Sooner or later, a growing business will need a server of some sort to allow staff to share information and collaborate.
There may be fewer name brand manufacturers selling servers these days but the reality is that there's as much choice as ever, thanks to the ever widening range of server categories.
In this top ten, we've selected the crème de la crème of servers, ranging from servers aimed at small businesses to the sorts of bigger enterprises depend on.
Note that the cashback and trade-in offers mentioned in this list change every time so check with the retailers before committing to a purchase.
So here, in no particular order, are the top ten servers for small and medium businesses large and small you can build a growing business on for June 2016.
1. Dell PowerEdge T20 [barebone]
Servers do not have to be massive or expensive. Take the PowerEdge T20 for example; it has inherited a wealth of knowledge from the 20 years of experience Dell has building servers.
While it doesn't have any hard drive, it costs a mere £80 after a £70 cashback (although its price fell to as little as £69.98 in a recent past).
It has a Haswell-based Pentium processor that can clock up to 3GHz and supports up to 32GB DDR3 ECC RAM (this model comes with 4GB). Expansion capabilities include four SATA ports (32TB if you use 8TB hard drives), four I/O slots and 10 USB ports.
Astoundingly for a PC of this price, you also get two DisplayPort connectors, a VGA one, two PS2 and one serial port.
Other than a Gigabit Ethernet port, the other points of interest are a 290W PSU and an Intel-based RAID controller. Note that you won't find that very model on Dell's website and it doesn't come with an OS or an optical drive.
2. Dell PowerEdge T20 [Xeon]
A bewildering array of SKU (stock keeping units) means that you sometimes have to sift through entire price lists in order to get the needles in the proverbial haystack.
Take the T20 from Dell: You can buy it either as a barebone (listed above) or as a fully configured server. Opt for the latter and you can get an even bigger cashback (bringing down the price to around £340); even without it you're looking for a big discount compared to Dell's online suggested retail price.
Aimed at the entry level/SoHo market, the T20 manages to squeeze a lot of expansion potential into a compact, quiet mini-tower chassis plus it does come with a wealth of server features by default making it an ideal alternative to an office workstation.
Compared to the barebone version, that particular model features a more powerful Xeon processor (E3-1225 v3) with 32GB ECC RAM and a 1TB hard disk drive spinning at 7200RPM. It doesn't come with an OS but system administrators will appreciate the flexibility.
3. Lenovo ThinkServer TS140
Lenovo took over IBM's x86 server range back in 2014 and has built on the best of the ThinkServer tradition. The TS140 is the most affordable of the range and is a 4U enterprise-class server that competes with the Dell T20.
It comes with support for RAID 0,1,10 and 5 (via an onboard controller) with two 1TB 7200RPM hard disk drives in the boot. Like the competition, this one can accommodate up to four 3.5-inch HDDs, which means that it can go up to 32TB when loaded with 8TB models.
The Intel Xeon E3-1226 V3 processor should be powerful enough for small and medium enterprises. Lenovo also claims that the acoustics of the TS140 are even quieter than a typical library at 26 decibels.
As it is the case for the competition, you also get an impressive array of ports and connectors. Eight USB ports, four PCI/PCI-e slots, three video connectors (including a pair of DisplayPort), Serial, Gigabit Ethernet and three audio connectors.
4. Supermicro SuperWorkstation 5039A-IL
There is sometimes a very fine line between workstation and servers and there is probably no better example than the 5039A-IL from Supermicro. It is part of its SuperWorkstation range but works just as well as a server with acres of upgrade space.
Given that it is a barebone solution, the 5039A-ILis especially well fitted for small businesses with niche needs like creative houses that might want a server that's a bit more than just a print or file server.
This single socket, mid-tower behemoth (weighs in at 18.1Kg without any parts) offers the latest technology: Skylake processors (Xeon and Core i3/5/7), up to 64Gb of DDR4 ECC memory, USB 3.1, HDMI, twin Gigabit ports and 7.1 audio channel.
Its expansion capabilities are also breath-taking: DVI/DisplayPort/VGA, serial, eight SATA ports, six PCI/PCI-e slots and support for up to eight (yes, 8) hard disk drives, all powered by a 500W PSU.
Supermicro, while not a household name, is one of the biggest server and workstation manufacturers out there with decades of experience.
5. Fujitsu Primergy TX1310 M1
When you think about servers, Fujitsu is probably not one you'd think around. And yet, the Japanese manufacturer is one of the very few (if not the only one) that can claim to be involved in anything from SMB servers to, well, super computers.
The TX1310 is its entry level, SMB-focused server and comes with some pretty solid credentials plus an unmatched, industry-leading reliability guarantee.
If your server breaks down within the first year of purchase, not only will Fujitsu fix or place it, they will also refund you the amount you paid for the server.
