How to buy and sell PC hardware?

Last time I bought a PC which was a month ago I destroyed the motherboard after trying to extend the power cable (>>6520). It came with 2 monitors (one had a scratch in the plastic), 4GB RAM (advertised as 8GB but got scammed), 300GB HDD and original mouse/keyboard for 70$. I cycled about 30 miles because I thought it was a good buy but ended up with regret. I sold the scratched 21" 1680x1050 monitor with VGA and power cable and a 250GB SSD with data cable for 37$ today because the guy didn't have more money on him and I didn't want to let him go home empty-handed. In both situations I wasted a lot of money and time and was wondering how I could get better at selling and buying hardware. Last time I searched for a Thinkpad x220 it was 200$, used and had only 4GB of RAM. I tried bidding 100$ but the vendor immediately started acting like an asshole. Where do you find cheap hardware lainon?

I still have one more SSD that I can sell for 30$. Since I use Linux booting speed doesn't really make that much of a difference so I was wondering I should bite the bullet, sell it and buy something else.

>>6591 Shit I'll buy that

>>7657 This. Had a guy approach me with an used W530 and a t440. The W530 had some spots on the display and lots of fan noise. The t440 had a defective touchpad. I offered him 70 eurobucks for both, which he was so happy about that he paid for shipping. I replaced the touchpad for one on ali (10 bucks) and cleaned the fan on the 530. Sold the t440 for 185 bucks and kept the other one for myself. Bottom line. I wouldn't try to make money off used hardware, the earnings marge for labor is much higher. That is if you don't have some legit business contacts. Buying used laptops off companies in bulk and refurbishing them, for example.

>>6590 I believe part of it is being patient, and being open to buy something different than you wanted initially. If you go on the market to buy a X220 in two days it will be much harder to find good deal than going in for a modernish thinkpad with half a year to spare. Most of my great deals had also a great degree of risk: keyboard doesn't work may be a defective keyboard or a defective motherboard, I took the deal, bought a replacement keyboard from China, and it worked just fine. Could also be that I would have to buy a new motherboard, making it a very bad deal. I think most of the great deals are people investing quite a long time searching for it, or repairing it, and the invested time doesn't show on the price they paid, but is a cost after all.
