Upgrading your memory?  Use this website to SCAN for the type of memory your system needs, as well as to determine how many open slots you have available in your system to upgrade.  This is the ONLY location we purchase memory from for all our clients: www.crucial.com

Purchasing a new system?  The only desktop and laptop we currently recommend is from Dell.com.  We HIGHLY advise you to purchase the three year on-site warranty with your systems - it will pay for itself over time - usually substantially: www.dell.com  OCS will be building and selling our OWN server/desktop systems in 2009 - pelase give us a try....you will be pleased

Virus solutions on the table? We only recommend Trendmicro.  We have found it to be especially functional and proficient in trapping viruses and trojans in the field.  This is particularly true for clients running Exchange Email servers at their locations.  This site will show you all the features they offer, as well as having a link to the latest viri in the 'wild': www.trendmicro.com
