HP Elitedesk 800 G2

Released in 2015, the HP EliteDesk 800 G2 represents HP’s business desktop lineup during Intel’s 6th-generation Skylake era. Designed for corporate environments, it prioritized reliability, serviceability, and security. The series featured two primary form factors: the Small Form Factor (SFF) and the ultra-compact Mini (Tiny) model. Despite its age, it remains popular in refurbished markets (~$100–$300 in 2025) due to robust construction and upgrade flexibility. Key innovations included DDR4 memory support, Thunderbolt 3 readiness (via add-on cards), and TPM 2.0 security – positioning it as a cost-effective solution for office productivity, light gaming, and homelab projects .

  • i5-6500 (4C/4T, 3.2–3.6 GHz) – Base configuration

  • i7-6700 (4C/8T, 3.4–4.0 GHz) – High-end option

• Chipset: Q170 (business-grade) with vPro support for remote management

• Graphics: Integrated Intel HD Graphics 530 (P530 for Xeon models) 3.

Connectivity

• Networking: Intel i219-LM Gigabit Ethernet (SFF/Mini)

• USB Ports:

  • SFF: 10× USB (6× USB 3.0, 4× USB 2.0)

  • Mini: 6× USB (4× USB 3.0 Type-A, 1× USB-C, 1× USB 2.0)

• Video Outputs:

  • SFF: DisplayPort 1.2, VGA

  • Mini: DisplayPort, VGA (configurable rear port for serial/DP)

• Wireless: No onboard Wi-Fi; M.2 A/E-key slot for Wi-Fi 6 cards (e.g., Intel AX200) 311.

Power and Cooling

• SFF: 200W 80+ Bronze PSU (proprietary form factor)

• Mini: 65W/90W external power brick

• Cooling: Single blower fan (SFF) / passive CPU heatsink + system fan (Mini)

4. Upgrade Potential and Gaming Viability

SFF Gaming Upgrades

• GPU Compatibility: Low-profile cards drawing ≤75W via PCIe slot:

  • AMD Radeon RX 6400 LP (50W, 4GB GDDR6) – Best value for 1080p medium

  • NVIDIA RTX A2000 (70W, 6–12GB GDDR6) – Professional workstation alternative

• CPU Upgrades: i7-6700 (4C/8T) for multitasking bottlenecks

• Constraints: Proprietary PSU limits GPU power; thermal throttling under sustained loads .

Mini Server/Homelab Use

• Proxmox/ESXi Support: Compatible with Linux hypervisors; ESXi requires custom NIC drivers

• RAM/Storage: 32GB RAM + NVMe SSD ideal for lightweight VM hosting

• Energy Efficiency: 10–35W TDP CPUs (e.g., i5-6500T) for 24/7 operation 11.

Storage Upgrades

• SFF: Triple SATA III (6 Gbps) support for SSD/HDD RAID arrays

• Mini: NVMe speeds up to 3,500 MB/s (vs. SATA’s 550 MB/s) – critical for OS responsiveness

5. Software and Security

• OS Compatibility:

  • Windows 10/8.1: Fully supported

  • Windows 11: Not officially supported (lacks TPM 2.0/8th-gen CPU); manual install possible via ISO

  • Linux: Ubuntu 22.04+ and Proxmox VE run flawlessly 311.

• Security Suite:

  • TPM 2.0 for disk encryption (BitLocker)

  • HP Sure Start Gen2: BIOS attack protection

  • Kensington lock slot (Mini) and chassis intrusion detection (SFF)

6. Real-World Performance and Use Cases

Office Productivity

• Benchmarks: i5-6500 + 8GB RAM handles 50+ Chrome tabs, Office 365, and 1080p conferencing smoothly

• Multi-Display: Supports dual monitors via DP + VGA (SFF) or DP + USB-C dongle (Mini)

Creative Workloads

• Photo Editing: Adequate for Lightroom/Photoshop with 16GB RAM and SSD

• Limitations: Integrated graphics struggle with 4K video timelines

Homelab Server

• Cluster Deployments: Mini units popular for Kubernetes nodes (~$205/unit in 2025)

• Storage Servers: SFF models support NAS setups with 3× 3.5″ HDDs

7. Limitations and Criticisms
