well, depending on your budget..if your budget for gaming means they can suggest higher spec. if you wish for normal daily use like internet surfing, watching movie or light fb games then they will suggest lower spec rig which is cheaper too.

if you got 2.5k, just built a rig that will last you for few years.

i got this from Idealtech, Aerocool StrikeX Advance white RM225.... There's 4 fans built in, 2 front, 1 top, and 1 rear. One disadvantages of this casing is its bracket to hold HDD and SSD a bit weak.

When my rig arrive, the hdd and ssd came loose from the casing which maybe due to transportation. When i tried to put back, its still a bit loose but its good enough i guess, since the cpu will be stationary anyway.

they came out with this model when i got my rig

for me it would depends on existing software, as i used to autocad c3d 2010 so cant run it on win 8. heard win 8 interface not bad... still prefer win7 as its more mature than win8
