I bought this months ago, but amazon showed it in my history and I had not written a review for a product(s) I like and use daily. But as a 30 year IT person, I often have needs to find cheap PCs either for clients or myself at home.Earlier this year I was in the market for a miniPC, as I wanted to use it as a server for my home network (running linux). Its me, so I didn't want to spend a ton of money, but wanted something decent, that I could upgrade. I'm familiar with this product line, as these are business grade computers, so I've used this specific model at companies (when these were new). In short, HP G-series PCs are pretty reliable, and last longer than their home ones. So no surprise they are for sale as refurbished on here.I was comparing a Dell of similar spec to this one, but this one just won out for price point for what I was getting. I liked them so much, I bought two of them. One for the server, and one to use as spare testing Windows machine that didn't take up a ton of space (and wasn't a laptop).Full Disclosure, I added a 500GB SSD NVMe M.2 drive as the boot drive, so your results may vary in terms of speed. But I will say, it was speedy with the stock drive that came with it (see below)Here's what I liked..- First off, who it came from. I was pleasantly surprised that the Amazon Certified Reseller that this came from (as the box said) is a company I know from my IT experience for decades. While they are a business2business company, many HP (and Dell) PCs I bought over the years, came from this company. So I know they know what they are doing. However, I can't say yours will come from this place, but have hopes that others are as high calibre as this one since they would be Amazon-certified also.- This thing is small, its no bigger than a standard mouse pad.- It's very clean, it almost looked new. No dents, scratches, or dings. The inside was spotless and the CPU had been remounted with fresh paste!- Its powerful. I've done some hard video encoding and testing, and it just purrs along, and this was still with the included 500GB drive!- It's quiet, unless I'm chewing the processor up with something the fans spin up. But even then it is not as loud as my desktop workstation (an HP also!).- It's an energy sipper. I connected a power meter to it for a month, it used so little power (vs my desktop)- Processor speed is pretty speedy and windows preinstall is pretty zippy on it- This model has 16GB of ram which is plenty of ram these days for most applications- Two drive support. This can take 2 drives, a 2.5" SATA drive & a NVMe M.2 2280 drive (just add a screw!)- Plenty of USB 3.0 , 2 USB Type A (flat plug) and 1 USB-C in the front and 4 USB Type A ports in the back- 2 Displayport ports for dual monitor support and a VGA port- Onboard 10/100 ethernet & audio- This specific renewed model comes with a Windows 10 Pro license! (some do not!)- If you're security minded, this does come with TMP 1.0 and other UEFI related security tools.- Since this is an HP Business PC, spare parts and support are easy to find and locate. Everything is HP standard, well tested, and made for years of reliability.Here's what I thought was "meh"- Because its tiny, the power supply is a brick on a cord. Not a big deal and the cord from the brick to the PC is long, but the brick itself has to be put somewhere vs a straight cord.- This model does not come with WiFi or the antenna kit. The MiniPCIe slot exists though so Wifi can be added later and it's not a show stopper for me as these will be hard wired.Here's what I didn't like..None. I do not have any huge things I do not like about this product, other than my meh. I'm extremely pleased with this product!Overall, as stated above, I'm extremely pleased with this product. Add a NVMe M.2 drive as your boot drive and you will be screaming for a low low price.
