Rethinking desktop real estate in the call center era

Say hello to the little machine with big savings

Sponsored Feature The tower PC under every call centre desk carries a hidden cost, and it's bigger than you think. Many call centers are burning through £54,000 to £135,000 a year on electricity alone, according to Alan Spohr, marketing director for ASUS UK. Lights left on, outdated desktops humming overnight, and cooling systems battling aging server rooms all add up. Before long, you're paying commercial rent for space occupied by beige boxes that are draining your bottom line. But there's a solution. The ASUS Next Unit of Computing (NUC) offers a way to rethink desktop real estate and reclaim those wasted resources..

"From what we're hearing directly from call center operators, the biggest challenge isn't just about squeezing more desks into a limited space, although that's certainly a factor," says Alan Spohr, marketing director for ASUS UK. "It's about the squeeze they feel from all sides: complexity, maintenance, and a lack of agility."

ASUS has an answer to this problem, in the form of the Next Unit of Computing (NUC). Intel first showed off this concept at the 2012 Intel Developer Forum, pitching a four-inch square motherboard crammed into a case small enough to hold in one hand.

NUCs evolved through thirteen generations before the chipmaker handed the reins to ASUS in September 2023. The handover included both hardware designs and software, along with staff from Intel's NUC division. Today's NUC 15 Pro, measuring 112 x 144 x 42mm and powered by Intel Core Ultra Series 2 processors, represents ASUS's own development of the platform. It's built for commercial and edge computing rather than the hobbyist tinkerers who adopted earlier generations.

Spatial economics

Shrinking the hardware footprint has knock-on effects that ripple through operational budgets. Swapping towers for mini-PCs uses 15-20% less space per workstation, says Chris Davies, Country Product Manager for ASUS UK.

In a 500-seat deployment, Davies puts the floor space reduction at 2,500 to 4,000 square feet. At prevailing UK commercial rates, that shaves between £75,000 and £120,000 annually from the operating budget.

VESA mounting also makes it possible to shift the PC from floor level to the back of the monitor. With toolless clips, a technician can replace a dead unit in under 60 seconds. Conversely, tower retrieval runs three to five minutes per unit.

The shift toward hybrid work amplifies these advantages. "Hotdesking has become a major component of this new model," Spohr explains. "Instead of issuing a single device that agents carry back and forth, operators are increasingly adopting a dual-setup approach: a managed device at home and a shared, secure workstation in the office." A compact system serving multiple shifts makes more sense than dedicating a full tower to each name on the roster.

How hybrid processor architecture helps call center operations

Beyond its physical footprint, what's inside the NUC 15 Pro is important to cell centers. But before we dive into the specifics, let's talk about "hybrid" processor architecture. Think of it like a team of workers: some are specialized for heavy lifting (performance), while others are better at handling routine tasks efficiently. A hybrid processor combines both types, allowing it to intelligently allocate resources based on the workload.

How does this help call centers? Computing bottlenecks can appear based on what call center agents are doing. Voice and AI workloads push the CPU hardest. Heavy CRM users with fifteen browser tabs open tend to hit memory limits first. Operations doing extensive call recording or screen capture may find I/O or network bandwidth constraining throughput before processing power becomes an issue.

Intel's Core Ultra Series 2 chips split their workload across two distinct core types. The P-cores focus on performance, tackling latency-sensitive work. In a call center setting, that includes softphone audio processing, CRM queries, and the AI copilot suggesting responses while an agent types.

E-cores are designed for efficiency, absorb everything else. These will handle system maintenance, background syncing, and event recording that runs constantly but invisibly for compliance.

The hybrid architecture keeps background housekeeping off the critical path, while P-cores stay available for whatever needs immediate attention.

"This intelligent separation of tasks ensures smooth multitasking, reduces power consumption and heat generation, and maintains consistent responsiveness, even in a 24/7 operation," says Davies.

The efficiency gains are substantial. ASUS claims a 40-50% improvement in performance-per-watt compared to previous generation desktop processors. That means a Core Ultra chip running at 45W TDP can match or exceed what a 65W 11th Gen part delivered.

For thermal planning, Davies recommends targeting the 20W to 35W range as the sweet spot where performance stays solid without overwhelming compact chassis cooling.

Energy savings mount up

Energy was once a budgetary line item that nobody scrutinized too carefully. That's changed now. "Energy has definitely moved from being a background concern to a real priority for call center operators, especially here in the UK and across Europe, where energy costs have been particularly volatile," says Spohr.

The calculations favor compact, efficient hardware. Davies estimates a 500-seat operation could bank £40,000 to £70,000 in combined energy and cooling savings over three to five years by moving away from traditional towers.

While most operators won't ripp out their HVAC systems to capture these gains, new builds can design around lower thermal loads from the start.

