Not bad at all, if you've got something to trade in you're getting a decent PC there. Newer generation than the i5 4460 in the Dell desktop deal I posted

That really does look like a Microtower!!!

Okay lets see if I can get this right now...

CPU £150, RAM £20, HDD £30, DVD writer £15, Windows 8.1 Pro (Upgrade to 10) £25, stock mboard £20, stock PSU £30, case £50 (thats generous) even if you charged £20 quid for stock keyboard and mouse would = around £350, that's 20 quid less than the deal.

For £377 you could build this, upgrade to 8GB RAM, pick up a cheap mboard for 30-40 and a slightly more powerful PSU (230V ain't much) and you've still broken even. If you can build a pc this isn't for you.

However if you can't or are looking for a cheap starter pc, this is a good deal, its a good cpu with enough storage and Windows, will do an office or basic email/work desktop fine.

If you have something worth 125 quid or more I suggest selling it and using the money for better compenents, thats just me tho

You'd hate America. They use 110 volts!

The point is you can get cashback when you send them an old PC back, which brings the price to significantly lower than any home build like-for-like project.

Also I'd love to know where you're sourcing full genuine Win8.1 for anywhere near £25 (from a reputable vendor)

Is it not £377 after the cash back? £427 before cashback

And cashback seems to be reduced to £50
