again!

Doh! Thats too bad. :( Hopefully when you do get the correct case you've got no problems with that board. Pretty stable for me. No probs so far with it.

Inductive reasoning -- from the specific to the general -- is not very appropriate in this case. The fact that a 250-watt PS is enough for one system is no reason to assume that it is a good recommendation for others.

The model or type of motherboard is just one of many factors to consider when choosing a power supply, and in fact it's a relatively minor point. The CPU, the video card, and the number of DIMMS, drives and expansion cards are all much more important when making a decision.

A power supply that runs at 50-60% of its maximum output capacity will run cooler and last longer. If it has a fan-monitoring feature, it may also run quieter.
