Closed [US-FL] RX VEGA 56 NANO, RX 5600 XT ITX, or RX 5700 ITX

Planning my Velka 3 build and looking for a correspondingly small GPU. Specifically, these models:
AXRX VEGA 56 NANO 8GBHBM2
AXRX 5600 ITX 6GBD6-2DH
AXRX 5700 ITX 8GBD6-2DH
I can go up to roughly 1.5x MSRP on each, but anything near MSRP would be great. I also would be interested in similarly powered and sized GPU models from Nvidia, but AMD is preferred.
