5005 vs. 5005X?

I’ve had my 5005 for over a year now, patched to eliminate the copy protection, region free and 3 hour recording. Recently a friend asked for a recomendation, and while looking, I discovered that the retailers are now selling 5005X models.

Anyone know what the difference is? Just the drive? Will the ILO patched firmware still work?

I purchased the 5005x from Newegg a week ago and it was defective out of the box. The display read 'Hello" and thats as far as it would go.
No other functions worked. Sent it back to Newegg for replacement.
Hope the next one works.
