It's actually surprised me to discover that many of the "big computer hardware" companies in the west have somewhat low ratings compared to what I had expected, so maybe this isn't quite as big of a deal as I thought.

• Seagate is currently Ba2 (Moody's) / BB (S&P's) / BB+ (Fitch)
• Corsair was BB- (S&P's) about a year ago
• Western Digital is BB+ (Fitch)

Nvidia's and AMD's respective credit ratings look higher (though I'm having trouble immediately finding recent numbers), but they're also "hot" right now so probably aren't a good comparison.
