Using a sharp knife and following the bone, remove the breasts from the chicken carcass. Discard skin and set breasts aside. Remove legs from chicken and set aside. Using a heavy knife or cleaver, roughly chop the body into fine pieces. Transfer the chicken body and legs to a large saucepan. Add ham, ginger, garlic, lemongrass, cilantro stems, mint stems, and scallion whites. Cover with water and bring to a simmer over high heat. Reduce to low and simmer, skimming scum from surface and topping up with hot water as necessary, until rich and flavorful, about 45 minutes total. Add chicken breasts to pot for last 10 minutes of cooking.

Strain broth through a fine mesh strainer into a 2 quart liquid measuring cup. Remove cooked chicken legs and breasts to a plate and set aside. Discard remaining solids. Add enough hot water to broth to equal two quarts. Rinse pot and return broth to it. Add onion, carrots, cabbage, and Thai chilis and bring to a simmer. Cook until vegetables are tender, about 15 minutes longer, adding noodles in for last 5 minutes of cooking time (or according to package directions).
