I've bought loads of computers, both for myself and on behalf of others, from A C Computer Warehouse. They're just the same as brand new computers with the same specifications. (The drives have been wiped and a completely fresh installation of Windows loaded onto them, so they're not 'weighed down' by anything that a previous user might have loaded onto them).
A quick look at the PC World website shows that the majority of desktop computers they sell still use conventional hard drives. Indeed, when their tower computers are listed in order of ascending price, the first 11 models in their range all use HDDs, with only the 12th (at £529) having an SSD:

So SSDs are still 'a bit of a luxury' when purchasing a new computer.
The sizes of some of the HDDs available now are totally pointless for people who don't, for example, store masses of video files on their computers. (1 TB might be necessary if you're heavily into video editing but many home users don't require anything like that amount of storage. The old Windows 7 machine I'm using to type this has only got a 64 GB HDD but that's enough for what I use my computer for).
SSDs are definitely the way ahead though. That's why, out of all the refurbished desktops listed here

I'm particularly considering buying a model with an SSD. The cheapest on offer is priced at £159 but an extra tenner gets you double the storage capacity and double the RAM too. So that's why I find this model, at £169, so attractive for my needs:

(Someone who's heavily into video-editing might laugh at a drive capacity of 'only' 240 GB but that's nearly 4 times the size of my current HDD and clearly more than adequate for my fairly basic needs).
