I've been hanging out at the group buy forum quite a lot lately, and seems like aluminium custom case is the new trend these days.
Poker $99 / Pure $99 / Race $129 Custom Aluminium Case:

http://geekhack.org/index.php?topic=34606.0So I wonder when they'll make aluminium case for HHKB? I can see a lot of people will buy it if the price is right. Though at the same time you just might have the most expensive keyboard ever.
Let's just assume it's $200 (Mid point between the two choices listed above). You're looking at HHKB $300 + casing $200 + custom color keycaps $100 = $600.
I list the keycaps because if you're gone that far you probably won't use stock keycaps.
Personally I don't own an HHKB but I figure it's fun to think about also this theory doesn't look too far fetched
