Sold 200 Euro, because real price 300 Euro. The buyer will sell it in later more expensive (300 Euro).
If somebody wants to sell something too cheaply, i don't care. It's none of my business. I will not sell it at 2/3 price, I have plenty of time.
I would have been able to sell it below 30 minutes cheaply (200 Euro).
The value of my 1232-50 card will rise and rise, because they never produce a faster card.
I hope you have plenty of time. say, .... about 25 years or so.
That's the time it will take to make this board of yours rare. Since it is still being made and retailed people will spend money on something new and with warranty...
If my choice is to pay you 300 EUR plus shipping VS paying 290 EUR (plus shipping) for something new and with warranty. I'd choose the warranty any day of the week and twice on Sunday....
I have been looking at the pictures available at the ACA 1233 cards. and it seems fairly easy to do a cpu swap and modify it to 50Mhz. It don't look to complex.
But considering the aca's are still being made and retailed new, You are never going to get back your investment in time to do the work, and that is just being honest with you. At least not as long as they are in stores. nothing wrong with your work.
But the aca's are still being made.... If i were in your shoes, id hamster these board like a mad hatter, modify and wait patiently till they are rare before selling them. then you will most likely get your money back....
