Inside the bottom tray you have two cutouts in order to put two 2.5" HDDs/SSDs in

I’ve had the same question when I wanted to seperate my homelab network from my normal network that is also used by my girlfriend.

I tested a MikroTik router from a friend, but it was too deep for me. Ubiquity was too expensive since I was on a budget, so I got a TP-Link Omada Router and PoE Switch, which has a more user friendly UI than MikroTik. Maybe not as nice as Ubiquity but good enough for my needs and some more features than my ISP router.

Around 100 Watts for

• NAS with 4x3.5" HDD,
• Minisforum HM90 for Proxmox with 2x2.5" HDDs,
• 16 Port TP Link PoE Switch,
• TP Link router
• 2x Raspberry Pi 4b

But everything with gigabit speed. Doesnt need more at home
