UPDATE 04/06/2015 10.22pm: PC developer Syber has joined Alienware in revealing its line-up of Steam Machines.
Available in three models priced at $499, $729 and $1419 (roughly £325, £475 and £924), there's quite a lot of flexibility in these SKUs.
Unlike Alienware's Steam Machine's, Syber's catalogue is fully upgradeable.
For the full rundown, head over to Syber's official site.
ORIGINAL STORY 04/06/2015 4.53pm: Valve has finally announced a release date for the first wave of its Steam Machines, which will launch at retail on 10th November.
But you can also pre-order one of the Linux-based gaming PCs and get it almost a month earlier, on 16th October.
Alienware's Steam Machine is first up with four flavours that range in price from $449 up to $749 (around £295 up to £490).
Valve's £39.99 / €54 Steam Controller (the one that looks like a robotic owl) is available for pre-order as well.
So too is the Steam Link box (a tiny gizmo that streams games from your regular gaming rig to your telly screen), which will also cost £39.99 / €54. The two can be purchased together in a bundle if you so desire.
Steam will open UK pre-orders shortly here, via Valve's website. You will also be able to buy the Steam Link and controller at GAME from 16th October when pre-order customers begin receiving their PCs.
