At ~£3.6k ex-VAT for an Asus 2U SP5 rack box, the RS720A-E12-RS12 looks like a “pay for reliability, not for flash” kind of purchase. Asus is usually strongest here when you want solid server basics in a predictable 19" footprint—good for SMEs and IT teams that don’t want to spend their evenings fighting hardware quirks. If you’re building a small virtualization cluster, running business apps that need stability, or consolidating services where downtime really hurts, this class of chassis is the right direction: it’s designed to live in a rack and be managed.
That said, I’d only buy it if the rest of the bill of materials makes sense for your workload. The biggest risk with these mid-priced 2U platforms is ending up paying for “rack form factor” while under-spec’ing the parts that actually drive performance (and then you’ll feel it later in day-to-day throughput). Before you commit, sanity-check that the configured CPU/RAM/storage balance matches what you’re running and that you’re comfortable with the management and support path in your environment. If you’re mainly doing low-intensity workloads or you don’t need 2U density, there are often better value options—either cheaper towers/1U setups or refurbished builds that deliver more compute per pound.
If you tell me what you plan to run on it (virtual hosts, database, file/app workloads, expected user count), I can give you a clearer “yes, this is good value” or “no, you’ll regret the trade-offs” verdict.
