The Pi

If he ever gets one he'd probably mount it horizontally, just to troll.

The bootloader isn't affected by the architchure though, all you need is booting then the install can have drivers etc for the each system.

It exists just not quite in the way you want http://en.wikipedia.org/wiki/Vector_monitor

Wouldn't grub it's self be able to handle this? just have three installs on the single drive and away you go? It shouldn't be any different from triple boot on a single machine.

It's 75Hz not 144Hz

He means no current display has "everything" I think it's worth going with the Acer XB270HU, 4ms is worth the ips IMO

It doesn't take much energy to keep a disc spining (inertia of a disc and all that jazz) so when the disc isn't under any load the power consumption won't be too high. Your primary disc however while be under more load (cause of background stuff) even though it's an SSD it's perfectly resonable that the ssd can be consuming more power than the hdd and add in airflow differences and that temperature delta is perfectly reasonable.

So I can enable hair and run the game at 3.14159... fps

The temperature difference isn't huge so it can be summed up to placement compared to where the fan(s) are as well as load on the main drive In my system right now my main ssd is at 27C, my games ssd at 21C and my hdd at 22C, it happens. but it's all within spec so it doesn't matter.

He might be better off just dusting out air intakes/outtakes to see if the works first. It's not as simple as swapping HDDs, it does wipe the drive like the LoneRangerS said.

Cherry themselves sell keyboards for around the £60 mark, no leds or gamer crap but a full sized mechanical for fairly cheap. G80-3000 if you want blue or black switches, MX board 3.0 if you want red.

It works on AMD but not Nvidia: http://community.amd.com/community/amd-blogs/amd-gaming/blog/2014/05/30/mixed-resolution-eyefinity

You can just use adhesive tape to cover up the lanes as done here: http://www.techpowerup.com/reviews/NVIDIA/GTX_980_PCI-Express_Scaling/ "This review is made possible thanks to an awesome BIOS option given to us by the ASUS ROG Maximus VI Hero motherboard which allowed us to toggle the CPU's PCI-Express root complex between PCI-Express 1.0, 2.0, and 3.0. Using common plastic adhesive tape to cover up and disable lanes, we also successfully modified the number of lanes available to the GPU for these tests."

DNA testing it's self is actually really fast, in forensics though it takes ages to develop enough sample to analyse but the analysis it's self is still fast. Testing if two people are related is a fast process because you will always have enough sample but it's not usually urgent so you have to wait a while (I might be wrong but I think they do it in batches once they have enough samples) and it's far from cheap due to the needed people and lab supplies. (I'm a chemist, not entirely my area but the technique is based on chemistry)

Compare CPU to CPU not brand to brand at the same price point.
