Industrial strength versatile hosting from £10 + VAT pcm.
Our server is a dual Xeon 3.6 ghz with 16 gb RAM. It uses 10,000 rpm SCSI hard drives in a RAID5 array. All data and settings are backed up daily onto separate drives - it is a very fast and secure system.
There may be cheaper options available but we have used this system for over two years and it has never let us down. It is also very easy to administer should you wish to add domains and extra mail facilities.
