upgrade Airtport extreme to time capsule?

Asked & Answered here: Converting new Airport Extreme to Time Capsule

Possible, but it is a very bad idea because it is actually more expensive to buy separate parts to make a time capsule than just buy one. You also have to add quite a lot of small components on the logic board of the base station and modify the firmware.

"Install a WD portable HD 1T wire to USB port

works well for Time machine. or a NAS.

Remember not to us the external USB if you install the HD internal."

"Dan you are correct is speed limits on USB 2.0. Limited by USB port all I did was simply installed USB drive inside over external. I also recommend the Time capsule over the extreme

It is possible with the new Extreme to install a pair of USB drives and still be able to use the USB port for external devices

From my box of parts. Only for advanced user Mods

One laptop power supply removed the plastic case $10.00One Buck unit to supply power to drives $3.50 12vx5v @ 5ampOne powered USB hub $4.50 4 portTwo WD USB portable drives 1T each used value $50.00Lift the two center pins on USB port on the Extreme hard wire the two center pins of Extreme USB to one of the USB ports of Hub not the primaryPrimary pins from hub back to the motherboard of extreme two center pins only. Note the primary pins of hub normally be plugged into USB port now hard wired to Extreme motherboard where USB pins were lifted observe polarity of both center pinsWhen finished two hard drives 2.5 inside the extreme powered separately from the bucklifting the two center pins on the usb port and routing back though the USB hub allows for external devices to be attached to external USB port of the Extreme .Not knowing of a software Raid that will work ?

Note unless you have extra parts it is not cost effective .and not recommended for average user

The power pac i used is rated at 3 amp.old 12v IBM was small enough Not knowing the power rated of Extreme USB port assuming rated for only one device.

Doing any mod voids the warrant

The previous Airport Extreme is limited by space only one HD is possible by a small mod to heat sink for clearance.

Adding network storage is always welcome to home network.

Thank you Dan for the tactical input, sad the extreme only has USB 2.0"

"So I just signed up to answer this topic and ask more :

I have an old 2tb airport time capsule flat one and the new airport express. I was thinking if I can move the harddrive to the new one or link them to use new airport extreme as WIFI station and the other one only storage.

Heard about another thing using the time capsule only as a desktop Hard drive but not sure what to do.

Let me know guys worth to try or not.

Thanks"
