Requirements,
-High-end PC (Intel i7, 64-bit (Windows 7 with full updates), 16GB RAM or more)
-170GB+! You should ready your HDD (SSD recommended) capacity for that big amount of files (Blocks)
-Internet speed more than 50Mbps
-Internet Router setup (UPNP must be on, no firewall filters, no IP filters) for sync on peers
-Anti-virus, you should exclude Bitcoin on scan monitoring
-Encrypt your wallet, don't put any of your informations when making a passwords, some hackers lurking your identity, bitcoin address, etc.
-You should backup "wallet.dat" to your cold storage (USB, Memory card, Disc (Not recommended if not proper used))
-PC Maintenance (CCleaner, etc...)
When you leave your PC/Laptop opened with bitcoin opened, you should monitor it using TeamViewer (Remote PC by using Smartphones).
You have posted here a whole bunch of misconception, I hope newbies won't read it and think that it's all true.
There's absolutely no need for i7 and 16 GB RAM, Bitcoin Core takes only 300 MB RAM on average.
You absolutely don't need SSD, any HDD would work. Disc space is pretty cheap nowadays.
A few Mbps is enough.
You don't need to install any encryption software, it's all done by your wallet when you are setting up a password.
Cold storage is entirely different thing, don't mix it up with backups.
Monitoring your PC with TeamViewer or whatever is useless and paranoid, if your security has been breached, your coins will be gone forever in a seconds.
