something using the mini-itx formfactor. nano-itx is still pretty non-existant. They're 17x17cm and 12x12cm respectively.
Like firehed says, ITX and Mini-ITX, if you want standard PentiumIII and up quality CPUs. If smaller CPUs are okay, then 486's are avaliable as small as a credit card (2"x3"). Likewise, the ARM processors (up to 266MHz) come in may flawors and sizes. I have seen these as small as 40-pin microcontrollers - no built-in VGA controllers here though. Hitachi also makes a CPU (up to 1GHz), that is mainly used in palm-top gadgets. I have not seen these as single board computers, but I am sure they are available.
thanks for all the info, but im looking for the smallest moherboard that can be used for a fairly powerful gaming computer. but i will look into the ITX and Mini-ITX's. so if anyone has any other ideas plz tell me
For a gaming PC, have a look at mATX boards - they're the only ones that have the big-hitters of CPU's (AMD/Intel) available: ITX mobo's have slower processors.
There is a Mini-itx board that has the capacity for a 3.6 Ghz Prescott and a PCI Express X16 graphics card; you should be able to build a rather miniscule PC around that
i have looked on mini-itx.com and i cant find that board, can you give me a link or somthing? for the rest of you this is for my new gaming computer that i will be building (Hopfuly high proformence). the meserments for the case are 6in wide and 14-15in tall (the meserments can be changed). if ther is any other info that would be helpful, thanks.
This seems to be the procuding company http://www.tcommate.com.tw/ Model LV-672 seems to be the one. Shop option here They also have cheaper options
