Putting fuse box under the hood

I was thinking about doing this:

12-Slot Fuse/Relay Box for (5) 5-Pin Relays, (1) 4-Pin Relays, and (6) ATO/ATC Blade Fuses | PSZACCEPS310H

Mainly to hide relay's. Will have 2 relays for fans (plus fuses) 2 more relays for headlights. Would like to put it inside the wheel well to keep the engine bay a little cleaner.
