I had a great screwdriver for computer things but i cant find it, so im looking for a new one, anyone got any recommendation for a nice, good quality, preferably magnetic screw driver that should be good for dealing with various computer screws?
 
Phillips PH2 should do the smaller and larger screws no problem, according to Wiki.
#6-32 UNC screw

The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm). The optional UNC specification indicates the standard coarse thread is used which is defined for #6 screws as 32 tpi rendering 'UNC' redundant, however it may be seen when other specifications such as plating or other treatments are also specified. It is by far the most common screw found inside computer cases. It commonly appears in lengths of 3/16 in (0.1875 inches (4.76 mm)) and 1/4 in (0.25 inches (6.4 mm)) or less often 5/16 in (0.3125 inches (7.94 mm)). Non-standard metricized lengths such as 5 millimetres (0.20 in) are also sometimes encountered. Nearly every brand new computer case comes with a bag of these. They are commonly used for the following purposes, however there are many exceptions:
  • securing a power supply to the case
  • securing a 3.5-inch hard disk drive to the case
  • holding an expansion card in place by its metal slot cover
  • fastening case components to one another
  • usually, one or more #6-32 UNC screws hold the main cover on the case
They are almost always provided with a #2 Phillips drive. Sometimes a Torx drive is used instead. Both Phillips and Torx patterns may also be combined with a slot for a flat-blade screwdriver. Usually they are provided with a 1/4 in (0.25 inches (6.4 mm)) flanged hex head. Non-standard metricized 5.5 millimetres (0.22 in) flanged hex heads can also be encountered. Also common are pan head screws - a low disk with a chamfered outer edge. Because they are used in places where high torque is not required and easy removal and replacement may be desirable (such as on the side panels of the PC case), they are frequently available as thumbscrews with larger, knurled heads that can be removed with one's fingers or tools.


M3 screw

The M3 is a metric screw specifying a nominal diameter of 3 millimetres (0.12 in); and standard coarse thread pitch defined as 0.5 millimetres (0.020 in). The M3 is the second most common screw found in PCs. It commonly appears in many lengths from 1-20mm. Nearly every brand new computer case comes with a bag of these. They are commonly used for the following purposes, however there are many exceptions:
  • securing optical disc drives
  • 2.5-inch hard disk drives (HDDs)
  • solid-state drives (SSDs)
  • 3.5-inch floppy drives
M3 screws typically accept a #2 Phillips screwdriver tip.

Make sure it's one that turns both left and right. You don't want one you can only take screws out with!

And don't forget to make sure it's ambidextrous compatible, nothing worse than trying to undo a screw and there is not enough room for your left hand and the screwdriver doesn't work in the other hand
 
Agree with the comments about a PH2 - in general, it's best to use the largest drive you can fit in a screw. But make sure it's sharp, don't even keep worn screwdrivers around. You'd be amazed how much better things work if you follow this rule.

Which is fine if you have a sponsored YouTube channel and get stuff chucked at you.

For the rest of us, something good quality but not stupidly expensive, like a set of Wera drivers will be fine.

Edit:
