A home lab, without the jargon
A home lab is just a quiet setup you leave on. You don't need to buy anything to start. Use the old laptop, or a retired office PC from Marketplace. What to skip, and what is worth money later.

Topics
Your first weekend
Install the OS, name it, leave it on. Don't buy anything this weekend.
Getting startedFind it on the house network
The number you type in SSH. Router list or hostname -I. No new router.
Getting startedSSH from the couch
Type commands on it from the laptop. House network only.
Getting startedWhat OS to put on it

When to spend
Start with gear you already have. If an upgrade doesn't fix something you can feel (slow file copies, a dead Wi-Fi corner, a machine that won't stay on), keep the money. Gear you never plug in is a waste.
