Hi Robin funny enough I have started looking at other small form factor boards.
Known small form factors worthy of a look are:
- microATX min(171 x 171)
- Mini-ITX (170 X 170)
- Epic (EXPRESS) (165 X 115)
- MiniATX (150 X 150)
- ESM (149 x 71)
- Nano-ITX (120 x 120)
- Com Express (125 x 95)
- ESMexpress (125 x 95)
- ETX/XTX (114 x 95)
- Pico-ITX (100 x 72)
- QSeven (70 x 70)
- Mobile-ITX (60 x 60)
- CoreEspress (58 x 65)
I noticed the bigger forms use an Atom where as the smaller usually a via chip-sets. Lots of complaints about the via drivers.
It's another method worth exploring. I still have lots to look at but the pricing of some are outrageous.
