I am looking to build a system primarily for storage purposes at my Home. I have a high end laptop for work, so won't use this much or at all for doing any processing intensive task. Here is what I want to do. A P4 (it will be cheap, and I don't need too much processing), with 1 GB RAM and 2 Hard Disks of 2 TB Each (Internal). The PC will be connected to Internet via Wi-Fi dongle and/or ethernet.
What I want to ask is, if there are any limitations to storage based on processing and RAM. And if yes, at max upto what?
PS: This system will be Storing my Media Collection from my Laptop and other devices, and syncing some of it with online storage. The system is required to run 24x7.
