Hi again guys

I asked this in another post of mine but because the post was originally about something else, slightly, no one has answered me and that post probably ran its course.

So, I was thinking of selling my machine. On the day I was taking pictures, I found it didn't work. After listing on here I think, and on ebay, being as honest as I can, I had no takers. Alas.

So I decide to see what was wrong with, knowing full well it's the tower and after some messing around with the pc last week, it turns out, I believe, to be the motherboard. I've removed the hard drive, which had mach 3 and vista on it, and the serial port pci card, and slung the thing out the front, to go to the tip.

So, as I'm genuinely confused as to what to do with it, because I have a shed load of things going in my life and in my head right now, I'm asking opinions as to whether I should get a cheap 2nd hand laptop, an rs232 serial/usb adaptor (any good?), ask someone to help me with a copy of mach (or similar) and parameter setting up to get it going how it used to.. Or, sell it as is, with the tools/collets/aluminum I have, so someone can plug it to their pc, give it a few clicks and be done with it.

Give me your suggestions, greatly apprec'd.

Thanks in advance
