Update: You may have noticed acidmods.com is currently inaccessible. My good friend CyberPyrot says it’s only temporary and they’ll be back online sooner rather than later.

My only question was, do you still have access to the UMD drive? That was quickly answered and sadly you don’t. So if you’re willing to sacrifice that, then you may add 30GB+ of storage — internally! Otherwise you can rig a similar setup externally with an iPod. Yup, an iPod. Tutorial coming soon…

Nice mod, PVP. And I should also give props to CyberPyrot for his feature in February’s issue of Official PlayStation Magazine.
