Dublin's IT partner
for over 25 years.
Eclipse Technology Limited — trading as Castle Computers — has been designing, managing, and securing IT environments for Irish businesses since 2000. We're not a faceless helpdesk. We're the team your people actually know by name.
Built on trust.
Grown on results.
We started Castle Computers with a simple belief: that every business, regardless of size, deserves enterprise-quality IT without enterprise-level complexity or cost.
Over the years, we've built long-term relationships with clients across Dublin — from single-person operations to 300-user businesses. Our client retention rate tells that story better than any marketing copy could.
We don't just fix problems — we prevent them, through proactive management, smart infrastructure decisions, and a genuine commitment to your business running smoothly.
Our values in practice.
When something breaks, you need it fixed — not tomorrow, not in a ticket queue. We pick up the phone and we get there.
We monitor your environment constantly and address issues before they affect your team. You shouldn't have to tell us something's wrong.
We treat every client as a long-term relationship. We know your systems, your staff, and your goals — not just your ticket history.
We recommend what's right for your business — not what's most expensive or most fashionable. Sensible IT that works is always the goal.

We'd love to learn about your business and show you how we can make IT the last thing you need to worry about.
