Just wondering if I can utilize my old PCs to start mining cryptos. But not sure where to start for those old types of equipment. Need advice.
Here is some small information about the equipment I have in my storeroom:
What I'm looking for? Which GPU should I buy for each PC? I mean which one will support with them. Also, you can suggest any CPU mining coin.

1. Quad-core 2.9, Intel G41 mainboard, 8 GB RAM, 1 GB internal graphics
Which GPU best suits this one for mining? (if any)

2. Core 2 Duo, Intel G31 mainboard, 4GB RAM, 1 shared graphics
Which GPU best suits this one for mining? (if any)

3. Core i5-650, H-55 mainboard, 4GB RAM, 1 GB onboard graphics
Which GPU best suits this one for mining? (if any)

Thanks in advance for your valuable time.

If you just want to learn how to mine, sure. You can use any of those CPUs to mine coins. Turn one on, set up a bitcoin wallet, download awesome miner and point it at nicehash and/or mining pool hub. Then start tinkering with it. It'll take years to mine enough to actually get a bitcoin payout, though.

You can probably use most any of that w/ a GPU or two. Depends on how many pcie slots/lanes each has available....but GPU mining most any alg requires very little from the cpu. Really just need enough CPU & RAM to run the OS.

If you ever get to the point where you want to spend a little money and build a proper mining rig? Buy a used MoBo designed for multiple GPUs & mining. It's just less of a PITA.
