See what leftover computer you already have

Before you buy a tiny computer, check what leftover computer you already have.

The leftover box already has a name on the sticker. Linux keeps a copy of that name. This note is that name, so you know whether this leftover is an OptiPlex, an EliteDesk, a leftover laptop, or a generic board. The chip name is a different look: see how many workers the leftover box already has. The OS name is see which OS the leftover box is already running. You do not need an N100 this morning because you do not know the leftover model.

Skip until SSH works

If ping fails and SSH hangs, start with is the leftover box still on? If you have never logged in from the couch, that is SSH from the couch. Prefer this look after the leftover box is doing real work, before you shop: start with what you already have. This note assumes you can log in from the couch.

What this is

A look, not a shopping trip. You are reading the leftover box's own computer name, so you know what you already have. You are not buying an N100, an N150, or a Protectli tonight. You are not wiping the leftover because the name is old.

Ask the leftover box its name

SSH in from the couch, then ask:

cat /sys/class/dmi/id/product_name

That one line is the leftover computer name. OptiPlex 7050, EliteDesk 800 G4, or a leftover laptop name is a leftover office box. Keep using it. Do not buy a mini PC because the name is old.

Optional maker line

If you want the maker next to the name:

cat /sys/class/dmi/id/sys_vendor /sys/class/dmi/id/product_name

Two lines. The first is the maker. The second is the leftover computer name. Dell Inc. plus OptiPlex 7050 is enough. Keep this light. Do not install extra tools for this look. Do not read the serial files. Those are private, and they are not this look.

Optional spoken form, if you already used it for the OS:

hostnamectl

Point at Chassis. laptop or desktop tells you leftover laptop versus leftover office box. Hardware Vendor and Hardware Model show up on some leftover boxes, not all. The leftover-box name on the house network is a different line. That name is give the leftover box a name that sticks.

If the name is empty or generic

No /sys/class/dmi/id/product_name usually means this leftover is not a typical Intel or AMD office box. A leftover Pi, some ARM leftovers, and some pretend computers skip that file. To Be Filled By O.E.M. or System Product Name is a generic board leftover. The chip name still helps: see how many workers the leftover box already has. Do not buy a tiny computer because the file is missing, or because the leftover printed a placeholder.

What next

Worker count stays see how many workers the leftover box already has. Total memory size stays see how much memory the leftover box already has. The leftover disk size is see how big the leftover box disk already is. Overflow memory on the leftover disk is see if the leftover box already has extra memory on disk. The VM flag stays see if the leftover box can run a pretend computer. The leftover-first rule stays start with what you already have. The later buy is a tiny computer you can leave on, when the leftover box is actually in the way.

Skip

• Skip if SSH fails. That is is the leftover box still on? or SSH from the couch.
• Skip buying an N100 because you do not know the leftover model, or because the leftover printed an old name.
• Skip shopping from a model string. The leftover box you already have is still the first box.
• Skip reading serial numbers or asset tags. Those are not this look.
• Skip a NAS for this look.
• Skip Proxmox tonight. That is what a VM is, and when you do not need one.
