    Why BuyRefurbished?

    • Lower capital costs.  Save money when you buy used Sun computers at highly discounted prices.   Whether you are buying wholesale or retail, used servers from Data Instruments can save you up to 80% off of list price. 
    • Increase current system longevity.  Consider refubished HP computers such as used Cisco switches, used routers, used Sun storage arrays and used Dell servers for back up, redundancy and to spread workload. 
    • New product performance doesn't justify purchasing new.  Price versus perfomance of used Dell computers and used HP network equipment is significantly lower than on new server and networking equipment.  We specialize in saving you money on Cisco switches, Dell servers, HP servers, Oracle servers and Sun servers.
    • Low cost hot spares for mission critical systems.  Buy used Sun computer and used network switches, motherboards, memory, disks drives and network routers which can be easily swapped out without waiting for your computer maintenance technician to show up. 
    • Compatibility with existing systems is a known entity.  Buy used HP servers that match your current HP servers and network equipment configurations.  Save yourself from new hardware glitches, software patches and network gremlins.
    • Familiarity with existing hardware means simplified deployment.  Buy used computers and forget about the installation manual.  No software and hardware compatibility issues either.
    • Reliability is a known factor.  You already know your systems like the back of your hand so buy a used Sun server or HP server from us.
    • Immediate availability, especially of spare parts.   Spare parts for used Sun RAID disk arrays, used Sun servers and used network equipment such as Cisco switches and Cisco routers is commonly available at lower costs than newer hardware that is harder to come by and possible on backorder.  Self-maintenance becomes practical and expedient with used computer parts.  Data Instruments can ship most items for next morning delivery around the country and can provide same day delivery in the Atlanta area.  
    • No training costs or learning curves.  Unlike new servers, refurbished servers and other computer hardware has already been in the market so there is much accessable information regarding fixes and patches.   
    • Higher ROI.  Data Instruments buys used Sun servers, used Dell servers, used HP servers wholesale and retail.  We refurbish servers, reformat disk drives, upgrade firmware in switches and routers and then resell these products to you at huge markdowns.  You get quality pre-owned computer hardware at new computer hardware prices.