Like pretty much everyone at this end of the market, it is designed to run silently 24/7 and offers RAID 0/1/10 but not 5. That model incudes an Intel Xeon E3-1226 v3, two 1TB hard drives and 16GB of RAM plus has a £150 cashback offer.
We liked the fact that it comes with an optical drive and has two Gigabit Ethernet ports for redundancy. With four DIMM slots and four storage bays, it supports up to 32TB of storage and 32GB of memory.
6. HP Proliant Microserver Gen8
One of the fastest growing segments of the server market is dominated by a single company. HP Enterprise's Proliant Gen8 Microserver has successfully managed to fend off competition – thanks to an attractive feature mix and plenty of discounts - and ultimately own that market.
These tiny servers have found a market well outside their niche with prosumers buying them en masse and touting their obvious advantages over NAS (network attached storage).
Despite being very small (less than 13l in volume) and light (less than 7Kg), it packs some impressive capabilities.
Support for Intel's Xeon E3 family, up to 16GB of RAM, on system management processor, two Gigabit Ethernet ports, one PCIe slot, support for RAID 0/1/10, a DVD writer, up to four hard disk drives, an internal microSD card slot, integrated Matrox G200 graphics chip and seven USB ports.
It only has a VGA port though and has only two memory modules. Note that this server currently comes with a £55 cashback offer that brings its cost to around £115.
7. Lenovo ThinkServer TS440
If you want something a bit beefier than the aforementioned servers, then consider the TS440. It is far more expensive but then again you get a server that's in another league.
For a start, it is far bigger than the previously mentioned servers with a 50L volume and a 25Kg weight. This 5U server runs on Intel's Xeon E3 models with Turbo Boost technology plus offers a three-year onsite warranty.
It supports up to 32GB of RAM and its integrated RAID controller offers the four main RAID types. There is a DVD writer, four fans, a 450W PSU and one Gigabit Ethernet port.
Up to eight hard disk drives can be installed and there are a whopping eight USB ports as well. There's a lockable door, support for ECC, a serial and a VGA connector. Sadly, no DisplayPort on this one despite what the Lenovo product page says.
8. HP Proliant ML350 Gen 9
Pitching in the same category as the TS440 is the ML350. This is an expensive piece of kit but looking at the feature list and it actually looks like a very decent deal.
Other than the fact that it has a dedicated, integrated graphics card (a Matrox G200 card), it offers a three-year onsite next business day warranty, a four-port Gigabit Ethernet port and support for 12Gbps SAS (note that it takes only 2.5-inch drives).
But there's more. This server runs an Intel Xeon E5-2603 v3 processor (not the usual E3 CPU) and supports two CPUs.
The E5 has six cores which makes it particularly well suited for more taxing tasks. We're also impressed by the amount of memory slots (24) that it has, allowing it to hit 3TB of memory, once 128GB LRDIMM roll out.
Oh and other than a lockable front door and a storage controller, this server earns cookie points for dual redundant, hot swappable 500W PSUs.
9. Scan 3XS SER-T20
A powerful server doesn't have to be expensive; that's essentially what Scan wants to convey to prospective customers. Specifically designed for the SMB market, it is engineered to be compact and as quiet as possible.
The UK-based vendor provides real time tracking at every stage of the server build process (the servers are built to order). Each come with three-year onsite warranty; what's more, you get a free recovery USB stick with diagnostic utilities.
If that wasn't enough, the components used in the system are amongst the best in our round up. Two Broadwell-based Intel Xeon E5-2603 processors providing a total of 12 cores and 30MB of cache.
Then there's 64GB of DDR4 ECC RAM from Samsung, a 1TB WD Enterprise-class hard disk drive, two Intel Gigabit Ethernet ports, a 850W PSU and support for eight hard disk drives.
Build by Corsair, the casing has a door and all the panels making it up are lined with noise damping material.
10. Asus TS500
Like Supermicro, Asus is not well known for its servers. Instead, the Taiwanese company, one of the biggest component vendors in the world, is popular for a wide range of consumer products including its motherboards.
Its TS500-E8-PS4 is a mainstream pedestal 5U tower server perfectly built for both workstation and server dual use. It features the latest Intel Xeon processor E5-2600 v3 product families, eight DDR4 DIMMs (supporting half a terabyte), six expansion slots, three 5.25 media bays and single 500W 80 PLUS Bronze power supply.
There are four 3.5" hot-swap SATA/SAS HDD bays which is also upgradable to eight HDD bays for flexible storage requirement. In addition, with Intel's Intelligent Platform Management Interface (IPMI) 2.0-compliant ASMB8-iKVM module in TS500-E8-PS4 you'll be able to monitor, control and manage the server remotely.
Other key specs include 10 SATA ports, a DVD writer, eight USB ports, a PS2 port, a VGA one and three Gigabit Ethernet ports. Note that this is a barebone server.
