First of all, is the motorcycle on a 12v power system? If it's not, then you're going to have some issues to work out, namely upgrading the bike to 12v. If it's already 12v, then keep reading.Originally Posted by XS400
M1-ATX probably wouldn't be enough power. Consider an Opus 120w AT LEAST.
Personally, I don't like PC-Chips brand hardware. They are budget components with a budget price and budget quality.
You might consider a 2.5" laptop hard drive to save power and space. Yeah, they are lower capacities.
There's no mention of an optical drive. Not a necessary component except at installation time. You can also use a USB optical drive for when you need to read a CD (not while riding, of course!)
I believe the PSOne LCD requires TV-out. You haven't listed anything that will provide a composite video signal. You can use a scan converter, but the display from those tend to look like crap AT BEST.
