Addonics offers external Blu-ray/HDDVD combo PC drive

Quoted from engadgethd.com:

Combo drives made specifically with computers in mind aren't unheard of or anything, but they're still a long ways from being a dime a dozen, so we figured it was worth the time to check out Addonics' latest. This peace maker plays back HD DVD, Blu-ray, DVD and CD, but it will only burn to the latter two; also, it's available with eSATA or eSATA / USB 2.0 interfaces, and it should play nice with Windows, OS X and Linux-based rigs. If you're wondering about speed, it can reportedly toast CD-Rs at 48x, CD-RWx at 32x, DVD±R at 16x, DVD±RW at 8x and DVD±R DL at 2.4x. Both of these suckas are available now for $409 / $429 depending on your choice of interface, and trust us, you never know when having something like this around will totally save the night.

It's nothing more than an LG GGC-H20N in an external case. Expensive case too.. considering they're charging $109-$129 more than the GGC-H20N alone.
