When you hear “thin client,” you probably picture a tiny, low-power box that just RDPs into something else. The HP T740 is not that. I picked mine up for about $61 (around $80 after tax/shipping), and it’s rocking a Ryzen-based embedded V1756B with Vega 8 graphics, upgradeable DDR4 SODIMMs, dual M.2 (one NVMe Gen3x4 + one SATA), an M.2 E-key slot that actually does PCIe, and—my favorite weird part—a PCIe Gen3x8 slot for low-profile cards. In this video I crack it open (tool-less, which is honestly nice), deal with the annoying HP NVMe clip thingies, reset a BIOS password, and run benchmarks and power tests. Performance is surprisingly solid for the money, but efficiency is rough: I saw ~18W idle in Windows, and even after Proxmox tweaks and running headless I only got it down to ~11–12W. I also tried real homelab workloads: Proxmox, a Home Assistant VM, Jellyfin in an LXC (AMD transcoding was pretty “meh” at ~30fps 4K->1080p and HDR tone mapping didn’t behave), plus some PCIe experiments like 10Gb SFP+ passthrough. The takeaway: it’s an oddball. I wouldn’t buy it as a “cheap low power mini PC,” but if you need four DisplayPorts or you want a small box with a real PCIe slot to tinker with, it’s pretty freaking cool.
