Perhaps, it'll be waiting at least till the second half of the year though.

Since his pc is infected and corrupted already, might as well turn it off and unplug it from the network. Try your best to backup what you can on your PC to an external hard drive or something, and make sure that hard drive doesn't connect to the network afterward. An antivirus doesn't hurt but tbh they don't work too well most of the time.
 
Aside from that there's not much I can think of off the top of my head, good luck

Basically you're looking at an i3 and not much else. http://uk.pcpartpicker.com/part/intel-cpu-bx80646i34170
If you can find a cheap i5 on a deal or something that would be great, but for 100 GBP that would be pushing it a bit. Cheapest one on PCPartPicker is 144 GBP http://uk.pcpartpicker.com/part/intel-cpu-bx80646i54460

Any case with ATX case with dual 140mm + 120mm rad support will work. PCPartPicker has a pretty accurate compatibility checker, if you add the H110i GTX and MSI card to your part list and then try to add cases it'll only show those (it thinks) are compatible with the cooler.
 
Some options:
Fractal Design Define S, ~$80
Phanteks Enthoo Pro $90-100
NZXT H440 ~$100
 
Any good brand 550 W or more power supply is fine.
 
Seasonic G 550 W (~$80) 80+ Gold
XFX XTR 550 W (~$80) 80+ Gold
Corsair CS550M (~$80) 80+ Gold
EVGA SuperNova 650 W (~$70) 80+ Bronze

Case: What @ExcaliburVII said
PSU: Tiers 1 to 3 on this list please:
 

 

Looks good, the Nano S isn't a particularly small ITX case though so if you want to go smaller then something like a Node 304 would be good. If you don't mind the size though then the Nano S is fine.
 
Nano S supports bigger CPU coolers (up to 160mm) so you don't have to go with the smaller NH-C12P, but 160mm is still very very tight for most tower coolers. NH-C12P performs well anyway so eh.
 
Also Nano S only supports up to 160 mm PSUs and the GQ650 is 165mm. Whether or not that'll really make a diference I don't know, but they also recommend even shorter than 160mm for cable management. Perhaps something like this might suit you better (140mm, 650w, 80+ gold).

Good list of short PSUs

For 80 bucks you get an excellent 80 plus gold fully modular EVGA 550W PSU

For 60 bucks a non modular bronze certified EVGA 600B, still a totally solid PSU

I was gonna add more options, but honestly for the prices those PSUs are as good as it gets.

WALL OF TEXT WARNING!

Ok here's an in depth reply.
 
1) Remember that this guy was a VP for AOL so assume he already knows about every single point on this list. He knows the worst case scenario and knows how to push for it. His example it's still valid because Customer Service should be measured by the worst case scenarios though.
 
2) I am 90% sure this call was taken outside of the United States. I know this because I know there's Comcast call centers outsourced to my very city of Monterrey, Mexico. In fact I have personal friends who worked on this specific retention campaign from Comcast as well as other areas related to Comcast as well like sales.
 
3) If you think Comcast does all this to save money, you'd be right: they offer something like USD $4 per hour to call center employers here and for middle class young people that's actually a competitive salary.
 
4) Comcast doesn't directly hires any of them. They hire third party outsource telemarketing and outsourcing specialty companies to do so. That's not all, this 3rd party companies hire a 4th party company to do the actual recruiting and hiring as well as handling all workforce contracts, payroll and legal labour disputes.
 
This means that this 4th parties companies are not even known to Comcast at all. And even locally they are as shady as they come: they often target young and inexperienced people (Seriously as long as you speak English fluently you don't even need a GED to get in, some places don't even ask for any sort of references or drug screening at all, just 2 forms of ID, an address and you're in) and offer only perpetual temp contracts to avoid any seniority. Mass firing as well as forced resignations to avoid paying legal terminations are often standard practice. This companies actually go as far as to keep databases of every single employee that starts any sort of legal remedy against any company even if the employee was in the right.

5) Now onto the job: Since they literally hire barely competent people (I've trained guys who barely knew how to use a computer and didn't have a basic understanding of relatively common things asking me advice on how to cash their first checks and such, a lot of very humble people who happen to know english due to dual citizenship and such come to this places)  they don't expect much from them. In fact they have a script an decision script that they require everyone to follow. This is not optional, this is not just a tool, this is a requirement. I think it should start to make sense for you guys now.

Now how do we know that they follow this? First of all we have several tiers of people who's entire job it's to monitor calls and make sure employees follow this scripts and guidelines diligently. This means we can dock their paychecks, reprimand them and eventually terminate them if they do not follow this rules.

6) So now the guy has to follow the script. That's not the end of the story though, he has several other things to make sure he complies to this. First by following the script which includes every possible thing a customer can say as a reason to want to terminate the contract, he is guided through a series of rebuttals. Not only that but as soon as he gets the call he has all the customer information screen, included a value rating system. Comcast keeps track of how long a customer has been with them and what is his credit rating with the company (how many times he's been delinquent in his payments, etc) According to this value ratings they are entitled to offer several perks including free added services, discounts, etc. the highest value clients the better. Not only that but they keep a special rating for VIP customers that include not only celebrities and such but people Comcast knows to be influential and such and those are automatically routed to a special team that gets the AAA treatment and such.

7) If all that fails, the call gets escalated to a more senior representative, often onsite but there are off site teams working for American call centers as well (since having a non-native accent is a common complain) as well as the Agent's supervisor locally. Only they are again, required to have gone through their scripts or other special circumstances (like a particularly irate customer) but this escalations are often discouraged and only accepted as a last resort. The second tier reps have even more benefits to offer up to an including heavy price reduction and payment rates not available at all for new customers and several months of flatout free service hoping you'd reconsider.

8) That's not all the guy doing the "save" call has to worry about. Even though he's not even allowed to deviate from scripted responses and very specific tiers of benefits offered as compensation depending on the customer value rating, their paychecks, bonuses and performance ratings depend on save quotas, meaning that they have to save at least an X % of cancellation attempts in order to be in goals. Failing to achieve this numbers also results in reprimands and eventual termination of the employee.

The term "boiler room" and "sweat shop" easily applies to this places. And again I am not justifying any of this, I am just saying that Comcast damn well knows all of it, encourages, specifically ask for call center partners to measure this and holds the entire operation on short term contracts with aggressive goals otherwise the entire operation gets canned (as it often happens, it's not unusual for a 200-400 employee operation to go down inflames immediately) So this is beyond just a crappy call or an exception, the only difference is that an experienced person like him knows how to completely break through the scripts and canned answers and force the unreasonable situations Comcast and virtually all other telecom companies like them encourage.
