50GB PSP HDD(Not rumor and not internal)
Take an old internal HDD, and mount it on a USB-OTG HDD enclosure.
That HDD can be used via iR Shell, and since the internal drive is just lying around, and the OTG enclosure only costs $25, isn't that a steal?
Are there any Cons to my idea besides lugging around an HDD when I want to play ISO/CSO & PSX eboots?