ASUS Power Sync adds another layer by monitoring workstation occupancy and throttling idle machines automatically. In hot-desking environments where seats sit empty between shifts, Davies puts the additional saving at roughly £1,500 annually across 500 workstations. That's a 12% reduction in energy consumption that requires no behavioral change from staff.

The little machine that keeps going and going

When agents do get back to their desks, those machines had better be working. Call centers surface failure modes that never appear in typical use. They have to manage thermal cycling as shifts change and HVAC adjusts. Dust still accumulates in fans just as it does in towers, and there's a risk of component fatigue from machines that never switch off.

"Downtime equals increased customer waiting times, or even lost calls," notes Davies.

There are certifications that prove computers are up to demanding environments like call centers, and ASUS supports them. MIL-STD 810H certification provides one layer of assurance. It covers temperature extremes, humidity, shock, and vibration testing that goes well beyond what office equipment typically endures. ASUS supplements this with internal protocols designed for the sustained stress of commercial deployments.

When failures do occur, recovery speed is a major factor. The NUC Pro Software Suite includes a Player Failover function that can activate a backup unit automatically, minimizing the gap between failure and restoration.

For fleet management, ASUS Control Center handles device monitoring, firmware updates, and predictive maintenance alerts. It sits alongside existing enterprise tools rather than replace them. "Enterprises typically run ASUS Control Center alongside tools like Microsoft Endpoint Manager, Intune, or SCCM," says Davies. "The key is integration."

Connectivity and display architecture for modern workloads

Fast connectivity is important for machines that are dealing with customer sessions in real time. While Wi-Fi 7 specifications promise throughput up to 46Gbps, real-world performance in dense environments will be lower.

"We strongly recommend using wired Ethernet connections for call center deployments," says Davies. Wireless has its place for guest access and mobile devices, but mission-critical voice traffic needs the consistency that only copper provides.

The NUC 15 Pro handles that with Intel 2.5Gb Ethernet alongside dual Thunderbolt 4 ports and twin HDMI 2.1 outputs. That's enough to drive four 4K displays from a single unit. While few call center agents need that many pixels, this opens doors elsewhere. "They can be deployed in other environments, such as control rooms, digital signage applications, or even creative workstations," Davies explains.

A focus on employee ergonomics

No matter how many pixels they're looking at, it's critical to take care of an agent's peepers. Aside from being unhealthy, eye strain is a productivity drain. ASUS builds TÜV Rheinland-certified flicker-free and low blue light technology into all its business displays as standard.

The ASUS VA24DQFS monitor pairs a 23.8-inch Full HD IPS panel with full ergonomic adjustability. It tilts, swivels, pivots, and is height-adjustable, so agents can position screens properly rather than hunching to accommodate fixed hardware.

For workflows demanding color accuracy, such as quality assurance, design review, or video verification, the ProArt PA279CV offers 27 inches of 4K resolution with factory-calibrated Delta E below 2. USB-C with 65W power delivery keeps cable management simple. Both monitor lines use 85% post-consumer recycled plastics, which helps tick the sustainability boxes without compromising build quality.

For true ROI, go beyond capital cost

IT teams interested in this investment should look beyond capital cost when projecting ROI, Spohr says. "While upfront cost still matters, it's no longer the sole deciding factor," he says. "Teams are now weighing energy consumption, cooling requirements, and overall environmental impact together."

The sustainability arithmetic favors compact systems. Lower energy consumption across the device lifespan, smaller material footprint during manufacture, and reduced e-waste volume per replacement all contribute.

"When you factor in these advantages, the environmental math generally lands in favor of Mini-PCs/NUCs," says Davies.

Human effort is another factor. Rolling out 500 mini-PCs takes roughly 83 hours of IT hands-on time spent mounting, cabling, imaging, and testing. The equivalent tower deployment runs closer to 100 hours. That 17-hour difference represents half a day's work for a five-person team, freed up for something more useful than crawling under desks.

ASUS backs the hardware with 24/7 support access and a three-year warranty covering more than 50 countries. Optional extras include warranty extensions, accidental damage protection, and defective drive retention for organizations with strict data handling requirements.

For organizations juggling hybrid workforces across multiple sites, Intel vPro support on selected models also enables remote management and hardware-level security features without requiring physical access to each machine. That matters when your endpoints are scattered between head office, regional hubs, and agents' spare bedrooms. Cost savings on maintenance truck rolls can add up quickly.

NUCs don't require a leap of faith. ASUS inherited a platform with over a decade of commercial deployment behind it. The NUC 15 Pro represents evolution rather than experiment. And call centers make a useful reference case precisely because they push every variable to extremes. They require maximum seats per square foot, and have zero tolerance for downtime.

So if NUC economics work in a call center, they work in less demanding environments too. The tower under the desk isn't just taking up space anymore. It's leaving money on the table.
