I ran a slave computer, a few years ago, using a 5 x 5 Inch ACER 386-33 embedded PC board. No problems ever with it!!
So, as Gateway owns AMIGA then this must mean that ACER now owns AMIGA??!!
We have a GATEWAY P4 in the house elsewhere and it runs fine. Very easy to work on and fit cards, memeory, etc., unlike some brands which require serious screw driver, swearing and the removal of the power supply to fit extra memory.
The only other manufacturer I've come across, other than GATEWAY, that has a quick strip down design is NCR witha similar single knurled bolt, just like GATEWAY.
