2 older/lower powered gpus needed

Look over your shelves and see if you can help me. I have 2 slots to fill on 2 different machines. No extra power connections preferred, but 1x6 pin is okay for the second machine. Both gpus must be capable of Opencl 1.2

First is a SFF HP with no extra power available. I'd prefer low profile, but I can make a non-low profile work. Looking for something like a 750ti or a gt1030 or even a gtx 1050.

Second, a Dell T5500, it has one 6 pin available, but the card must be relatively short.

Let me know if you have something you're not using and I'll see if I can put it back to work. I'll pay you a fair price or work it off in crunching, your choice.
