Resources gained from destroyed enemy

[Fyron]

You need some storage facilities so that you can finance retrofits later on. But not too many. As SJ said, it is better to spend the resources than to store them. But, you will want a few of each storage facility.

I found resource storage facilities useful later in the game for when disasters happen, such as enemy wiping out a couple of mineral planets and causing riots on others.
Nothing worse than fending off an attack with ships dying because you can no longer afford the maintenance.

One other time you'll need a lot of storage is when retrofitting an entire fleet which has been out on mission long enough for weapons/sensor/ECM tech to surpass it. Of course, you could just build tons of new ships and keep sending the old fleet out until it dies. It's not nice, but, hey, who ever won a PBW game by being nice to their people?

You shouldn't have been running your maintenance costs that high, I'd say.
Once your maintenance costs are within a system or two worth of your production, you need to start mothballing all of the new ships you build (reserves) and retire some old ships, or switch over to producing maintenance free units such as fighters.

If you lose a system, it would at worst cause some spaceyards to halt, rather than losing ships.

Or, you should have lots of storage for when I use Intel on you, and take your resources. The more you have, the more I have! LOL. Ask Fyron.

That sounds like the Beloch(Raiders of the Lost Ark) thing to say. As you can see Dr. Jones, there is nothing that you can acquire that I can not take away.
