The HP Stream Mini is an entry-level model with a starting price of $180, while the HP Pavilion Mini has more powerful hardware and a starting price of $320.
Both computers fit inside a 5.7″ x 5.7″ 2.1″ case that weighs about 1.5 pounds.
While HP had originally promised that both models would be available by January 14th, it looks like the company missed that deadline. But a little over a week later a high-end HP Pavilion Mini with a Core i3 Haswell processor went on sale for $450 (or $435 with coupon code 15HPDEALNEWS).
This model features Intel HD 4400 graphics, 4GB of RAM, a 1TB SATA hard drive, Gigabit Ethernet, 802.11n WiFi, Bluetooth 4.0, four USB 3.0 ports, an SD card reader, and it comes with a mouse and keyboard.
HP will also offer a $320 model with a Pentium 3558U processor and a 500GB hard drive soon, as well as the $180 HP Stream Mini which has a Celeron 2957U processor, 2GB of RAM, and 32GB of solid state storage.
Each model has HDMI and DisplayPort, allowing you to connect two displays simultaneously.
The Pavilion models ship with Windows 8.1 64-bit software, while the HP Stream Mini runs Windows 8.1 with Bing 64-bit.
Note that while all of these desktops are tiny, they’re not fanless.
