Frequently Asked Questions
EliteDesk 800 G9 vs Elite Mini 800 G9?
Very similar (both enterprise, vPro). EliteDesk often has more standard form factor. Performance nearly identical. Choose based on form factor and pricing.
Can I upgrade to 64GB RAM?
Yes. 2× 32GB DDR5 SO-DIMM (£150–200).
Should I use this for personal work?
Technically yes, but enterprise features (vPro, TPM) wasted. Consumer alternatives (Geekom, Lenovo) better value.
How long supported?
Intel 12th/13th-gen through 2027–2028. HP enterprise support extends further.
Is it worth the premium over consumer mini PCs?
For enterprise IT departments managing fleets: yes (vPro, TPM, manageability). For home/small business: likely overkill.
