PB Tech Penrose is a computer store at 4 Station Road in Penrose, Auckland, part of the nationwide PB Tech chain and holding a 4.0 rating on Google. A good computer store earns its keep on the details: which laptop actually suits your workload, and which small part fits the machine you already own. Regulars turn up knowing their model number, or with the failed drive or stick of RAM in hand, which turns a vague question into a quick answer. Larger outlets stock everything from complete systems down to individual components — drives, cables, power supplies — so they work for a full upgrade as well as a single fix. Component prices shift often, so it is worth comparing them online before you visit, and a weekday morning usually beats a Saturday queue. For the workshops, offices and households around Penrose, it puts a full-scale computer store within easy reach.
