[CentOS] Install to internal USB?

Saw a trick today, wondering if anybody else had done/tried this? Assume 
you have a 1U rackmount with 4 front-accessed drive bays, and you want 
all four bays for a 4-disk RAID5 storage.

The idea is to use an internal USB adapter and a couple of bigger USB 
thumb drives to install to, RAID 1 style, freeing up all your external 
drive bays. At first, I didn't think that a thumb drive would hold 
enough for the O/S, but in actual production use for a file server with 
14 TB of redundant storage, the OS actually uses less than 6 GB!

Here's the internal USB adapter specifically mentioned:

I'd be concerned about getting a higher quality drive than the $10 
givaways at Staples; Anybody here ever tried this?
