Linking into the "HotUKDeals - Wow - MSI AE1900 WHITE 18.5 INCH AI1 TOUCHSCREEN NET-TOP PC REFURB - Only £289.98 delivered @ Argos Outlet" deal, I was asked to find a cheaper alternative by a mate (he's on a pretty tight budget) and I found this one over at Amazon UK (direct from them).
It doesn't have the integrated touchscreen as the MSI AE1900 deal but it's pretty much the same basic technical specifications (I have submitted a message to Amazon UK support to get further information on them) - the details are listed below.
Technical Specs (from Amazon UK)
* Acer eMachines EZ1600 All-in-One PC
* Intel Atom (N270) 1.6GHz Processor with 512KB L2
* 1024MB 533MHz DDR2 RAM
* 160GB Serial ATA Hard Drive
* 18.5 inch LCD TFT Display
From searching online the expanded technical specs are listed below - note that the model number is different BUT they are meant to be one in the same (the difference appears to be regional zones from where it's sold in).
