Gary Fowle, C2000's general manager for PC systems, confirmed it was time the company distributed a Sun product.
The forerunner of Computer 2000 UK, Frontline Distribution, had a contract with the vendor but it ended ten years ago.
"There are not many SME dealers selling Sun's own platform because its mid-range products were aimed at [corporates]," said Fowle.
"This is Sun's first attempt at this market. Sun was looking for a distributor that could give a real breadth of customers and there is huge potential in the SME and education sectors - we can take it into that space," he added.
C2000 has undertaken a reseller education campaign and recruited around 100 dealers to partake in Sun Microsystems' volume products reseller (VPR) programme which accredits them to become Sun iForce VPRs.
Mark Littlewood, Sun product sales executive, said: "Dealers do not have to have OS skills, which removes the need for engineers, and it can be set up in 15 minutes."
He added the market potential was huge, with "around 35,000 schools and 643,000 SMEs that have Internet connections".
Sun has 150 dealers on board but is looking for up to 250 by the end of the year.
Gartner Dataquest claims there will be 1.3m server appliances installed on a worldwide basis by 2004.
The Cobalt range is also distributed by Spot Distribution in the UK.
