HP Desktops
Sell an HP desktop, EliteDesk or ProDesk
Any HP desktop PC — the black or silver box with the HP badge, whether it stands on the floor, sits slim on the desk, or hides behind the monitor. Working or faulty, one machine or a floor of them.

Which HP is it, and which era
HP has renamed the same machine three times in five years. Almost nobody selling one knows which era theirs is from, and it changes what we are looking at.
Up to G8 the office machines were EliteDesk 800 and ProDesk 600 or 400, with the generation on the end — EliteDesk 800 G6, ProDesk 400 G7 and so on.
At G9 HP dropped “Desk” from the name and put the shape in instead. The same machines became HP Elite Tower, Elite SFF and Elite Mini 800 G9, and HP Pro Tower, Pro SFF and Pro Mini 400 G9. This is also the moment the 600 moved from the Pro tier to the Elite tier, which is why a ProDesk 600 and an Elite 600 G9 are one family and not two.
From 2025 the old names came back with entirely new numbering, as EliteDesk 8 and ProDesk 4 in G1i, G2i and G2a. Very little of this is being resold yet, so if you are reading this you almost certainly have something from the first two eras.
If none of that matches what is printed on yours, do not worry about it — tell us what the case actually says, word for word, and we will place it.
Shapes
Which shape of HP is it — Tower, SFF or Mini
HP builds the same machine in three sizes and they are not worth the same, so the shape is worth reading off the case along with the name.
Tower and Microtower
The tall box that stands on the floor.
HP writes these as TWR and MT. Note that HP's MT is Microtower — Mini Tower is Dell's word for roughly the same size, which is one of several places the two makers' vocabularies do not line up.
Small Form Factor (SFF)
The slim flat box that sits on the desk.
The commonest shape in offices, and the one most likely to be sitting under a monitor. Takes a low-profile graphics card at most, so it is worth a look before assuming there is nothing in it.
Mini
The little one, about a litre, often clipped behind the screen.
HP called this Desktop Mini, or DM, before shortening it to Mini. Micro and MFF are Dell's words for this size and Tiny is Lenovo's, so if the case says one of those rather than Mini you are probably not looking at an HP.
EliteOne and ProOne
The ones where the computer is built into the screen.
HP's business all-in-ones, more recently EliteStudio and ProStudio. An all-in-one is a screen as much as a computer, so it travels like a monitor rather than like a laptop.
Older shapes you may still meet: USDT, HP’s ultra-slim desktop, and CMT, the convertible minitower from the HP Compaq era. Both are still worth asking about.
The rest of the range
Z-series workstations, all-in-ones, and Pavilion and OMEN desktops
HP Z-series desktop workstations — Z2 Mini, Z2 SFF, Z2 Tower, Z4, Z6 and Z8, and before them the Z240, Z440, Z640 and Z840 — were built for engineering and rendering rather than office work, and they hold value considerably longer than an office tower of the same age. Selling a ZBook mobile workstation instead? That is the laptop page.
EliteOne and ProOne all-in-ones, and the EliteStudio and ProStudio machines that followed them, put the computer inside the display. That makes them a screen as much as a machine, which is worth knowing when we talk about how it travels.
Pavilion, Slimline and Envy desktops are the home half of the range. They do not hold value the way the business machines do — that is worth being straight about rather than discovering later — but they are still worth asking about, especially if anything was added to them. HP has since moved these to the Omni names, so a newer machine may say OmniDesk where an older one says Pavilion.
OMEN and Victus desktops are the gaming end, and there the graphics card usually carries most of the figure. Worth writing “OMEN desktop” rather than just “OMEN” when you enquire, because HP puts both names on laptops as well.
Getting it to us
Faulty machines, and how HP desktops travel
A desktop that will not start is worth asking about rather than binning. A failed power supply is routine and cheap, and the rest of the machine is normally untouched — which is a better position than a laptop in the same state. Selling a broken laptop covers the portable equivalent.
Towers and all-in-ones are heavy and awkward, so HP desktops normally go by collection rather than post. That includes the small ones: an Elite Mini would fit in a jiffy bag, but ask us before you send it and we will confirm the route and anything it involves before it is arranged.
Payment is made at the time of collection, once the collector has checked the machine matches what you described. Say on the enquiry if the machine holds data — eligible storage is wiped and a data erasure certificate issued, and anything that cannot be wiped is destroyed rather than passed on. Please do not pull the drive out first; a machine missing its drive is worth less than the same machine with the drive wiped. Data wiping and secure data destruction covers it.
Not an HP after all? Selling an old computer takes it from the shape alone, whatever badge is on the front.
A fleet rather than a machine? IT asset disposal and business collections handle it as one job.
