Question 1

What's the difference between a Mini PC and a Small Form Factor (SFF) PC?

Accepted Answer

A Mini PC (or MFF — Micro Form Factor) is significantly smaller than an SFF machine and typically offers no PCIe expansion slots, making it ideal for space-constrained desks but difficult to upgrade. An SFF PC, like the Dell OptiPlex 7020 SFF or HP Pro 400 G9 SFF, is still compact but retains at least one PCIe slot for adding a graphics card or other expansion card. If you ever anticipate adding hardware, go SFF over Mini PC — the size difference is modest, but the flexibility gap is substantial.

Question 2

Is 8 GB RAM enough for a business desktop PC in 2026?

Accepted Answer

Technically yes, practically no — 8 GB will struggle with modern Windows 11 Pro alongside a browser, Teams, and Office running simultaneously. For any machine that will be used as a primary work computer, 16 GB DDR5 is the minimum we'd recommend. The cost difference between an 8 GB and 16 GB configuration is usually modest relative to the total machine price, and the day-to-day performance difference is significant.

Question 3

Should I choose a processor with a 'T' suffix (e.g. i5-14500T) or the standard version?

Accepted Answer

The 'T' suffix means a lower TDP (35W vs 65W), which translates to less heat, quieter fans, and lower electricity consumption — but also reduced performance under sustained load. For light office work, the T-variant is a sensible choice, especially in open-plan or quiet environments. If you're running anything computationally intensive for extended periods — compiling, rendering, large spreadsheet calculations — the standard processor will maintain higher clock speeds without throttling. Don't pay the same price for a T-variant as a standard chip; the T should be cheaper or come in a more compact form factor.

Question 4

Do I really need Windows 11 Pro, or is Home sufficient?

Accepted Answer

For business use, Windows 11 Pro is worth it. The key features missing from Home are BitLocker drive encryption, Remote Desktop (both hosting and connecting), Hyper-V for running virtual machines, and the ability to join a corporate Active Directory domain. If you're deploying machines in a managed IT environment or need to access them remotely, Pro is non-negotiable. For a home machine used for browsing, media, and light productivity, Home is perfectly adequate — and some Acer Aspire models offer a lower entry price as a result.

Question 5

Which brand offers the best after-sales support for desktop PCs in the UK?

Accepted Answer

Dell and Lenovo lead on business support, with next-business-day on-site warranty available on their commercial lines (OptiPlex and ThinkCentre respectively) — a genuine advantage if machine downtime costs you money. HP's ProDesk and Pro Tower lines offer similar coverage. Acer's consumer Aspire range defaults to a standard 1-year return-to-base warranty, which is slower and less convenient. For custom builds, PC Specialist provides solid UK-based support. Whichever brand you choose, always check what warranty tier is included before comparing prices — a cheaper machine with a weaker warranty can cost more in the long run.

Question 6

Are there any pitfalls to watch out for when buying a cheap desktop PC?

Accepted Answer

Yes — the most common trap is buying a machine with 256 GB storage and 8 GB RAM at a low headline price, then discovering it needs immediate upgrades to be usable. Also watch for machines sold with Windows 11 Home when your environment requires Pro (the upgrade licence adds cost). On the form factor side, some ultra-compact Mini PCs have soldered RAM that cannot be upgraded at all — check the spec sheet carefully. Finally, be wary of configurations using older-generation processors dressed up with modern branding; always verify the CPU generation (13th vs 14th gen Intel) rather than just the tier (i5, i7).

Question 7

What's the advantage of DDR5 over DDR4 in a desktop PC?

Accepted Answer

DDR5 offers roughly double the memory bandwidth of DDR4 and runs more efficiently at lower voltages, which benefits both performance and thermals. In practice, for everyday office tasks the difference is marginal — but for workloads that are memory-bandwidth-intensive (video editing, large database queries, virtualisation), DDR5 provides a measurable advantage. More importantly, DDR5 is the standard on 13th and 14th-gen Intel platforms, so a machine shipping with DDR4 on a modern chipset is likely using an older or cost-cut memory subsystem. It's not a dealbreaker, but it's worth noting when comparing similarly priced machines.
