This thread is for people with the HP Proliant Microserver 4 BAY. This can be got for around £112 as HP are giving £100 cashback at the moment. Which is a really good price. The HP £100 Cashback ends December 31st so you have to order before then It has space for 4 Storage Drives and a Optical Drive. Also supports RAID 0 and RAID 1. Has 6 USB Ports and 1 Internal. Comes with 160GB HDD 7200rpm and 1GB RAM. This can all be easily upgraded though. Very Quiet too Considering a Netgear ReadyNAS is around the same price and only supports 2 storage drives and no optical drive, this is a great deal. Also you can install any OS you want on this. Like Windows Home Server etc. Would make a good Home NAS/Media Streamer or a server for a small business. Here is the Specifications. Dimension: 10.5 x 10.2 x 8.3 inch (26.7 x 26.0 x 21.0 cm) H x D x W Power supply:200 Watt Network Controller:Embedded NC107i PCI Express Gigabit Ethernet Server Adaptor Optical: None shipped standard, optional optical drive USB: 4 front, 2 rear, 1 internal + 1 eSATA rear Processorual Core 1.3 GHz AMD Athlon II Number of processor:1 Cache: 2 MB cache Memory type: PC3-10600E DDR3, operating at maximum of 800 MHz Memory slots: 2 DIMM slots Maximum memory: 8 GB (2 x 4 GB) Maximum internal drives: 4 pluggable drives Maximum internal storage: TB (4 x 2 TB 3.5” SATA drives) Storage controller: Embedded SATA controller RAID 0/1 Expansion slots: 2 PCI Express (x16 and x1) So what does everything think of it who has it? And what OS you going to install? Anyone sent away for there cashback yet and got it?
