MSI designed the new Hetris H61 Ultra, a 10 liter commercial barebones desktop for the European market. Measuring 330 x 94 x 320 mm, its chassis houses an Intel H61 chipset-based socket LGA1155 motherboard, which supports Core/Pentium/Celeron processors based on the 32 nm "Sandy Bridge" and 22 nm "Ivy Bridge" micro-architectures. It features two 240-pin DDR3 DIMM slots, supporting up to 8 GB of dual-channel DDR3-1333 MHz memory. Among the drive bays in the chassis are a 3.5-inch/2.5-inch SATA bay for hard drives, and a 5.25-inch bay for optical drives. The Hetris H61 Ultra packs an 80 Plus-compliant 270W power supply. It features a PCI-Express riser that allows you to install up to two PCIe expansion cards along the plane of the motherboard. Connectivity includes 6-channel HD audio, gigabit Ethernet, two USB 3.0 ports on the front, four USB 2.0/1.1 ports on the rear, a pair of serial COM ports, PS/2 keyboard/mouse, eSATA 3 Gb/s, and display connectivity that includes DVI, D-Sub, and HDMI. The Hetris H61 Ultra could also be sold with a number of entry-level CPU, memory, and HDD combinations.
