John I think you have two different issues intermixed here.

The issue here is making sure your new drive does not require more power than what you are replacing. From what I remember this model has a [http://www.seagate.com/staticfiles/support/disc/manuals/enterprise/Barracuda%20ES/SATA/100424667b.pdf|Seagate ST3500630NS Drive] It needed:

* Temperature (°C max) - 60 (operating) 70 (non-operating)
The second issue is the reliability of the power supply unit in the Time Capsule its self. This is were things get iffy. The first gen units did not hold up well and Apple does not offer parts for it anymore.
Let me add: The WiFi services on the this model was just so so: 802.11n {draft}. Review the following: [http://en.wikipedia.org/wiki/AirPort_Time_Capsule|Wikipedia: AirPort Time Capsule] Newer units had better WiFi throughput.
So doing the upgrade:
* From a HD perspective - Quite doable
* What about the lifespan of the unit - Iffy, no parts from Apple, will need to make your own.
* WiFi Performance - Not bad but not as good as the newer 802.11n units.
